Hrs. to mileage?

Does anyone know how to convert the boat hrs. to a mileage number. I was never good in math class ;).

Post this under the wakeboard thread. Or do a search I just posted one of these.

I read in waterski mag its 10hrs = 1000mi but due to the fact everyone uses there boat differently, that is a very inaccurate ratio.

700 hours on my silverado and that is 25700 miles

I don't think it can be done accurately. Boats are under a much heavier load, and spin way more rpm all the time.

You need to work out a revolutions equivalant. Your truck or car spends most of its time at 1500 - 2500 RPM with a light load. The Boat at 2200-3500 with a heavier engine load.
Change engine oil at 50 Hours on your boat and 3000 miles on your car might be a good conversion of loads because the oil degrades with load and time.

Average speed of most wakeboats is usually under 10mph. A lot of hrs are clicked off in neutral.
If your average speed is say 10mph then 100hrs would be 1000 miles, but you would have to ad for wear and tear an auto doesnt get. Although a boat runs cleaner ie, no dust etc.

I would think that 50=3000 would be pretty close.

Billy,if that is true,then every boat should run at least to 10,000hrs since mostly all cars run good til 100,000 miles.


Needless to say that your conversion is incorrect,tho it sounds good!

Thats why I said ad for wear and tear. If you were to put an odometer on a boat I think thats what you would come up with. Not that it would be accurate compared to an auto. Motors in boats are usually fine its the tranny that craps out. Thats like saying every vehicle should last til 200k miles every vehicle is different ie, Toyota, Honda vs. Ford, Chevy. The first two are in much better mechanical condition at higher mileage.

I don't know about other people but I think the same way about a car with 100,000 miles as I do a boat with 1,000 hours. At that point I would never consider buying a car or boat because after that unless it's been well cared of repairs can get expensive.

Its all different, just like johnsvt Silverado 700hrs to 27500 miles. I'd like to see hrs vs.miles on a Police cruiser. I think its hard to compare. IMHO I would say 750-1000hrs on a boat is like 100k miles on a domestic auto.

billy, comparing boats to cars, so the 'mileage' of the boat doesn't really matter. and 'adjusting' for wear and tear is like throwing darts from 100 yds away.

the 60 factor makes sense b/c of oil consumption. kinda indirectly relates engine wear to each other. 3000 miles: 50 hrs.

so if avg life of a car is 100K, avg boat life is roughly 1700 hrs.

That's adding a lot for wear and tear.

I would say it is closer to 100hrs to 10,000 miles.

nacho I agree, mileage on a boat doesnt matter, it wasnt my question. You tell me what would the mileage be on a boat with 1000hrs that the average speed was 10mph? It would be accurate mileage but not accurate to the way we measure an autos life. 2 different animals, the boat keeps a much higher average rpm than cars so thus wearing out quicker. The question should have been, whats the average life of a boats drivetrain vs. autos? Big Ed so like I said 1000hrs is IMO 100k miles.

This would make a good Wake Poll Question.
50hrs = 3000 miles
100hrs = 10000 miles
etc.
etc.

I have always heard to use 1 hour equals 75 mph. The reason a boat is different than a truck, is a boat runs at constant high rpm, which equals more wear and tear. Where as a truck goes down the road at 2000 rpm's, or less on a diesel, a boats is at 2500-3000 at 25 mph, and higher. Therefore, it is approximatly 1/3 worse to drive at a wakeboard speed than go down the highway (on the engine that is). I don't know if this helps or not.

this is hilarious.

what would also make a GREAT wake poll question is: what is 10000 divided by 100?

Bum bada bum bum WHO CARES!!!! Whats the purpose? Honestly people.

Does that mean you changed your math or opinion??

Big Heavy,I agree, whats the purpose could be a question asked on half of the threads posted.
What about miles vs hrs on the Space Shuttle?

The reason this question always gets asked is because they want to see what kind of shape a boat is in. Most the time when buying or selling. I bought a used boat with 160hr on it so is that like saying 9200 miles? How would you feel buying a boat with 500hrs and financing 20-30k, or more? How many hours are too may when buying???

100,000 miles equates to 1000 hours resale standpoint

I pretty much agree with Mikeski in terms of driveline wear and tear. A driveline should last almost indefinitely in a boat provided it is cared for properly. With a boat you virtually eliminate engine compartment heat which is a major killer of automotive parts (you essentially have an endless radiator flowing through the motor).

The bigger issue to me is how the boat is taken care of and stored. Some peoples 10 hours is like a hundred for someone else. I've got a friend who's parents have 180 hours on their '02 X-star. The boat is absolutely trashed. I sold my '02 Sanger with 450 hours and it looked like new. It really all depends on who owns it.

I guess cars are the same way. Some people take better care than others, but boats seem to go to the extreme. I've seen a lot of low hour boats trashed. IMO, I'd rather buy a newer boat with a ton of hours than an old one with low hours provided the new one looks great.

Anyway, my truck just turned 7500 miles and it's got 130 engine hours on it.

That's 58 MPH average!

Big Ed (Mr perfect)I forgot a zero. I meant 10,000, thats ten thousand. Please don't take me to court for a typo. Oh and tho is spelled though.
Anyway as you say "shut up and ride bitches"

03 gmc 5703 hrs, 165,000miles thats an average of 28mph.

ok,you say it's a typo cool.I was just reading how you posted.....mr.perfect hummmm that does have a nice tone.tho far from it.

Aint we all.
