Regarding it running hot- Mine had a filthy triangular baffle Screen in the water discharge that prevented the water from discharging properly. I slid it out (and left it out) and now it seems to run cool.
Found the part numbers, 0321467 from OMC, or 18-2060 from Sierra, about a $5 difference per seal.
When I was able to get it running it stayed cool. I disassembled everything and blew out the tower and powerhead, and took apart the waterpump and re-checked everything. Nothing I could tell came out when I blew everything out with an air hose, pump impeller still looked good. I dunno, what was causing the heat issue, but it seems to be gone now.
Well… I took the powerhead off and changed the seals. Now she doesn’t run.
I didn’t disassemble any of the ignition plate. Just pulled the seals and re-installed ’em. When I pulled the plate off I cleaned the mounting ring of old grease and applied some new grease.
Anyone think of anything weird I might’ve done? About the only thing I can think of is that the grease might be acting as an insulator between the mount and the ignition ring, preventing a good electrical circuit.
I need to get a spark tester. It’s acting like it’s got at least a partial spark (you know how you can tell that it sort of wants to turn over mid-pull?) I’ll check the points again, but I didn’t remove the plug wires from the plugs. I didn’t actually remove anything but those 4 screws that hold it to the the hold-down ring and the linkage on the throttle arm.
I can’t see how the fuel and compression would change.
