Just want to say thank you for all the input on this thread. I am currently trying to decide whether I should repower my current boat or buy another boat, and a Scarab 26 has been on my wishlist for some years. The Scarab 26 that I wanted to check out has been sold, so I didn't even get to see it and try it. But I must admit I am disappointed to learn that the engine mounts are not and can not be through bolted due to the lack of real stringers. I didn't expect that from Scarab.
Thanks again for the input.
