Upper Engine Mounts on 2001 Mariner 200hp

Looking for some advice

I have just lifted my Mariner 200hp - 2001 off the back of my rib to do some repairs on the transom and repaint. I was planning to have the engine back on in the next couple of weeks but now having chance to inspect the trim tilt/mounts I am a little apprehensive about rushing into the reinstallation stage.

The upper engine mount is badly corroded to the point that the bolt heads have disintegrated and there is some side to side/forward back play on the mount.

I cannot find any schematics of this mount in any of my manuals but it looks like a major job to get into them?

Will I need to take the power head off or is there a work around?

not too bad a job - powerhead off, then you need to replace the engine mounts (as a pair) - about 60 each - but also the powerhead gasket and exhaust gasket. Just take it easy undoing all the fiddly bolts that hold the powerhead and leg cowlings on they snap for a pasttime. Only took me a few hours to strip and rebuild both my mariner 40's recently - admittedly lighter engines. The hardest job was carefully cleaning away all of the old gasket material without scoring the mating surfaces. Pefect job now, you don't want those mounts to fail completely!
