Re: Tohatsu 40 racing
Dubbel,
You claim you have an old tohatsu M40 C from the 80ies, if your engine is from year 1983 and you have lost 5 hp. you still have a lot more power than the later engines, the first M 40 C engines had a different block terrible for normal use, massive vibration and very noisy.
The noise came from the bigger inletpassages before the port itself (the difference can clearly be seen from outside the block). Theese engines proved to be really fast on any racingboat, even an complete novice could easily win races with thees engines, RPMs near 8000 were common. I had 6 M40Cs sold them all.
