Well I got mine going strong as ever again, with the 215 prop. I will try other props with the boat tuned for the 215. See I havent had a 215 for about 10 days now, I just got one yesterday and all is running good now. Only problem I had was water was a little choppy and the tuned pipe blew apart at the coupler so boat died, but boat got its full 15min float test and past. So tomorrow will run again and hope all is as good as today. Can anyone recommend a good fastener for the exhaust coupler , the zip ties just dont wanna cut it.

p.s. Tried a x637 and no good, it is smaller than the 215 also. I will try the x637 again tomorrow and see how it goes.
The best zip ties I have found are; Thomas&Betts, cat. no. TY524M These are bullet proof, metal tang,40lbs.test,
185F temp. from elec. supplier. There are some others, ask Chris Wood, Panduit I believe?
