    Johnson 9.5 leaves oil slick in barrel after running

    I been tuning on my 1970 9.5 and started noticing quite a bit of oil floating around in the barrel after i shut it down. Do you think this is caused by a bad lower crank seal? Any other suggestions?

    Mercruiser 165 key switch wiring?

    I have a 1970 merc 165 inline 6 and was wondering if someone could tell me what wires go where on the back of the key switch. Is it a 3 or 4 prong switch?

    What Prop is next

    I had a stock aluminum 21 pitch on my 115 Mariner and caught a couple rocks. So while that was being fixed I put on a Ballistic 21 pitch stainless prop and now I run too many Rpm's.

    Ok, all or most all of the oil leaked out of my cylinder due to a broken fill plug. Now i read the service manual on how to bleed it and it doesn't help much. The only way i can get the motor to go up is by lifting it after i open the manual release valve which i think just lets air in. It will...

    '94 mariner 115 squeals at idle

    Was on the river this past weekend, stopped for a few minutes and after i refired the engine the thing squeals when it idles and when your trolling. It still runs fine and pulls good. Still pissing water like it should. To me it sounds like a bearing. Almost like when a alternator goes out on a...
