Guys I'm looking at a 99 boat w/ 500efi's w/ 300hrs. Seems like everything I read says the motors need refreshing about that time. Can anyone give a ball park figure as to what that normally runs $$? The motors would have to be pulled obviously. And also at what point is it time to redo the bellows and what does that normally run$$? Again I just need ballpark figures, I'm in Arkansas near LOTO etc. Thanks

Top ends at 300 hours - bellows should have already been done. Prices will vary depending on what is needed. Did top ends on one 575sci - new head gaskets, bolts all new valves springs retainers etc with machine shop time for about 3000.00. I supplied the labor. Had a very reputable marine tech - Dave at MDG , perform the assembly and parts purchase.

Should need top ends only refreshed. Prob 3-4k per engine depending on what parts are needed.

Can do top in boat.

to the OP, are you a mechanic, are you getting the hours from a scanner ?

No sir. The seller listed the motors at 300 hrs.

Verify hours with a scanner. I'd pull engines to do the top ends.

I've done top ends on 2 different single engine boats. One in boat and one with taking the engine out.
I would never do one in the boat again and would never attempt it with twins.

If you need some help let me know, what make is the boat...........where are you in AR kan sa

Edit: dont buy anything without scanning the pcm's, they tell all

Thank You very much for that offer!! The boat is a 99 Fountain 32 Fever, and I'm in Rogers/Bentonville
