Mart I thought the idea of a WTC pipe was to have in the centre of the hull, testing should be interesting!

As you know i lengthened the pipe with a sleeve this was the best fit so went with it rather than bend anything where the pipe ended up makes no odds in this situation.Im confident she will be in the 30+ region with this setup stands to reason, i had the stock motor with can muffler in my wooden hull which weighed 16-17 lb  and speed was arround 28-30 mph depending on conditions this one weighs only 12.1 lb  ok2.

If you heat the inside of the bend where it enters the tune pipe to a cherry red you can straighten the bend easily to centre the pipe it will blue the chrome but would polish out.

Yup i know i could bend it if i wanted but like i said it doesnt really matter in fact it looks better  to me not been in the centre.If id had it bend more central the pipe was too close to the shroud and i didnt want to add too much length to the bend and make the pipe any longer than it need be,id say its quite a bit shorter than yours as i only added a 1 1/2" sleeve and the gap would have been maybe 3/4" at most.I used the wtc pipe because its what i had and i thought a slightly longer pipe would suit the motor better but i didnt want to go any longer than i needed to for obvious reasons.Seems to have good power and quite responsive so cant wait to try it out on the water.The boat should balance better with the pipe on the left anyway as the radio box is going on the oposite side above the stringer  ok2.As i say this ones just a play boat but i think some might be a little surprised how well it will run.Next one i do ill maybe go for a hotter setup we shall see.
