Merc. 800 SC
Ok, so I went boat shopping recently. I came across a boat with rebuilt Merc 800 SC's (30 hrs).
Does anyone know what the reliability of these motors are. I understand they have a great bottom end (572's) low boost etc.
What is the time between rebuilds? What are some of your experiences?

I have heard the dyno tests on these were around 700 hp. The valve train is the same as the 600sc, (hydraulic lifters) which will last without help unlike the 900sc. You don't have an intercooler to leak. So if you keep good gas in it you could get 500 hrs+, if it was rebuilt properly.

The motors were rebuilt with SuperChillers installed, so I am figuring it would be making 750 - 800 hp at the prop?
500 hrs. that seems pretty good? What does everyone else think?

If 500 hrs. is an honest number, I may be able to live with that. I usually put about 50 - 75 hrs. my boat per season. This is 50-75 hrs of cruising, with short WOT runs once a month or so.
