I just had my 2001 90 H.P. Evinrude rebuilt. The mechanic can only get a max of 4500 RPM's out of it. He said he lowered the pitch of the prop and raised the motor and now has it up to 5,000 RPM's but cavitates and I will have to back off of it.
I know this is not right and I'm asking if anyone has any suggestions. BTW, this is on a 20 ft pontoon boat.
