'89 Evinrude V4 90hp

Could anyone give me a rough idea on what kind of fuel economy i should get from my outboard? I'm running 2 20ltr (about 5 gall i think) tanks, but even at half speed i'm only getting about 30-45min out of a tank.
Cheers.

You will use approximately 9 gallons per hour at WOT. Significantly less at lower RPM. Rough guide is 10% of your HP in GPH at WOT.

Thanks Kenmyfam,

Looks like a service is in order and that is some really handy info to have learned.
