High or Low hours on a 4 stroke.

[pborden]

What would be considered high hours on a 4 stroke motor. Looking at a 2003 70 4 stroke suzuki for a repower of a Boston whaler. Is wear and tear diffrent on a 4 stroke vs a 2 stroke. The motor has 850 hours on it. Worth the money or truoble waiting to happen.<br />Thank you

Re: High or Low hours on a 4 stroke.

With normal care and maintenance that engine should be good for 3,000-5,000 hours, Westy.<br /><br />One caution. On routine maintenance DO NOT let anyone adjust cam drive belt tension by any method other than described in the Service Manual.<br /><br />The only real problems I have heard about were a few engines in which the belt was overtightened and broke the nose off the cam.<br /><br />Worth the bux? How many bux? Year old and 2 year old DF70s coming off lease with about 1500 hours have been bringing between $2500 and $3500.<br /><br />It's a truly great engine and loves being on a Boston Whaler 17. I have one on my Montauk and it is the best outboard I ever owned. That is a lot of outboards.<br /><br />Good luck.
