what does everyone think of a 2000 502 mag mpi with 150 hrs. bone stock

They came in a variety of boats.

.

They are black.

502 Mags are great engines. Very reliable if well maintained.

Send it on over.

yeah but i think the 350s are too, how can you tell em apart, they both have 8 cylinders and a carb thingy on top

Actually RM, it's EFI.lol No carb thingy.

The 502 Mag is an excellent engine. Pretty tame piece that will run a LONG time. That year is a much later model with much better parts, like cool fuel, Mefi 3, serpentine accessories, etc. Tough to go wrong with it as long as it checks out.

They have pistons the size of Folgers coffee can's



Clogged/dirty injectors will cause the engine to lean out.

Stupid vent in VST tank cost $86 fora piece of rubber, and when it fails, it washes down #8, and thins out your engine oil.

They have a tendency to vapor lock witch is embarrassing when you idle threw a long channel in the heat, hit the sticks at the end and the engine stalls out. Skanks now leave your boat and get on a fountain

Top end is recommended around 500hrs I believe. They CAN blow head gaskets.

Heads weigh 75+ lbs, so do the exhaust manifolds.

Very reliable engine, and saying 502 mag has a catchy tune

You can lay on top of the engine in comfort (to a point) to work on impeller, plugs, wires.
