Thread: Hours on a boat... how much is too much?

    OK, I had this discussion with another boater friend of mine. We were trying to determine how many hours would be the equivalent of say 50,000miles on a car, and 100,000 miles on a car.
    The type of engine we're talking about it a mildly built 502, 525, 575, etc. Anybody know? I'm actually kind of amazed I don't know, but I'll be buying another boat this fall, and I want to have a better handle on this. Thanks!

    IMHO, under 300 is low hours. For example, a car with 100,000 miles. Just say the average speed for all them miles was 60mph. That would be 1667 hours. 300 hours would be roughly 19000 miles. Just my thoughts.

    Hours dont matter, it is all about how well everything was maintained. My boat is a 64' and I am sure it has a MILLION hours on it. I have two cars, one has 290+k and the other has 180+k and both run very well.

    My suburban has 1450 hours with 50K miles... the 2001+ models have an engine hour meter on them. Of course 1450 hours on a car might be like 800 hours on a boat... because most of the time you are at higher throttle settings in a boat.

    ABOUT 1600 HOURS OF RUN TIME WOULD EQUAL 100,100 MILES JUST A ROUGH GUESS

    Not according to my suburban's hourmeter.

    it's hard to compare miles on a car to hours on a boat. How many times do you run your car at 3,500 RPM?? Not often and when you do it's only for a short burst.
    Then you hop in your boat and don't think twice about blasting across the lake at 4,000 + rpm on a 100+ degree day (with a poorly vented engine hatch!).
    Boat engines work MUCH harder if you ask me.

    Yes I wholeheartedly agree. That's why I said my 1500+ hours on the boat is probably equal to between 7 and 800 on a boat... due to the higher engine speeds and loads. That'd make 1500 hours like 100,000 miles on a car or so... (Is that what you were saying Silverwing... if so... I misunderstood you... sorry).

    I have a couple freinds that ski competition. Both of their boats
    have 1200+ hrs on them.
    Thier boats are less than 5 years old.
    Their boats are in great shape because they maintain them.
    That's the most important thing is how well the boat has been
    maintained.
    300 hrs in nothing. My boat is appoaching 300 hrs. And I figure
    it's just broken in. The motor is just loosening up.
