The Beta 38 would be a fine choice for a motor sailor such as the Fisher 30. Use a lower ratio gear and as large a prop as practical. 17" - 18" dia would be appropriate. You will need a right hand propeller.
This install has been done at least once before. If you send a message to my email I will try to locate the photos and email them back to you.

Thanks for this. Just sent you an email as suggested. I appreciate any photos or further thoughts on a Beta 38 installation on a Fisher 30 Northeaster. Rick
