"I grew up running 25+ year old Evinrudes etc on freshwater lakes and rivers. Given the weight difference between 2 stroke and 4 stroke, I'd dearly love to keep my '04 9.8 running forever. We didnt do much special to those old motors, just yearly maintenance, fix'em when they broke.
But...is there anything I can do to keep this motor running since its essentially irreplaceable?
1. Regular freshwater flushing (I use it in salt)
2. Annual maintenance
3. Keep it from getting stolen
