I have a 1993 Evinrude 175 hp Intruder that has what I've been told as a piston slap due to a piston skirt being broken. It has 90 psi on 5 cylinders but has 80psi on the lower right .
Model E175GLETR. Ser # G 03192153
Boat has lost some power and really really rattles bad when trimmed up...
Hi Guys.
I'm afraid I know the answer but here goes.
Motor runs good as long as it's under a load. If I trim up around 4k rpm or above and get on pad she rattles bad. If I tuck the motor back under it quits.
Compression is 90-93 psi on 5 cylinders and 80 on the port side bottom.
I'm thinking...
