Just got back from Lake Erie this evening so and I took notice on what the old girl did

81 23' SF CC
Twin 81 225 black max's and a 95 9.9 merc
19P stainless merc stiletto's
Lenco 12x12 tabs (great)
20 knots is about minimum plane speed 2800 rpm's
3800 rpm's best cruise 28 knots near as I can tell 1.5 mpg
6000 rpm's wot (only have the stones to do it for a few seconds to date) hit 57 knots gps and until I get the floscans next spring I have no idea the gallons per minute.
Hole shot...good thing the leaning psot is secured well.
Typical load is about anything I want to haul on her, she'll haul 5 guys and gear just as easily as when I'm by myself. Only the 2nd season with her and the boat amazes me.
