How many hours are on your engines/drives?

[Knot Waiting]

Although I'm pretty sure this is one of those topics that has been brought up again and again; I cant recall seeing it and I'm curious about longevity. So here's the latest version:


- 730 hours since 1991, so 22 years. I bought it with 704 last summer. Mercruiser 7.4 Mag / Bravo 1

Re: How many hours are on your engines/drives?

I think everyone needs to also say what time span the hours cover, to have any meaning.

I have put 380 hours on my 2003 Yamaha 150 since I bought it 3 years ago; don't know what it had before. That's not much for around here, but the children aren't using it much lately. Also seems like last year the weather was bad on weekends and striper season ws a bust, so lots of short runs but few long ones. But the season has started! Will go for 500 by labor day to make up for it.

25 years. No idea how many hours.

1997 Evinrude outboard = 2100+ hours first go around. New power head in 2012 = 32 hours

Without getting into the big discussion again....

Based on the amount of Work performed, and comparing similar sized engines, both properly maintained;
1 hour of boat engine time roughly compares to 100 road miles.

The engine on a boat with 1000 hours will have similar wear as a road vehicle of the same size with 100,000 miles.
Your mileage will vary.

2004 Lugger L1066 (173 HP) = 3256 hours and 17786 nautical miles traveled since 2004.
On a diesel engine rated for continuous duty, that's just getting broken in nicely!

18 hours

Re: How many hours are on your engines/drives?

1220 on the engine and at least 500 on the drive, one rebuild on the outdrive and change the fluids every year. 1989 SeaRay 220DA, I've put 500+ hours on it since I bought it 5 years ago

I have heard that an improper prop (pun intended) can really torque your engine life. If you run 1000 RPM's over the engine's recommended top end, you add 1 hour of wear for every minute you run it. I learned this when we wore out a brand new Yamaha 50 on a hunt club boat in about 2 years; the mechanics said it looked like a commercial use motor (crabbers, etc.). I'm sure the stats are just anecdotal and don't intend to provoke the engineers to empty their pocket protectors, but it makes sense in general. I'm sure than "lugging" has an aging effect, too.

Just turned 119 hours. Bought it new in August 2011.

That 1 boat hour to 100 road miles number wore out a few pocket protectors and a slide rule in the making.

2009 Rinker, had 112 hours on it when I bought it about a year ago. Now has 154 hours after one full season with me.

That should go 20,000 hours easily. Ever follow the Wind Horse blog? I'd love to do that kind of exploration. See: SetSail ? Wind Horse

Boat is 41, about 700 hours, OMC Electric Shift Stringer. I've probably only been able to put about 30 hours per year on it since I bought it in 2010.
