Dropped sponson sport40 roundnose project

[P THOMAS]

Here is a project that I have had for a long time and got it out to finish it up. It is a MTO hull that I cut the deck to make it a dropped sponson boat. I used an engine well out of my 40 roundnose Karlesen boat so i dont have to use wood engine rails. A little chopping and cutting and it fits ok, i added the engine mount T nuts so its ready for the motor mounts. started to fit the cowling and cut out the front of the engine well for a fuel tank to fit in the front.

It will be thru the bottom of the hull. The MTO is a longer boat anyway

Lookin' good Phil. Did you get tired of seeing all those SS45s out there and decide to take a walk on the wild side with "Brand X" ??? Har, Har !!! Was this one from after Doug made the sponson changes? CHEERS !!! Bob

Probaly like the U8 hull, what were the sponson changes? This one looks good as to angles.

I have to build one of the SSP45 too this year to race. My 40 roundnose Bardahl won the Indy Masters last year.

I just cut the deck and added a wood spacer then glassed it in under the deck.

"......what were the sponson changes?"

Hey Phil,

Just remembered your statement. Non - Thomas hull boats are "Brand X" - Har, Har !!!

Blue hull was the original sponson bottom, After Doug bought the K&H molds he changed the bottom adding the recovery pads shown on unfinished hull.

According to a Friend - the hulls were always fast down the straight, but would do an inside snap roll if pushed hard into a turn. He added stumble blocks to his, and said MTO did same later on and changed the bottom molds. CHEERS !!! Bob

 

[P THOMAS]

That epoxy hull is like the one I have, it looked good to me.

Yea it is a BRAND X but with Phil Thomas changes, just cant leave something alone.

It was a cold case project for a couple years, should be fun to setup and run .

 

[Dasboatman]

Hey Phil,

Good. The better of the two. It will be good to see another MTO on the water again.

Is that the motor mount you're going to use or just an alignment fixture. Radio box in front or behind engine?

Har, Har !!! I can't leave something alone either. There have been two SS45 through my shop - neither left even close to stock. One was the old hull bottom prior to belly pan fiasco, second was with the new bottom mold. First one ran very well, second is destined to become a Hangar Queen I believe - still hasn't seen it's first test hop. My efforts to get Sport 40 here in Houston going the past 10 years has been a miserable failure. Little to no nitro interest. CHEERS !!! Bob

Looking great Phil

 

[P THOMAS]

Thanks, yes Bob that mount is just to be sure it stays 5 inches wide. I plan to use a two piece Speedmaster hydro mount.

YES i got all the hardware in from Speedmaster. Going to use a Speedmaster hydro mount and offset the motor to the right to make more room for the tunned pipe and radio box. Its been on the shelf I may work on it some today.

Hi Phil.......We used to have a guy here in D3 that altered, I believe an Aeromarine Sport 40 to make it into one of the newer (at the time) pickle forked Scales, rear wing and all, and it really ran good. I don't recall which Scale it was, but I really liked the way it looked. BTW thanks for your input regarding fuel proof clear coat in a spray can. I tested all of the standard Rustoleum (colors) on test strips, and after sufficient drying time, 50% racing fuel sat on it for days, and NO problem at all. However, the clear coat that is part of that same line is useless, and as a matter of fact regular rubbing alcohol takes it right off! Hi everyone!

 

[P THOMAS]

Got some more work done on the roundnose project. The motor mount is offset to the right side to make more room for the tunned pipe and radio box, I ran the shaft straight back so the strut is offset the same. there are more pictures in the Album http://www.intlwaters.com/index.php?app=gallery&image=11450
