A carburetor will do all that and not quit working.
Nowdays people think carbs are junk and EFI is a god,not the case.

After just a quick search it seems most of the problems were with the EFI when they first came out, is this true that maybe after about 1999 they seem to have less problems?
thanks RB

nope....like said before, search vapor lock, sooted transom....

Old early Merc EFI systems were a decade or more behind in technology WHEN THEY WERE NEW! The old factory systems can't hold a candle to the new aftermarket systems. I love my Holley HP EFI self tuning system. Set it up correctly with a return regulator and it will never vapor lock. The old Merc systems used a single large fuel rail that were returnless and just would bake on top of the motor from the latent heat when you shut them off. You can get good aftermarket systems for about the price some people think their take off Merc systems are worth.

modify the merc system to return to the tank and most problems are solved.

It is a trade off. EFI more reliable but when it needs attention it is a nightmare with dozens of sensors/etc that could be causing trouble. 10% more power. A carb and one wire distributor is nice, nothing is simpler, you can draw the entire fuel and electrical system from memory in seconds. EFI is wildly more complex.

Carbs have made more power in every comparison i've seen. The one benefit to EFI I've seen is that it can tame larger cams and help them idle at lower speeds.

no warm up.I start and go at the dock.

With injectors above stacks?

The stock mpi worked fine on my ProCharged 502. It did have a return to tank fuel line setup. That said it always fired right up. With my new build this winter I'm upgrading to the Holley HP EFI but ide keep the old mpi long before ide run a carb. This is an expensive boat though, if I had a small "hot rod" jet boat then a carb might be OK.. Just my opinions.
