I just got around to reading my Februrary Mercury Product Newsletter and it has the specs and performance curves for the 2002 200HP EFI 3.0L 6-cylinder SeaPro/Marathon outboard. It's for export only.
When I read the numbers I about fell outa my chair. Get this;
Peak torque @ 3525RPM, 495 ft-lbs.
Rated engine speed 4500-5500. On the accompaning performance curves chart the RPM scale stops at 4029 and shows over 210HP.
I'm not real familiar with this engine but seems similiar to the US version but appears to be a real animal. Maybe that's why lhg like his so well.

Wouldn't 495ft-lbs@3525 be 332HP?
Maybe 495ft-lbs is a misprint?

Data's both on the spec sheet and the performance curves.

I can tell you this: if you are on WHALE LURE (with twin 200-EFIs), running along about 3300 RPM, and you shove the throttles forward, anyone not hanging on will be thrown over the transom.

495ft-lbs @ 3525 rpm is 332 hp. which obviously is impossible if the motor is producing 210 hp. @ 4029 rpm.

Perhaps the units of measurement are not foot/pounds?

Don't get too excited guys. Standard procedure with "Commercial" outboards, is to use lower HP ratings than the block would normally produce, which is what they are doing. All recreational Mercury 200's are built on the 2.5 liter block, as are mine.

The 3.0 liter block, which IS a real powerhouse, is used for the 225/250/300HP engines, both EFI and Opti's. So detuning one of these to 200HP would produce a real high torque sleeper. I've been saying for a long time the Merc 225 EFI is the strongest 225 out there. This is why, and why they literally control the twin outboard go-fast market, in all 3 HP ranges.

Why I repowered Whaler Lure, I found out I could buy a set of carbed 225's for the same price as the 200 EFI's, literally. But in looking at the prop charts, top speed was showing an incredible 72 MPH. So I stayed with the 60 mph 200's!
