Yep, there would be shorepower and those are some options to consider. Thanks.
I think the bigger issue is simply whether or not the engine as a whole is worth the risk given that it is raw water and has spent its life in saltwater. Especially since on a boat of this vintage, an engine repair/replacement is such a large proportion of the overall cost/financial worth of the boat. I suppose the best that can be done is to have a diesel survey and take a chance if I want to go with this boat.
As mentioned, in a perfect world I would prefer a different engine and it has given me enough pause to consider buying other boats with newer engines. Then I have to keep reminding myself I'm not simply looking to buy an engine.
