I'm getting ready to start some repair on my '89 Force 85. I have a manual in case; but are there any strange things I might come up with; seems kind of straight forward: cotter key;6 bolts; 1 hidden in the exhaust; should come off? Also; any suggestions on taking the thermostat screws out without them snapping off? Have some other stuff I want to do too: overheat sensor; and change LU grease. Any suggestions would be appreciated.RF
