"1997 150 yamaha salt water series, problem just started. Motor runs great until I go into the wake of another boat. Motor begins to shake with a high pitch sound. oil indicators on dash start to flash. I back off throttle to slow boat, and motor runs fine again in calm water until next waves.
Moter is trimmed down or slightly up."
