Life expectancy of a Yamaha F225

I think if properly maintained with records I would not worry about it. However, with that I also would say I would not pay a premium for the boat because of the motor as well. 1993 23' Walkaround Whaler Drive

If this 2003 Yamaha 225F has 900 hours on and the constant speed of the motor was 40 MPH(which would never be the case) that would be 36,000 miles, not much by the standards of a 2003 Car and/or Truck engine. especially if it's well cared for. I've never heard this discussed or have I asked this question before. Anyone have a specific answer to this question. By the Way, in August 2006 I bought a 1985 Revenge 22 WT with a 1985 Yamaha 225 on it, It runs like crazy, I had it checked out when I first bought it and have had it professionally maintained since, next time I take it in I'm going to check with the Yamaha dealer and ask if there is a way to determine the number of hours on it, I seem to remember the previous owner saying he had it plugged into a computer diagnostic system at some point during the time he owned it. Last year I ran it out 56 Miles to Isle Royal in Lake Superior for a week without a hitch, and right now I planning for an 8 day run to the North channel of Lake Huron last week of July/first week of August. All this being said 900 hours just doesn't seem like that much to me..... Pat

Automotive engines do not have this acid running through them all the time. While modern outboards certainly have come a long way in fighting the effects of salt they are still not immune to them. Also, all of the electronics are effected by it as well. The freshwater is a god send for our boats as well as the motors and the reason your 1985 is still running strong as well as my 1974 Evinrude! Both of which are still on their original powerheads. 1993 23' Walkaround Whaler Drive

If the car is run at the same rpm as the boat then I would think you would need to at least double that distance. Guessing at around 4,500 rpm for the boat to travel at 40 mph, the car would be really flying and covering much more ground. Mike
