    1176cc 66V motor question

    Would anyone know what the max rpm's that the 1176cc 66V engine can handle. I guess Yamaha would know that, but thought I would try again here.

    Thanks

    Just curious what these motors (stock) can handle in terms of max RPM's without tearing themselves to pieces.... I have asked that question before and was never able to get an answer.....

    thanks!

    due to the stock pipe limits and rev limits about 7450... triple piped boats can spin up to 8000 no problem

    others have spun them a little higher

    its always recommended to have a crank welded if more than stock
