While on the no load thread this came up (see my own quote below) and we've talked a lot about how long a diesel engine can be expected to last and all know that the gasoline engine is considerably less long lived. But of how much importance is that? How many of us have had to rebuild gas engines in their previous boats? Not many I suspect. I think the long lasting reputation of diesels in pleasure boats is over played and most of us would be just as well off w gas engines IN THIS REGARD.
The actual life expectancy of gas engines is probably best represented in automotive histories but that's a different application than boats. But since there's so few starts in the total hours perhaps boat engines could last longer BUT boat engines work much harder ................................................?
Awww Al give him a break,
That means if I had a gas engine it'd be 2/3rds worn out .............NO WAY!
Diesel is nice'n safe and twice as economical (fuel only) BUT THAT's it.
Gas engines are MUCH smoother and quieter and last a long time. My 73 Buick has never had any serious maintenance .... Heads never been off and it's really strong. Could use a carb rebuild but it runs perfect all the time. If it sits for a week or so it looses it's prime but that all. It's seen new shocks, batteries, the usual break work ect but to say the car has lasted and gone the distance ( over 100K) is an understatement. 100K is not high millage now but in it's time it was. Did some numbers and you are closer than I thought. 100000 miles at 50 mph is 2000 hrs. Not all that much actually. I've gone half that w my Mitsu and consider it basically a new engine. I wonder what they're say'in a new 350 Crusader w fuel injection would do re life expectancy re hours? So it looks like a modern gas engine should go 5000hrs and. A diesel 10 to 15K. I'll start a new thread unless someone beats me to it ....... I'm at Barns & Noble on the I-pad.
