Really interested in the Merc 1100's ,but can't seem to find how many hours are expected before breaking them open.
I have read where they have the longevity of 525's,but what will they need? 525's=top ends and headers.But what will the 1100's need? Complete refresh? And who can do them besides Merc,at probably 50K each?
Thanks Jeff

Ok How about 1350's then?

Maybe just a rumor, but I heard complete rebuild at 50 hrs on the 1350's!

I researched this as well and…….not many. I was quoted 200 ish hours then they go back to Mercury for rebuild. Essentially, they only use the core and give you an almost completely new motor with warranty for more like $80k each. Again, this is what I was told from a well respected shop and not Mercury.

I stopped at that point because even $50k each is too much for me when I can get my Sterlings done for about $25k for the pair.

Not true.

The 1350's were designed to last significantly more hours than the 1075's. Most 1075's will need top ends around 50-75hrs and full rebuilds in the 100-150hr range.
I believe that the 1350's were expected to go twice that.

That's what I thought as well. No one has responded with any major problems,so I guess no news is good news. I may try the Mercury blog,and see what the expected hours and cost for rebuilds would be.
Boats like Windship have been around for a few years,and run alot of Poker Runs,any one know how many hours on his 1350's?

PM John. If I remember I think he just had them rebuilt. I'm sure he would be happy to give you some info.

i would call tommy at chief, and see what kind of hours he is putting on his turbo motors before going through them...

We just trade in our cheif 1350's at 257 hours and they checked out perfect
we just couldn't pass up the newest version which produce about 1600 on racing fuel and will run about 1100 on 89 octane
so i have heard from very a reliable person that i know who owns three 1350's you will be lucky to make it to 40 hours
now remember we do run them very hard
when you compare to two different builder the cheif have alot less moving part.
