So unfortunately have had personal issues that have kept me from the boat over the last month, and I won't likely have a ton of time before next season to devote to fun stuff...
That said, I had planned to pull the engine to fix an oil leak, replace the steering cable, clean the engine/bilge, etc.
I've had an a/f gauge which more or less stopped working for most of the summer. Eventually started working again, but was reading lean (upper 14's) across all rpms. Prior was very rich (12s) at low speed and richer (11s) at WOT. Nothing changed (looked for an intake leak, vacuum looks ok, idle speed unchanged). Pulled the plugs (below, 2 plugs looked like the close up pics).
Compression on a cold engine was 148-150 on 5 cylinders and 137 on #5. No matter how many times I checked
Didn't change with oil in the cylinder. No time for a leak down test.
Not great but probably nothing I need to do anything about ATM.
