what kinda fuel will a 1075 suck down WOT?

how many hours is 2 seasons?...........2 mo cents...........

100hrs a season.

Take a ride on a 39Vin a 1-2 chop at 90 and you won't want to go any faster.......................I much prefer the 43V.

Sure the bigger you go the better the ride, but the 43 is going to be 5 or more mph slower on the power in 3 foot and less chop.

You could save 250k and buy my 50 and go 100 in any water. :D

Merc. power is nice but it just seems to me once you go over the 600 hp mark you can do better from the top builders for less cash and make the power on lower oct. gas.

Premier, you seem to be interested in the smaller costs like fuel burn but if you divide the maintenance costs and the higher insurance into the amount of hours that would shock you.

850/1075 rebuilds at 125 hours 52K is $416 an hour if they are standard rebuilds with nothing extra broken. If you pull them at 100 hours your hourly usage costs you $520 an hour. A Top Gun can be insured for 5-6K in S. FL w/ 525's but I would expect 10K+ for a 1075 boat due to 120 MPH capability and added value so that would add another $50 an hour (5K) to your annual boating budget.

If you cruise in the upper 70's mostly with 700's for $570 an hour more you can cruise in the 90's!

A 39 TG 700 boat would be the best bang for the buck in the size/ cost/ HP ratio.

I have talked to JC Perf about these engines. He said that after you take the electronics off the engine it is still a large V-8 chevy. He says with nothing broken and just a rebuild he can do a 1075 for $15,000 per engine

I had that in there and changed it for you!

There really is not that much difference in Maintaince of a Merc. vs any custom motor, if you compare apples to apples. The bottom end should be pretty much bullet proof for 200hrs. The valve train is still just a solid roller set up with the maintaince that goes along with that reguardless of the motor. Thebiggest difference is in the inductions system. The merc has a pretty nice efi system that helps protect itself pretty well. It is also very fuel effecient. The rebuilds could be done by any qualified shop and should cost the same as any comparable motor.

That sums it up Really well!!!! Plus the word "Leakdown". 100hrs A 2006 39 Cigarette in connecticut had 70lbs 2 cylinders, the boat still ran 110 but 70psi is not good. Just a note the new Jesel lifters are expensive compared to standard lifters and require maching the block. Jesel will take your block and machine the block in house. If I had merc motors i would definately take this route. By the way Wayne Jesel's shop is not your corner machine shop.

Merc motors all run pretty fat. More fuel seems to thin the oil off the cylinder walls but cool the "charge". That will produce more ring wear.

Exactly.

Also, doesn't Merc renew the warranty once the total has been done?

Example: You take the 1075/850 to some guy who "says" he can rebuild it for much less than Mercury. You agree and proceed, and the engine fails after say 10-15 hours. Merc will fix it again without cost if they had done the work vs. being up chit creek with the other guy, right?

If you do the Mercury refresh.
Parts are covered for 180 days on the 850 and 90 on the 1075.
Labor comes with a 30 day warranty.

Yes, you get the same warranty as when they are new. And don't forget the 25% discount to orginal purchaser. This will get the price down competive with a sterling rebuild, but with a warranty. Also merc tends to replace alot more parts than most other engine shops.:D

whats the recommended rebuild interval on the 700's anyone know ? i know the 39 cig unlimited with 850 runs in the low to mid 1-teens

i have heard 400hrs for 700s

same as 525 and 600....? so im told.

I know there are quite a few OSO'ers with Merc 700's that have been in and running for at least two seasons. I would like to hear from some of those users as to where they are now on engine hours and what they expect from here on in?
