How many hours are too many?

Re: How many hours are too many?

If I couldnt get more than a thousand hours on a mill I would drive my truck through the dealers lobby with the boat attached.

my 4.3 has 800 hrs and I personally know of a bunch more with 1000+ (heads still original)... I don't thinks they should require new heads at under 500 if properly maintained these along with 5.7's are likely the most durable and popular marine engines out there. That's my 2 cents worth anyway

We have run inboards for 7000 hrs

wow - for real? commercial use I guess.
7000 hours would be $180,000 worth of gas through my runabout

If I could only get 500 hours on a gas engine before rebuild/overhaul, there's no way I would buy it.

I have 575 hrs on 2 7.4L Mercruisers and they are as strong as ever. It's all in how you treat them and maintain them.

Re: How many hours are too many?

Hi all,

I'd appreciate your advice. I'm seriously considering a 99 1850 Bayliner Capri, with a 4.3 Mercruiser. The boat is in excellent condition, but the engine has 424 hours on it. This seems rather high to me from my limited knowledge / research. It has a full 6 monthly service history, and just had a fairly major service, involving replacing cylinder head. I'm confident it has been well looked after, but the seller is not offering any concession on the price in light of what I think are high hours. Should I be wary of an engine with this much use? Thanks in advance. Chris

Too many is relative to how well it was kept up. 100 hours and beating it to death without maintaining could be a disaster.
