Murray,
Indeed ... by the 20hp per gal rule that would be 18gph WOT. Beast yes.
There’s a Willard 30 running around w an 80hp Cummins 4cyl.
A lotta guys sure like their beasts.
Thank you S of F, Soo many the same color.
Dan, sorry I misread that. Even I have 100gal of water.
"20hp per gal rule" - for diesel only I guess??
BTW... Our Tolly carries 77 gal fresh water. Never have problem as we use water at "Boat Speed"; in other words... very low flow! And, we drink out of 1 gallon, clear material, carry on water containers.
