"Hi there, I have a question regarding the saildrive on the boat I sail (Mumm 36). Engine is a Yanmar 2GM20C (I think, no idea about the saildrive).
When we removed the folding prop to replace the anode we were greeted with the following (see pic)
http://www.marineengine.com/discus/messages/12498/149930.jpg
The bolt thread at the end of the splined shaft has been sheared (previous person didn't realise the nut and bolt had been pinned!! Anyway, it now needs a new splined shaft + assiciated nuts, bolts and pins.
We were going to remove this today however we have no manual or diagrams.
Can anyone tell me what to expect when I split the saildrive?
Is there a thrust bearing?
Is it full of oil or greased?
Will it come apart easily or does it need special tools?
If anyone has a drawing they can post it'd be really useful.
Cheers
Chris"
