I like that small hole idea – I may fill the hole with a tiny grease. fitting. I use a Dremel wire brush to clean the rust off the threads that I can reach. (There flexible shaft lets you get in tight places better and, as a bonus, the motor runs at a lower tempriture.) What has given me problems is the screw driver handle on the 3.3 HP Evinrude Sportwin with the fuel gage, and the 7.5 HP neutral clutch Fleetwin. . .
