Need to shorten that pipe and get some revs in her. Then she'll fly. Also makes the pipe a bit quieter.

Hesco she is running great feel like sharing a few set up tips with everyone pipe length prop and anything done to your engine so far on mine i have shortened the rudder about an inch opened up the exhaust headder and am running a 443 prop think the best prop was an 445 but i tend to run in rougher watter so i like the smaller prop

RE: Thunder Cat 31
Hey everyone been a while since I've been on here. Decided to get the TC out a few weeks ago to see if it'd still run. Fired right up with no problems. Was able to get some good runs in a few weekends ago and got it GPS'd with my iphone. Right at 37mph so I'm thinking close to 40mph without the added weight to the phone.
One thing I did notice, and I think I was having this problem before I put it away last time, is that it is taking on large amounts of water. I've ordered a few autobailers to put it some maybe those will help.
Now that the weather is getting nice here in OK I hope to start running it more. My plans for it this fall are
install autobailers
trim rudder
repair a few hairline cracks and repaint boat
Polish engine? maybe
Figure out a better way to seal the radio box. Taking all the little screws out each time drives me crazy.
Well thats it for now. Good to see theres still a few people active around here!

This was boat project started by a fellow who died shortly after he sent it to the shop to customize.This fall will just be a breakin period for the motor then work it over this winter to have it ready for some good running in the spring.Hopefully the .45 will really push it.

I wouldn`t be surprised if that TC will blow all others away. I made it to 51 miles with only a .27 engine so this one should be faster if everything adjusted properly

RE: Thunder Cat 31
Need some input...ok.. bought a TC that had been customized,never been in water,inside has been epoxy reinforced...45 Axe/Rossi marine..air inlets cut out,air outlets cut out..rudder trimmed down as was the strut,gonna run 20%nitro for break in since I already have some.My question is props...it came with a Prather 215 which I feel is a bit small..I would like to get 2-3 more before I go run so I can experiment..so which 2-3 do you all think would be in the best range??

Prather 220 great to break in with. 240 size decreased back cut a whoooole lot and made so thin that you can see through it sharp enough to shave with and she will hall a#^e like you wont believe. Wish i can find the bugger that took mine. But I'll make another

RE: Thunder Cat 31
Got some autobailers installed the other day and they came out pretty good. Just setting it in the pool they work really well.
Also started to paint a few things and got a little carried away. Painted the header and exhuast with some high heat black along with the engine mounts. Then Primered the inside of the hull. Looks much cleaner now.
I bought a can of this stuff called Plastidip at home depot the other day. It's like a rubberized spray paint coating that you can peel off. Decided to paint the hull with it! The finish isn't quite a smooth as I was expecting but I didn't do the best job spraying it either. Will be interesting to see how it affects it on the water. And the best thing is if I don't like it you can peel it right off.

RE: Thunder Cat 31
Did shorten pipe some as I also thought was a bit long.Installed pressure nipple at the"fat"of the pipe,installed fuel filter and filter on pressure line to prevent crap in the tank.Did fire it(with water running through the head,SOUNDS GREAT!!! This .45 has some gump!!! Gonna try a quick run Sat...next ?????? Should I tilt the strut down a tad since the pipe sits so high to balance getting on plane,keepin the nose down a bit??

Nope. First see how it runs. Negative trim on a cat is recipe for submarine tendencies. Rather keep the strut square and drop in vertical a bit. Will get the nose down quickly. And ditch the filter on the pressure line. Keep one on the fuel line.
