Re: way to tell how many running hrs
This is a bit hard to tell. I know we here in Denmark says a family has an average use of a boat of 50 hrs a year. But if the motor was at a skiing club, its probably 500 hrs a year. If you do a compression test, it will show you the shape of the powerhead. Another thing is, some people can ruin a motor in 7-10 year in bad service, wrong oil mixture ( or in 5 min ) and hard use, some can operate the same motor for 25 years and still in good working condition. Do a compresion test, test the motor on water if possible, and look at lower unit oil. If price is not favorable, demand warranty, or buy new.
