General Mark Twain Discussion / farewell 1964Mark Twain
« on: December 01, 2012, 09:23:59 PM »
I let my friend, Steve, keep the boat on my lift for the rest of the summer and use it when he visited. Steve knew nothing about boats and I showed him how to operate it and promised to winterize it in the fall.
I got a call from Steve early last week and we agreed to meet over coffee last Thursday to winterize the boat. I was a little apprehensive about seeing the boat since Steve had never owned one before.
When Steve opened the door I was very surprised. Steve had detailed the boat and waxed it with several grades of polishing compound and his Porter Cable buffer. The boat looked better than when I owned it. An amuzing story is that Steve has been letting his new Infinity G37X sit outside so as not to crowd the Mark Twain. I am convinced it is in good hands.

Many of you here have seen my 72 MT 15\' VSonic I/O on the site. The hull is in nearly new condition and has been stored inside since new. I was in the process of re-powering it and I have abandoned the project and sold the engine.
If you or anyone you know is considering a restoration, refurbishment, or a floor and stringer job on an I/O MT, or any other make that used a Mercruiser Alpha 1 this would be the perfect hull. There is no stern drive unit or interior, but it would be much less work to swap the parts to this hull from a old junker with rotten stringers/floor/interior than try to restore it.
I hope someone here is interested. Hulls like this don\'t come along often.
It comes on an old ragged trailer that is road worthy, but would win the ugly trailer crown hands down.
Please, someone save this MT hull.
The boat is located in northern Wisconsin. If I have no takers its off to the landfill in May.

General Mark Twain Discussion / Can someone help me find a boat?

I have  been trying to find a photo of a late 60s to mid 70s Mark Twain that was posted on this site. I think is one of the prettiest boats I have seen. The photo was posted about 2 years ago of it beached on a river with the MT pennant on the front. I believe there were some photos of it at a dock also. If I remember the owner was from the St. Louis area but I may be wrong. I have gone through a lot of old posts but can not find it. I cut the photos of it and have misplaced them. I would like to find out who owns it. I believe it is a formerly active member of the site. I may be interested in finding one like that for my own, but until I find one I want to drool on the photos. I am not sure what I am doing with my 72 project and my wife thinks I should abandon it and buy a new (used) boat. I want to show her a photo of this boat.

General Mark Twain Discussion / Paging Haulnazz for some information

Would you mind sharing some information about your engine? I have not heard back from the rotary shop yet, but I have been adding up the things I need and I don\'t see how I can complete the engine for less than $5,000.00.  If I need a new engine management system, which is likely, that will add additional cost. The Alpha EMS I have is an older unit no longer supported and runs in open loop. I would need to install an O2 sensor in the exhaust connected to an A/F ratio meter just to verify that it is set up right. If I install a new EMS I need an O2 sensor to run in closed loop and I need to have a tuner ride along with me to set it up. I  have no way of making a tuning pull with the engine  with the boat out of the water. Tuning a new EMS starts at about $500 when done in the shop on a chassis dyno. At the lake it is another story, unless the tuner will do it for standard fee, a day of boating, and lunch.
I am wondering how much weight I could shave off of a 351 (one of my favorite engines by the way) by installing aluminum heads, intake, possibly a lightweight starter (has to be sealed for marine use), and anything else I can do to save weight. I have seen a few complete 351 Mercruisers on ebay including all parts, and I believe it would bolt right up to the Alpha I have since it is rated for 300HP.

I really want the rotary, but my family is getting worried about the complexity of operating and maintaining the boat with that set up. With luck the boat will be my daughters someday and she asked where she would go to have it serviced and maintained. I did not have a good answer.

Anything suggestions are appreciated.

General Mark Twain Discussion / I may be Twainless for a summer.
« on: April 14, 2011, 09:10:50 PM »
I posted my 64 MT on ebay for sale, and I have no information yet about the engine for the 72.  When I get the engine back I still have a lot of work to do to the 72 boat. I will post some photos of the progress as it comes along. If my 64 sells I will have to endure a summer without a Mark Twain for the first time in many years. I guess this year I will be fenced in on a floating patio. I feel really old now.

On the positive side it may be the inspiration I need to get the 72 done.

General Mark Twain Discussion / 1972 Mark Twain 13B rotary engine swap
« on: March 23, 2011, 08:31:12 PM »
I have decided that this is the year that I will get my 1972 Mark Twain 15’ engine swap project completed. I have tried to do this before, but never completed it. This boat will replace my 1964 Mark Twain that I will be selling this summer.

I bought this 72 MT back in 77. It didn’t run because it had a Mercruiser 90 stern drive, which used a Renault Gordini engine. The engine was light, but not well suited for a boat. It was known to break about 1.5 times on each outing. It was a typical sports car engine, good power at 6000 RPM, but not much torque at the low end. This engine was not happy running 4 to 5 hours at 6000 RPM on my trips from Chicago to Waukegan and Kenosha in Lake Michigan. After one year of constant repair I put it in the garage not to emerge until 1999.

My friend, Mark, bought a new Imperial runabout with a Mercruiser 120. On one of it’s first outings we cracked the hull out on Lake Michigan. The Imperial went back for factory warranty, but cracked again after only a couple outings. By this time Imperial had gone out of business. I bought the boat and installed the 120 in my 72MT in 1999.

The 72 was nice with the 120, but it was heavier than the 90 it replaced, as were my friends and I. It struggled pulling up a skier with 4 passengers and a cooler full of refreshing beverages in it. In 2005 I removed the 120 and began the process of replacing it. I bought a boat engine from a company that is now defunct, Rotary Power marine. It is a Mazda 13B rotary engine that has been marinized and supercharged. It produces about 270HP and weighs 335 pounds, a great power to weight ratio.

Several years ago I glassed in the engine mounting points and had a custom exhaust fabricated so that the exhaust still goes through the prop. I want the boat to be quiet. I fitted the engine and started figuring out the rigging, but the project got pushed to the back burner, since I was enjoying the 64MT. With the help of my daughter Jennifer, I am going to try to complete it before the snow flies this fall. It is a good target, but I have other projects ongoing so it may take until the spring of 2012.

Here is where it stands right now. I removed the engine and tore it down, then sent the barrel (the main mechanical part including the block and rotors) in to A-Spec tuning, a rotary engine shop in Schaumburg Il. A-Spec will tear down the rest of the engine, inspect it, do a very mild street port, and reassemble it. I may have them do the engine management system tuning when it is done as well.

Here are a couple of photos of where it stands right now.

I have decided to sell my 1964 MT and try to finish the 1972 by next summer. I will be advertising it in the spring, but I thought I would throw it out on the site now in case anyone wants to make an offer. There are plenty of photos and a couple of
 video links to it on the site, and I would be happy to answer any questions.

Here are a couple of video links where you can join me for a ride on my 1964 MT on Stone and Spider lake in Manitowish Waters WI

I was surfing another boat web site and I found a discussion about, what else, old boats. They were discussing Cheetah boats and there were several brochure photos. This 1966 looks strikingly similar to MTs of the era to me.

General Mark Twain Discussion / End of year blues
« on: November 09, 2009, 08:11:53 PM »
I had a great summer with the 64 MT. I put a LOT of hours on it and it worked well.

I upgraded it in the spring with a 25 gallon fuel tank, it was welcomed by everyone who used it, the 12 gallon was not sufficient for a run around the lakes. I also installed a water separating fuel filter.
I installed an electric fuel pump in place of the vacuum operated one that was OE on the Merc. The engine would hesitate after idling for long periods or slowly cruising as the filter/separator caused added restriction in the fuel suction line. Not good for skiing. The electric pump fit under the cowl, and other than the slight clicking sound when the ignition is turned on, it is undetectable. I found that the carbs didn\'t need as much adjustment with a constant 3lb fuel pressure. I suggest it for anyone who wants to run an old \"Tower\" as opposed to just showing it.
It\'s nice to have a place to go (here) when the lakes get hard, to dream about next years boating.

Greetings all,
I hope everyone is well!
I began putting the new 25 gallon fuel tank and fuel/water separating filter on the MT last week, but needed a new piece of fill hose to finish. I will have to do that next week.
mkb has given good information on deciphering data plates, I thought I would throw mine out there to give him a challenge. The plate was riveted on originaly, but I removed it and screwed it back on when I restored the boat, so the little ss screws are not original. The spots for capacity information are blank, I thought someone had pained over the information, so I scraped off the black on the \"flotation for\" field and it was blank. I assume they are black so the stamp will show up when it is stamped, like Dymo label maker stock. As I said, before, it is odd that it says  \"Mark Twain Boat Works, Hannibal MO\", instead of Mark Twain marine Industries. I still think it is likely this boat was made by the guys Siebert bought the name and company from in Hannibal before he started production. Any thoughts mkb? Here is the mention of the two guys who were not successful that he bought the company from. I\'m sorry, I just can\'t give it up until I know!


Happy Easter from the \"Bunmaster 2009\"  bunny cake!

General Mark Twain Discussion / 1982 16.9 series 1
« on: April 08, 2009, 11:50:08 PM »
If anyone knows the whereabouts of a 1982 MT 16.9 series 1 or a 82 18.6 series 1 please let me know. I have asked before but had no luck. Sinker (I think) referred me to a dealer site, but it was already sold. I have seen one on ebay in the past 4 years or so, but it was really rough. MKB, could you give me any info on these boats.

General Mark Twain Discussion / Spring preparations
« on: March 16, 2009, 12:11:59 AM »
Greetings Twainers,
Although the water is still very hard up in northern Wisconsin where I do most of my boating, I have started to prepare for the upcoming summer. The decals had become a little faded on the Merc \"tower of power\" that I have on the 64, so I located some new ones and I am in the process of stripping the cowl of the old stickers in preparation for a repaint and new graphics to freshen it up. Everything but the cowl has been repainted, and I was waiting until I located new graphics to do it.

I have also been unsatisfied with the 14 gallon fuel tank in the boat, it is much too small. I ordered a 25 gallon model and a fuel/water separator, that should give it a little better range. With the extra capacity the fuel may sit in the tank for a little while at times, and with ethanol in most fuel now, I am concerned about water phase separation. I have a vent shut off to reduce moisture absorption and I always use fresh fuel, but it has become a concern and I want to minimize potential problems. Relying on an antique engine for everyday use requires good maintenance, and I try to give it the best.  I never intended to use the 64 as a primary ride, but it has grown on the family, and no one mistakes it for someone else\'s boat when they see it. We always get lots of friendly waves from other boaters. The down side is that some of the old Merc parts are hard to find and can be expensive, and the old Merc towers are very thirsty engines. If my boat gas could talk it would say \"three carburetors, no waiting\". I am always amused to think that my car uses less gas to drive the 363 miles to the cottage (10 gallons) than the 15\' boat does to ski for a couple hours or just take a whirlwind tour of the chain. Sometimes I wish for a new Evinrude Etec 150, but so far, no unknown relative has left me in their will. I guess I will just have to keep waiting and hoping. I am afraid it would destroy the classic look of the boat as well

I wish all of you Twainers a happy boating year. We all know we could use a little fun with the problems facing many of us.

General Mark Twain Discussion / WHY MY 64 IS DIFFERENT! probably
« on: January 30, 2009, 07:33:38 PM »
I have been searching for three years to find the origin of my 1964 MT 15\' O/B that I have posted some photos of on the site from time to time, but have been unsuccessful. It is quite different than any of the others I have seen, and it does not appear in the 1964 catalog. It has features such as fiberglass ribs and stringers, cast nosepiece, and fiberglass bucket seats with the easily recognizable MT ribs in them among other things. The capacity plate says it was made in Hannibal MO, and I have searched everywhere, including the Hannibal Chamber of Commerce archives for any information about Mark Twain being located there, with negative results.

I believe the member NOPJM may have answered my question about the boat\'s origin. After reading his post about Siebert buying the company from some guys in Hannibal, it all makes sense.


The boat has many similarities to other Mark Twain boats made in New London and West Frankfort.  I believe they were carried over to the new Mark Twain company under Siebert. It is also interesting that although it is a 64 it has the 70\'s style plastic badge on the side. I thought it may have been put on the boat sometime in the 70\'s, however I have traced it back three owners to the late 60\'s and have spoken to each of them, and they all say they never changed them.

I hope to get a reply from NOPJM so I can talk to him!
