That Pursuit is way underpowered w/ a single 250, no wonder he only gets 1.85 mpg. I love my new outboards and would not go back to an I/O, IMO outboards are designed to be in a salt/corrosive enviroment and they are designed to run at high RPM, cant necessarily say the same for I/O's. My last boat was a PQ 280 with a 502 MPI, similar size and weight to my 30 Concept w/ 225 Optis, I havent run any figures yet but I know I get better MPG with the new boat, especially idling around.

I can tell you first hand that my new merc 300XS get double the fuel mileage of my big blocks. The new optimax motors are incredible.

In the same boat???

Yes, the same boat.

we have a 33FT concept with 300 e-tec's and getting about 1.6 mpg when it had 250 efi's got about .9 mpg

250EFI's are gas hogs, but that is extreme, I get about 1.3 with my single 250 on a 24 pantera

Funny how there's never any real comparison numbers... inboards to outboards. But, is it not true that four stoke outboards came about trying to give us the efficiency of an inboard motor in an outboard package?? That boats need torque, and displacement provides it? On a light boat, yes, but when you put the throttles down and tax a small displacement outboard to push a heavy boat, it sucks down fuel. 29’ Regulator with twin 250 four strokes 1.1 mpg. 28’ Pantera twin 6.2’s 2mpg....

Outboards are easy to work on, less maintenance, cleaner, but in the situation they’re being used in a lot these days they’re not more efficient.
