Merc 850's and 1075's-ARE THEY RELIABLE
A buddy of mine is looking at both of these. I couldn't give him any real world info, but told him I would get him some anwsers by posting on here. What is the difference in hours between the 2 before a rebuild is necessary. Is the 1075 as reliable as the 850 with more power or is it not even close from what I have read. Im trying to get him to go with some 700's, 600's or the 525's. He told me the 850's were just as reliable as the other blower motors that Merc builds. What's the concensious. Thanks Jeff

not sure what Mercury wants for rebuild intervals, but on a 600 HP engine you should be able to go 375-450 hours depending how hard you run them. A 700, 350-400 hours. Again these figures are based of what I have seen with engines I have built. Even at these hours the bearings and such looked liked new. I have had 900 SC engines go the same time (roughly 300 hours +) The lower horsepower engine package will have a longer life before rebuilds. Alot has to do with maintaince of course.This is a good ball park.

Thanks for the thread, I was also reading something similiar in this months PB mag. My buddy trying to tell me that 300-400 hours is not uncommon without a rebuild on the 850's. Jeff
