I have an 1978 Century 4000, 21' Cuddy, 351, OMC outdrive, electromatic gearcases, boat is a 1978, outdrive a 1977, why, I do not know, it has the 5 bolts on the exhaust housing cover and the pin to hold the prop, with the cotter pin for holding the plastic cone on. It has recently been jumping out of gear, foward, not reverse. If I hold down on the throttle handle it won't, but the minute I let up on it, out of gear it goes. RPM's went to the moon a couple of times, please help.
Thank you.
