4400 rpm & 37 mph sounds about right based on variable loads to include amount of fuel. I'm still figuring mine out. I was getting 4600-4800 WOT and 40-45 mph with a 14 x 23 aluminum prop with just 2 adults and about a 1/4 tank of gas when I first had it in the water. I ended up having to replace the prop after I introduced it to a sandbar in Great Bay. I put on a 14 1/4 x 21 stainless steel prop and now get 4200-4400 and 38-41 mph with 2 adults and about 3/4 tank of gas. I think I'm good with that and attribute some of the loss to barnacles, bottom paint chipping and whatnot from having it slipped in brack water for almost 3 months. Good luck and have fun out there.
Great Bay?? I grew up in Mystic! Small world.
