I have what is probably a stupid question. Why don't you ever see boats for sale with say 1000 hours? If you get your engine rebuilt do hours go back to zero? I just bought a boat with a stock 502 with 440 hours. Is that a lot? If I do a search of lifespans of those engines you get from 1500 to 2000 hours, but I've never seen a boat for sale with those kind of hours. If anyone can enlighten me please do.

those hour's are for cruiser's , fish boat's and run about's . most high performance boat abuse the motor's to much to get those type of hour's . if you baby it then im sure you could get rely high hour's

My little brother put 1200 hrs on a pair of 420 that we built (in one year) and that was with a switch for throtles ,wide open or idel no in between,we call it the Chucky switch lol.

Most go-fast guys run them hard and rebuild them at low intervals so they don't have a catastrophic breakdown.

1200 hours!! That is 50 days of nonstop running, 24 hours a day.

Thats a whole lotta hours.

Yeah that's 23 hours a week for a year. Or 3.28 hours a day, every day for a year. Seems a little unrealistic...

thats also like 60000 miles at 50mph . . . . . . hmm . . . . now i know Chucky personally and know it is certainly feasible if he had an unlimited budget and i do believe he had that summer off, I dont believe his budget could have sustained the $175,000 needed for that trek though (adjusted for 2007 gas prices) lol . . . . . course everytime i here that story it also goes up by like a hundred hours. lol

BUSTED!!!!

OP,

I don't know enough of engines to count, but what I do know, is that Dave's knowledge is something that I won't question.

sold a 29 outlaw with almost 600 on 454 mpi twins. Other owner is still running it fine. If they are tired you would never know it. Boat still ran 69 to 70 all day. He should be around 700 now

Sold my 2000 29 Outlaw with Over 750 hrs 454 mags. NOW it is pushing 900!
Change oil every 30 or less.

Now the Cig w 400hrs and KABOOM!!
F@ck me
