Pelican, I believe you're right - it may be a TBI.. its a GM block. Although it does say Electronic Fuel Injection on the engine, so I'm not sure.
Nausetblue, the model I'm looking at is a straight inboard, not at i/o. The engine is under the console, so the stern of the boat is all clear. Good point tho about those io's sitting in a wet bilge. I'm expecting a better ride, but slightly less fuel economy from the inboard vs the 4 stroke ob. Sea trials next weekend, I'll pass along results.
