Thanks .

I started with this question because I have been using a British Seagull with a long shaft, but have a 15 hp and a 9.9 hp outboards that I'm interested in using.

The outboard well on Thistle Dew has been modified at some point and I am wondering where the top of the transom was originally, and if cavitation is a problem or just an inconvenience with the short shafts.

Does any one know the average distance from the top of the transon to the water?
