Hey Glen,
Attached are images of my 45SS expansion chamber Mod engine from 2010. The Ski-Doo pipe is large and requires a custom headpipe and mid section to keep it clear of the water.
Note the difference in pipe position from driveway shots to lake: The headpipe and chamber required serious shortening as indicated by test wheel pulls (peak RPM too low). After a year's worth of building, testing, and development, the engine delivered 4.2 MPH better than my best 45SS Mod. It needs additional work - 2more MPH are needed to be competitive in class.
As stated in PM, there is no commercially available expansion chamber for your Tohatsu, and no single solution whatsoever. To achieve your goals, the research, mods, and development need to be done the good old fashioned way - by you!
Good luck with your quest for speed,
Tim
