Suzuki 2 stroke gas usage

Megabites · 06-27-2008, 08:56 PM

OK all you 2 stroke experts out there. My boat has 96 twin 150 Suzuki EFI engines. One is counter rotating. My starboard engine burns no less than 2 GPH more then the other engine at crusing RPM. Adjusting trim has no effect or makes it worse. Also at any other speed it always uses more fuel. To even them out you have to drop around a thousand RPM which obviously is not an option. There is little to adjust on these motor being EFI. So what is the most likly reason for the difference?

Have you had this boat a long time and some history, or is this something we have to figure out on a new to you boat?
Could be something simple like one engine has an incorrect pitch or cupped prop to the other one.

THis is a new to me boat. I am ordering new props to eliminate the possibility and to change the power range slightly. I am hoping that this will fix the fuel usage issue. I'll post after I get them installed and tested.

Do they each have separate tachs?

Yes - Each motor has a full compliment of guages all its own.
