Boat is a Sea Ray Sundancer 240 and my old 5.0 EFI (Throttle Body Inj) is shot. Looking to repower with a complete engine package from Mercury. Down to two options:
1. Reman 357 Bravo 4V carbed, 325 HP (at crank) and 3 year warranty from Mercury
2. CPO 350 MAG MPI, 300 HP (at prop) - same warranty as above I think.
I am concerned about the added fuel consumption of the carb motor. I had TBI on my old motor and it still sucked gas. Maybe a tired motor on a heavy boat? Will the carb motor really drink much more gas vs the MPI?? Also, will the driveability / startups be that much better with the MPI?? I have never had carb before on a boat. I only use my boat for about 50 hours a year....Cost difference between the two motors is apprx $1600. Any thoughts appreciated.
