almost 10 mpg at 30 mph, but who wants to go 30?

I finally got my Merc Monitor working this year and I can now get a mpg reading. SS2000 with a 200XS ROS gen 2.

Nothing unexpected so far. I have a few more props to try and I want to try some props with people on board. Running just a bit of throttle but not planing tanks the fuel economy. I suppose I should idle through no wake zones.

24 Drag 4

8 mpg at idle, 3.3 mph
8.6 at 30
7.8 at 40
7.2 at 50

28 Hill Eagle 3 Blade (ET similar)

9.8 mpg at idle (3.9 mph)
9.7 at 30
8.5 at 40
7.8 at 50
6.7 at 60

That's crazy good economy. On my V-King with the 250 opti and a 29p tempest, I get a best of 8 at 40 mph or so. My reg opti 225 got right at 8.5. Using the same prop.

That 28 looks good, probably the best all round wheel.

Love the Optimax fuel economy. I think the 200xs is one of Mercs better motors.

I remember a BRP boat test with a 200 on a light welded alum bass boat. It got the same mpg at wot that it did at normal cruise. That was the craziest thing I have ever seen. But the best mpg was around 6 if I recall correctly. So still less than the 2.5 opti. This may be the most MPG I have ever heard of from a boat.

That is some cheap boating!
24 Tuff 300xs with a 32P Bravo and 2 people half tank or so.

2500rpm 35mph 6.6
4000rpm 62mph 4.9
6000rpm 95mph 3.8
