I have a Nissan 5 hp outboard and the anticavitation plate (as they call it) is vertically located in the fin above the foot of the motor. Those little muffs you buy to flush a motor out of water will not fit because it goes straight up into the motor. The exit for the flushing water is higher up as well. It is a 2-stroke with a forced water
pump for cooling. Is there any way to flush this. Everyone I know insist it must be flushed after each use or the saltwater will corrode the parts. The previous owner denies ever doing anything to flush it. Only tilting it up and all the water flowed out.
