Is that a lot? Or only just run in?
The engine is a 1992 Mercury 75, on a Fletcher 14ft; first used in 1994. Main use is waterskiing, so stop/start & hard acceleration. I've had the engine from new and looked after it.
I'm quite happy with high mileage cars but I've no idea what kind of life you'd expect from an outboard. A quick calculation shows 250hrs on a car would probably be around 7500 miles i.e. nothing.
What hours are your engines showing?
Mines done 150 hours now (four Stroke 100HP YAMAHA), i have done 50 hours this year. The manual relates about 200 hours to a years service. And that the timming belt should be replaced every 1000 hours or 5 years. Not sure if this is a direct comparision but cars normally have their belts done at 60,000 miles and a car has had a good innings at 100,000 miles so maybe 1,400 hours is a good innings for an outboard? God knows!!!! Anyone else?
When looking at boats i was trying to work out how many hours an inboard is good for but never found the answer, I came accross a Mercury 2 stroke 135 that had done 62 hours but it was completely screwed and had alreday had one head replaced by the looks of it.
