Yamaha Outboard Gearcase Disassembly and Diagnosis 4HP 4-Stroke 

Nothing broken in gears. Why not disassemble and clean and lube and reassemble?

A couple of new bearings from Yamaha are only about $24 each. Oil seals maybe 5 bucks each. I rebuilt mine a few months ago. It did have oil in it but was mixed with water which ruined the bearings.

Can I open my engine like that or will all the oil drip out

Probably the mount break damage was the same thing that bent all the prop blades

As far as me, I'd replace with all brand new, if I wanted to keep the engine. It looks like a 2 stroke..

4 stroke,or 2 stroke????

This is a 2 stroke dude

Good videos, however this is a 2 stroke not 4 stroke
