1982 Glastron Carlson OMC to LS1 SWAP

Hello, I am brand new here and somewhat new to the boating world. I have a 1982 Glastron Carlson C-537 with a 3.8 OMC/800 Stinger. As these are becoming worn and more difficult to get parts for I would like to replace both units with something to the effect of an LS1 with a Volvo drive. Does anyone know anybody who does this kind of work and pull it off to ensure reliability? Is this practical or should I be looking at alternative options? Thanks Kyle.

 

A friend had one of these,years ago.

There may be Glastron guys here,but there is a Glastron owner's website and likely you'll find someone there who's done something similar or will advise of strengthening,if it'll even fit, and the weights.
I suspect the LSI will weigh similar to the old 6
It should really fly..

 

The LS1 is a bolt in swap on small block bell housings, so you're not going to have an issue. The Volvo (as well as everyone else) has been using the second gen and Vortec blocks since the mid 90's so not an issue. You can still get the first gen small block in these setups as well, so be specific as second gen and Vortec blocks don't have mechanical pump provisions, which is a great improvement, as they don't leak or steal power from the cam.
