| What would be considered high hours on a boat motor? 2 stroke vs. 4 stroke when would you need either rebuilt or do you just wait till it breaks? |

Location: Princeton Mn. | I can't answer that one, it really depends on the use. Myself I have a 1998 Mariner Optimax with around 600 hours. May seem like alot of hours but they are "gentle" hours.  Over 500 of them are under 1000 rpm, you see I troll alot. Now if you find a tournament boat either bass or walleye their big motor will have very few hours, but they will be "balls to the walls" hours mostly.
Their are alot of things to factor into todays motors but for my money if they are ran right, maintained, and get regular maintainence they should last a good long time.
If you are spending major bucks on a used motor have the computor read and see how it was ran, money well spent! |

Location: north central wisconsin | We really do not know, honestly. As far as alot of outboard experts are concerned, we cannot put enough hours on a good one to break it. Lots of people running the snot out of some pretty old outboards yet. I run a 1984 Yamaha 40 that I'd hate to guess the hours. Still runs so I don't ask... |

Location: Eau Claire, WI | I wanted to revive this one to see if anyone else had thoughts on the subject. I'm not sure when to be concerned about hours on a motor. I have no idea how many mine has but it's an old 50 that's been around the block but still runs well. As I poke around for a new boat, I'd like to be informed as to what the number means. I understand that 50,000 hours by grandpa is probably not as bad as the same time in by fast eddy but is there a line that you guys won't consider crossing when you don't really know the history of the boat/motor?

Location: Mauston, Wisconsin | Well- that really depends on the depth of your wallet! For me. I'm running a 88' 150HP Johnson on my 85 Skeeter. Yup, I have had issues, including a lightning storm taking out the entire electrical system, incuding the control module and the voltage regulator (this was while parked on concrete driveway in front of my house.). ~ $800 later I was back on the water. I have no clue as to the hours on this motor. All I can say is, it will run like "raped ape" or troll at 3-10 mph all day. Yeah the gas mileage sucks! But so would buying a new 150 HP. I can buy a lot of gas for the cost of a new motor.
Watch your fuel quality, do regular maintenance services and most importantly have it tuned by someone you can trust!
Have fun!

Location: Wishin I Was Fishin' | Make sure you run at least 16oz. of Seafoam mixed with 3-5 gallons of gas at least once a year to get the carbon out, especially if you do a lot of slow speed running. Carbon can build up under the rings and cause a failure. It just makes em' run better too.
OEM factory 2 cycle oil is also very important in my book too. Not worth it. My last engine I ran cheep fleet farm oil and when I tore the block down I had a tremendous amount of wear on the block from the crank rings. No fixin' that either. |
