Evinrude Mate 2

[need2bike]

Hey, I’m pretty new to boating and outboard engines. I have a 1973 Evinrude 2302 Mate 2. It was free and I have no idea when it ran last. It was seized so I’ve subsequently taken it apart…except for the two pieces that were seized together: the bearing housing assembly and the crankshaft. I’ve tried to lubricate it, I’ve tapped it lightly with a hammer, and I really don’t know whether the struggle to get them apart is worth it meaning will either part still be useable if I separate them. My rough calculation to replace most of the gaskets, the lower unit seals and impeller, upper crankshaft seal, and piston rings is about $150. New used crankshaft and bearing housing would be another $100 plus. I guess I’m asking have others had this problem with those two seized parts and did anyone have success? If I decide I’m better off to sell the parts than rebuild is there a market for these parts? Maybe I also need encouragement to just throw caution and cash to the wind and try to resurrect it. The schematics on Boats.net “crankshaft and piston diagram” parts are 10 and 16 that can not be separated.

Thanks

I looked at the parts diagram, 10 is the crankshaft, 16 the lower crankcase bearing housing. If all were OK these parts should just slide apart. Since yours are apparently very stuck, I suspect serious rust issues exist. The bearings and crankshaft will be ruined and not salvageable. There should be visible evidence of rust and corrosion, is there?

Here are three thoughts:

1. You can make your own gaskets by cutting them out of gasket paper with the help of hollow punches.  Depending on how many gaskets you need, this could be a cheaper option than buying pre-made gaskets.
2. I don’t know what lubricants you’re using so you may already know this but specific oils (called penetrating oils) are made for separating seized parts.
3. Unless there is something obviously wrong with the current piston rings, they can probably be reused to save you some money.
