my brother finally found a boat to look at it has 900 hours on ether a Chevy 350 of a ford 351 not sure which one our uncle is telling him that 900 hours on a boat motor is way to many and the motor is probably ready to die or super worn out i told him since he rely likes the boat and the price is right he should go for it and run the motor till it needs a rebuild then just rebuild it. any thoughts whats the equivalent to 900 hours on a boat to miles on a car

At 60mph, 900 hours is 54,000 miles. But a boat under considerably more stress than a car. The answer depends on maintenance and use. There's no reason why a boat engine can't go twice that, but some people (myself included) have killed them in less than 1 hour.

Do a compression and leak down test. Chances are, if it made it 900 hours, it'll make it 100 more, which is a lot of time on the water. I probably put 2 hours a day on my engine, and do 8 weekends per year...so it would take me 6 years to get to 100 hours. Considering that
It'll probably get around 3-4mpg at 40mph, 100 hours (4,000 miles) will cost you $3500 in fuel. A basic engine rebuild is cheaper than that.

900 hours on a marine engine equates to roughly 125,000 miles.

A typical marine engine properly maintained rarely runs much past 1500 hours...

It is all bullshit though unless you know what maintenance was performed and when.

That being said, with 900 hours, plan on it being at least 75% through it's life expectancy, I would rather buy a boat that had some hours on it than just sat in some dudes garage for 15 years....

If the deal is right, I say go for it...
