Why so many new powerheads? #12381912

I bought my boat in 1997, brand new from Fun n Sun and have never had to replace the power head. My engine doesn't have an hour meter on it, but I can imagine there are well over 1000 hours on it. Why am I seeing so many three and four year old boats with new power heads and fairly small number of hours on them? FYI, I've always run mid grade gas and good Mercury oil. But I use ethanol gas( or non when I can find it, but rarelyl), don't have a water separator in the fuel line that I'm aware of, and have NEVER used a fuel additive. Someone have a good explanation? Thinking about buying a new (er) boat because of all the new goodies on them, but man...that's a little scary. Especially with the prices of newer boats.

Yamaha did a voluntary replacement on their SHO's a few years back. I just wonder if the newer ones are still having issues?

And Mercury has compressor issues... seems to be such a gamble on the brand.

Seems like they will all blow up , bad fuel is some of the issue , lots of guys let their boats set for months at a time . Just my opinion , as a ASE master auto technician . Lots of guys run their boats wide open for miles , and just burn them up . Run any high horsepower engine at red line for long periods of time , and they break . For the money the manufacturers are charging for power heads , they should be ashamed ... But the problem may lie , in the nut behind the wheel !

More parts controlling fuel/oil/air mixture on the new DFI motors vs. carburetor motors.

A lack of maintenance and/or low usage adds up to a disaster with outboard motors.

I would rather buy a boat with 300 hours on the outboard (that has been maintained properly) that is 2 years old than one that has 50 hours and is 5 years old and was used sporadically.


We didn't catch 60+,might have boatd in the 30
should,we didn't have fun expept alot more thie time of yearhope you get ready you'll be calling mr or E-MILK to a foods donatiom,,,Arter drin some red bullmdnd Vodlea

Why would low usage be an issue if maintenance was done correctly?

Low usage has noting to do with it. Usually its from stale fuel that's been sitting a long time is why people equate it to low usage. If fuel stabilizer made for fuel with ethanol us used regularly then its a non issue.

I believe that 150 and under are tanks. They will last a long time with proper maintenance. 200 and up do everything right and they still pop. Just they price you pay for speed.

They don't make money on powerheads that don't blow up,

ever watched boats at the lake? People drive the hell out of them and bass boats are the worse. People run them trimmed too high and hit a wave and the prop breaks loose and many times there goes the motor.

That can be avoidable to a degree if the captain knows how to drive.

lack of maintenance letting them sit too long between running an poor operating choices like in the winter backing it off the trailer an hammering it an some are just mechanical failures .

Too much red line will kill any motor, when it was time for a new motor I found a 1979 Johnson 150 , now before you say 1979 !!! , I like the older models, they are easier to work on , parts are cheaper and I think they where built better, just think about it back then companies didn't cut corners to make a profit like they do today. I checked out everything before the cash traded hands and after a little TLC she is running like a top, now with all that being said I think it is 90% how you take care of something and 10% luck 2cents


If it was easy, everyone would do it
