Re: GPH numbers on 18' w/ 115
I have been registerd for a while but do not post much. I have a 78 18ft seacraft and mine too has a 48 gallon tank. But I have a v6 150 rude on it. To my best calculations I get about 2.2 miles to a gallon usually running at 4000 rpm. I want to install the NAV MAN but have not found a good place for it. May I ask where you installed your NAV MAN? Thanks.
