hey seasick been awhile .. glad to hear from you , I asked the question because my 2000 Yamaha 200 hp is going on 1200 hrs. I always maintained her, however every year that goes by im putting more and more money into her. example.. last year fuel pump, 3 sensors, year before that oil pump, and electrical parts etc etc etc .. when is enough, enoughI agree that hours by themselves don't mean much. A new motor can be poorly maintained and/or abused.
In fact, a 10 year old motor with 500 hours would probably be a better bet than a 10 year old motor that was never used since the later probably sat without any maintenance.
I am aware of outboards in commercial applications running 6000 hours or more. In most if not all of those cases scheduled routine maintenance periods were strictly adhered to.
At the same time I have seen relatively new motors beaten to death. I call many of those operators the "Two position Throttle" crew. For them it's idle or WOT!
If buying a boat with a motor, I always tell folks to look at how well the boat has been maintained and if it shows care by the owner, there is a better chance that the motor(s) were properly maintained also.
A ship/service log is helpful also and just by itself shows care on the owner's part.
That said, if a boat looks really clean, too clean perhaps, it was probably detailed prior to sale and for me that can be a red flag in some cases.
A compression test cab provide some assurance especially if you or the mechanic inspects the plugs for signs of problems.
One more thing: Standalone hour meters are not to be trusted. If the seller states the engine hours, unless they can show some sort of proof, that data can't be trusted either.
Jargon is also correct stating the typical annual hours for most pleasure boaters. I believe the stat is that 90% of pleasure boats run less that 100 hours a year.
My yami on my 208 is 20 years old. I really haven't gotten to the point where things are falling apart but it is obvious that some things have more 'wear' than one might like. Recently, I have been working to find and hopefully fix a leak in my tilt pump system. I had resealed all three cylinders and the pump housing two seasons ago but this time I am unsure where the fluid is coming from. I did make one change but I can't say for sure if that will make a difference. I will let you know.
Of course, I thought about a replacement tilt/trim system but new ones run about $2k and its just not worth putting that kind of money into that motor. Used is an option but I might just end up with someone else's problem. At some point it will be time to make a big decision; Repower or move on to a newer boat. The recent stock market 'crash' may put the kibosh on that plan. ( I have to look up what the derivation of 'kibosh' is).
Well, just rambling on. Getting quite bored 'sheltering' here in NYC.
Thank you for the explanation, I only do fresh water, and 3 months out of the year it is solid.in this context...a boat with bottom paint has been kept in the water for season after season..in the case of Florida, all year/ year over year.
That would tend to lead to more corrosion.
