Re: 115 Mercury Foaming
Foaming at the port huh? I'd say it had rabies
<br />Sorry, I couldn't resist. Gear lube can leak-past the pump's diriveshaft and shifter seals. And in theory, yes, it could precievably mix with coolant water expelled in the exaust and foam-up.<br />Many times and engine can dump the contenst of the carbs and recirculator system into the block. Maybee some rain water got into it?<br />But I would drain/inspect the L/U, and if clean,refill with new vent/fill screw gaskets, as SoS sugjested..<br />Also, if clean, check the compression every cylinder, as it could have a leaking head or exaust port plate gasket. Check the plugs, as a brand new looking one amounst normal looking ones, would indicate a steam-cleaned plug (ungood).<br />If the all plugs look normal, as opposed to having one or two that looked like they havent been installed yet---and the compression test passes on all jugs--and the L/U lube looked clean, you can safely decide your motor is ready to rock.<br />Good luck on all counts.
