Re: 27 hp prodrive
you put a big block kawa on it? what is the current diameter of your prop? how many rpms are you turning at what speed. all of this info will help with troubleshooting.

Re: 27 hp prodrive
If you put a FX921V or FX1000V, you need a 12-12.5" diameter prop at minimum. Depending on your setup, these engines have lots of torque.

Re: 27 hp prodrive
Its gonna be trial and error. And it won't compare to the BIG block kawis due to the fact it has a different head design than ours. We have a 6 valve arrangement, yours is 4. Any performance items you do, cam, minkui or EFI, will also be trial and error. You'll have to make most of your parts the same way we did.
