Dream Boat

[abl1111]

I have a 1975 23' Tsunami w/ a new 300HP mercruiser, fresh water cooled w/ a bravo III ( and a 24 pitch prop ) - it 'boogies w/ stu' and is powerful too; clean and efficient.

That is my recommendation. I am not that familiar w/ a diesel set-up for a 23', but I would have to think that that would be the best option, if $$$ were not an issue. Diesels are extremely durable and efficient - however when things break - it gets expensive for parts and labor.
