I have very limited experience with Yamaha FX140 PWC.  I'll take a shot at the question though.  Your 7500 rpm sounds just fine, however that would yield a lot more speed than 37mph.  I have scene this problem once before.  Impeller clearances were perfect and everything about the pump looked fine.  However, it had excessive cavitation and pump slip.  There is a seal kit available for the pump unit and ride plates.  It required a little bit of time to install, but afterwards the FX ran great.  Best I remember, it ran around 70?????  I don't remember what top end was before we made the repairs, but it was not good.  I just saw that customer the other day, and remember his name.  I will look in his file and get my research notes and read through them.  If you want, you can call me later today.  I am at Lake Martin Shop.  256-825-3388.  I will share that information with you.

Respectfully,
Steve
