Hello All! I have a 98 Sundancer 330 with two bad engines. They were both 7.4 MPI's. I will be operating in San Diego Mission Bay (which is salt water) 99% of the time. Very short trips of only a few miles from the slip to cruises around the Bay. Maybe 25-50 miles max on a real long weekend with lots of movement. There will be 1-2 to annual trips to Catalina but above and beyond that it's just going to be in Mission Bay, which is mostly no wake btw. I am considering swapping to Gen IV 454's with carburetors. I have heard both good and bad things about the 7.4 MPIs BUT it seems like they really don't like salt water and I am finding that Gen VI big block parts a hard to find fast and cheap and I need fast at the moment. I do all my own work and I can definitely go through the existing EFI systems and get them going again but I would HATE to spend all that time and money to have constant issues. Having a strong hunch towards going with the old Thunderbolt ignition system and some simple Edelbrock carburetors. I know EFI is safer on an inboard but I am pretty meticulous about maintenance and I keep my eyes on things. Am I crazy for wanting to go old school?
