Re: Do you have an outboard for back up propulsion?
At first I wasn't paying attention to your post. I have an Islander-28 with a great little A-4. It is most reliable. An obm doesn't make much sense for my purposes? After mulling over your "proposal" it occurred to me that having an obm that could push the boat if stranded in some remote location might be worth considering. Perhaps if we were leaving for a summer cruise to Newfoundland and wanted a back up motor, would building a removable mount that would hang low enough make sense? Finding the space to store an obm and that mount would be a problem. Probably too big a problem but, being stuck in some fiejord with no engine would be a PITA. If you could lower something down onto the transom and motor away that would be nice. We do have a long shaft, 4 stroke, 7.5 Honda that would probably push the boat at hull speed. Does it make sense to carry something that big as back up? Probably not. It is an interesting idea, thanks.
Carry enough spares for the A-4 instead.
