Replacing Yanmar 1GM10 Saildrive with 2YM15C Saildrive.

[ianwoods]

I wonder if readers could give me guidance on this matter.
I currently have a good 1GM10 saildrive dating from 1992 but would like more power and am therefore going to replace it.
Can I mate up the 2YM15 with the SD20 leg of the 1GM10 without any adaptions?
Will the 2YM15 fit onto the existing engine mounts on the glassed in plinth on which the 1GM sits?
Have any readers done this conversion? Please let me know of any pitfalls.
Where is the best place to get a 2YM15 at a sensible/discounted price?
Many thanks for all who care to respond. Ian.

Speak to Dickies of Bangor, or your local Yanmar agent. They are likely to know how the units differ, if they do.
