Or is that just a recommendation?
Showing my age here but the water gets awful hard above 35mph. Kinda hard on joints and bones.
Some states and the USCG do enforce the labels.
About 33 with a couple of people and full tanks. Engine is old. 73, and I was told 115 isn't measured at the prop back then. No power trim, just power tilt. Have to do it manually. Did it all the way with the 5 holes, and couldn't turn without cavitating, so went back one hole, and I guess that's all I can tweak this one. Just ordered a 13 1/4 19 pitch to replace the lightly damaged 13 1/4 17 pitch currently on it that gets 5300 rpm. Manual says 4,500 to 5,500 with the full 115 at 5,000, so I thought I'd drop a few hundred rpm, and see it the new prop and pitch will get me close to 40. I know my old glastron with a 135 did 45 easy. Little heavier boat as well, thus rated for 140 hp, I guess is how they rate them.I would think the boat in your sig should run 40 MPH or so with it's rated max hp running correctly and with the boat in good condition and correctly propped. Mercury 1150 TOP should get there if everythings in check, but even a 'rude 115 should have the ability.

I'm gonna run to autozone, and check out how much for a compression tester, and check it, grab 4 new sparkies, and some sea foam. As for the rpm, the manual says it produces it's 115 at 5,000 rpm, not 5,300 where I'm at now, so I thought moving up a prop pitch to the 19 from the 17 "slightly damaged one", would get me to the magic 5,000 number.
