Default How many hours is too many for an outboard?

Please spare me with the "if its taken care of it doesn't matter", it does matter, and I plan on making sure it was taken care of property but 100hr service doesn't make a motor run forever, hours still matter for the dozens of other outboard parts

The second it blows up is to many hours.

Depends

There are some rich guys that think 200 hours is too many

I have 1500+ on my OX66 and it still runs like new

The Catalina Island harbor patrol puts 5000+ on Honda 150s without any major problems

There is no single catch-all hard number. There are far too many variables to know how a used motor will hold up. The way I care for a motor will be different than someone else; both of us are doing our dead-level best but things get missed and/or mis-understood. Buying used is a crap-shoot and existing manufacturer warranties are just about the only way to make them equal.

From personal observation of friends of when they repower:

Commercial application: 4000-5000

Recreational application: 2000

This doesn't mean the motors are no good or no life left, but at near end of useful predictable life. The difference between the two is commercial runs more during the year and thats good. Recreational may get 300 hours a year from a "hard core" guy which is still sitting alot.

I'm not sure you can ever put "too many" on an OX66.

On my EFI's, 746 was fine, but 746.2 was too many.

If I'm buying used, anything with over about 750 would have to be priced as a repower.

this has been asked 1000000 times

lower hours are typically worse than higher hours. i would not touch a motor with less than 25-50 hours per year and my upper threshold would probably be 150-200 hours per year

Wow, start off a post with, "please spare me with the bla bla bla". I'm surprised anyone even replied with a decent answer.

Well you sir would be pissing away a ton of money. Im at 2300 hrs run like a top bought with 1600 on them . I certainly think about when it mite be time to repower but I trust mine just fine. When the time comes I will likely look for a used set from somebody like you and enjoy them for 8or 10 more years. If you have the dough hang new ones every year but thinking 750 is time for a repower is just silly.

I mean, someone has to say something on this forum. Its literally 75% full of people telling other people why the question they asked isn't something that can be answered. People have 50000 posts which none are actually helpful just arguing nonsense

I didn't say I would repower at 750 hours (or didn't mean to anyway). What I meant to say (if I didn't) was that if I was buying a used boat that had more than 750 hours on it, I would try to purchase that boat at a price that took the need for future repower into consideration. I understood the OP's question to be "...how many hours is too many on a used engine that you don't know?" I fully intended to run those EFI's to north of 2000, but the rod came through the side of the block and changed my plans. I've been way way out on old OX66's with well over 2,000 hours that I trusted completely. Sorry for the confusion.

Default She's dead Jim..

I sold a Rude Classic with 7492 hours back in 2004. The 7492 was according to the servicing dealer. That was out of service record, Tiny Tach, hour meter and according to servicing dealer the ECM. The boat with it is still running around the FL keys digging new canals...

I didn't intend to bash in any way but I suppose my thought process is that the 2k hr mark is time to start thinking about a repower. Obviously that would be on motors that I thought or knew were well cared for. If I had thrown a rod at 750 I would imagine I would be a little nervous on any motor at 751. Mine are Yamaha 3.3 four strokes and I would likely go back with yam unless I found a deal on another brand. Im really not scared of any of them anymore. Hell I have a ficht on a litte work boat but its on a lake and never far from land.

Lots and lots of different variables to take into consideration. The make and model of the engine, how it was cared for, how hard it was ran etc. Maybe shed some light on why youre asking and we can point you in the right direction.

Generally in a used motor you want to see it ran. Typically around 50-100 hours per year. But thats not always the case, I have a 2002 Merc 225 EFI with 550 hours on it, 200 of which ive put on in the last 2 years. The boat was repoed and stored without use for many years, then resold and lightly used by a few owners. I had about $5-600 in maintenance to do when I got it but now the motor runs like an absolute champ and I trust it completely. Those motors are known to run strong for a long time. The yamaha ox66 is another beast that will run well into the 2000 hour range. The yamaha F350 probably not so much. People say the 4 strokes dont run as long as the older 2 strokes but Ive seen plenty of 4 strokes into the 3000 hour range on commercial boats. Like I said, many variables.

The reasons I plan on repowering are the boat really needs a 300 for its size and Merc EFI's arent very fuel efficient, plus the technology is out of date. I plan on looking for a used suzuki 300, with fly by wire controls and would prefer one with under 500 hours of use. If that motor performed well Id run it well into 2000 hours.

There is no absolute bottom line answer to this question.

For me it will be whenever the engine doesn't work as well as I want it to. Have no idea when that will happen, but I fully expect that the current engine will outlast my ownership of the boat. It's already got 400 hours on it.

If I was buying a boat, IMO if the engines run fine and are in good condition, the number of hours on them doesn't mean a whole lot.

I wish hour meters included gallon meters also. People love to claim how some crabber or slow speed troller got 9000 hours on XYZ brand. Gee, I wonder why. My engine usage breakdown seems like I abuse my engine. Most of my hours are between 4-4500 rpm. My trolling is by electric trolling motor. My outboard is for carrying the hull to the fish, then shut if off. I roll my eyes when people mention crabbers. Those guys idle around from one trap/pot to the next.

I subscribe to how many years you can expect hoses and other parts to become brittle, and how many gallons you run through the engine.
