Many marine mechanics recommend disconnecting the oil injection on those older Mercs and mixing 50:1. Apparently the plastic gears inside the crankcase like to strip out with age, starving the engine of oil and making a heavy anchor.

Shouldn’t it be in gear before removing?

What is the process for the shift shaft removal. Does it just pop right off somehow? Hopefully your still around on here I know this was 4 years ago.

Looks like a bunch of rust on it sitting on the stand? Came apart pretty straight forward. Inside of engine compartment looks good. Was the lower unit froze up. Didn't have any lower unit lube just a bit of water came out

Oh I cut out the footage of it draining. Granted, it didn't seem like there was much in there, more came out than made it to video. And no, lower was okay. Powerhead is pretty junk. I thought 2 of the cylinders were bad, nope; 5!

This is a shade tree mech. If you don't know already how to do this, just trust your mechanic. This is an 85 Black Max. Shits bullet proof. The top end probably had water injection, and his dumb ass was incapable of installing a full engine gasket set. Mine runs like a surprised hominid. 😮
