Jeff...I heard that the 1075 was a 75 hour rebuild. If you go thru Mercury Racing it will cost you about 25K a piece for them to go thru it. I don’t know what the local engine shope is charging for the rebuild. The 850 is a little longer, I am thinking 100 to 150 hours. Go with the 700 package... One year warranty and 700HP at the prop!

My buddies 42 gtx has 1075's one lasted only 25hours before it puked, Merc told him it would take 6-8 weeks to rebuild it and they where :D subbing it out to Sterling. He didn't want his season to be over so he purchased a spare!

These are the stories I have heard, not been very favorable. To be fair though, these were on all very , very, Hi-Perf. boats where they were entered in poker runs. We all know what the majority do on these runs, no different then my buddy would do. Jeff

A Complete rebuild on Merc 1075's is about $12,000.00- $13,000.00 each on average that I have done.

That's what Im trying to get him to do. But at 700hp it will take 3 to do the same as 2-850's to achieve simuliar mph. Actually 3-600's would almost be the same mph as the 2 850's, but he swore not to have another bravo boat. Hell, I personally would be happy with 2 stag. 700's, less maitenance, safer speeds for me, less ins. and so on. But that's just me, I'm the guy usually last getting to the card stops, :D Jeff

That's very fair:cool: , what about the 850's. Thanks Jeff

maybe it's just me but that is an insane amount to have to send every 75-100 hours or at least once a season depending on where you boat. I would rather spend the money with JC, dean or Mark or someone and not have the Merc name and get 200 hours out of them.
