18SF planing speed and performance questions

[Snookerd]

I think you're under propped. I had 2 18 SF's with v4 130's. One had a 17p and one had a 19. They both planed and cruised at lower rpm. What is the level of the water line at the stern? Water logged foam in the stringers?

Its still the factory water line (hasn't been raised any over the years, verified when I sanded the transom down), with the boat just floating, loaded for beach, there's about an inch or two of bottom paint showing above the surface of the water.

I also removed the aft fish box for bilge access while doing the transom job, and the stringers appeared sound at that time.

Also, fuel economy seems OK, I guess? Dunno really.
Burned about 18 gallons going from Sesuit harbor in Dennis to Barnstable Harbor, tootling up the harbor and then back to Sesuit.
Last weekend going to Wellfleet and back (from Sesuit) burned maybe 8? 10?
Kinda vague I know... Not sure of the mileages either...

Sounds like the prop
