Everyone one has said the 600's are only good for 2-3 mph top end on most boats over the 525's.

So then that begs the question- why? What was/is the thinking behind the 600's as a power-plant? Surely not for the extra 2-3 MPH- what am I missing?

Detuned version of the 750hp package Mercury will be coming out with including a new drive between the bravo and #6

It's actually going to be a 725.

Mercury will be finishing up the testing for this motor in the next 30 days hopefully they will have it finalized for Miami. The HP for the engine can be either crankshaft or prop shaft, like the HP500 was 470 propshaft HP

They still need to put a bigger gas tank in the damn thing, no matter what engines you put in it.

AMEN!- 4 hours and your empty!

Lots of conflicting info on the new Merc 700/725 package. Some say it doesn't exist. just a rumor. Some say Merc is holding their cards till Miami. I actually have no idea but a customer is ordering a new 382/600's and heard the rumor,he wants the new package if it exists. In all fairness,what does Merc want me to do? I will hold the order till I get the real story, but it seems unfair to Formula to have to wait.But we will wait, my customer's desire comes first.

Mercury did this to all the boat manufacturers a few years ago with the introduction of the 525 as well. Gave them no warning, then instantly obsoleted everyone's inventory of 500EFI boats.

I'd still go with the Volvo 350/DP diesel package. Cruising speed is just as fast, and you get 1.5 mpg in the process. And a drive that won't break.
