Outside of breaking down the motor, how would you suggest I check it? She still fires up right away, idles as normal, revs fine. Only thing is when I'm running it has a bit more vibration (think the prop has a small bend in it) and the cavitation plate is cracked. After the wreck we still fished for 2 days, and a few more days before I cut the boat up. I'm not sure if the motor will last 100 years, but even if I need to rebuild the power head it will cost less then a new motor.
