This is the curve from the old engines. Note torque is read from right side, hp from left. Second pic is the final combo going back in. I ended up with the 1 in. spacer. 2 in. made a little more power but peakier/ not as broad.

What would all that TQ be good for in a low RPM motor? acceleration? I don`t use my boat for tubing or drag racing... I want rpm since there`s no gears and the faster the prop spins the faster the boat goes.

Power was way better, and mpg was better, then the engine problems began shortly after.
My 6.7 diesel gets 11.3 mpg at WOT pulling a 43' steel trailer with an almost 35' Fountain on it. Not sure of top speed cause I got cheated on the speedometer only goes up to 100. Truck really doesn't know the boat is behind it unless your running under 40 and lay into it because it starts wheel hopping real bad.

Wait what? You measure mpg at WOT? 11.3mpg @ WOT ?? I get like 4mpg pulling away at the light. so thats pretty impossible.
and who the hell goes over 100mph with a trailer in tow?? You trying to kill yourself or just everyone else on the road??
Jesus man., maybe lay off crack

Sometimes you have to let it stretch its legs a little bit.

I was thinking of putting a supercharger on my 5.3 to help towing. Anyone here have experience with that?

Ha- I was driving home to Chicago 6 years ago from Corpis Christi TX, and some guy flew buy me around Dallas with a Ford F-350 towing a 35-38' Fountain. I thought I would catch up to it and check it out. I was doing 100+ and could barely catch the guy. Maybe it was Black Baja!

Lots of people do that (with their GPS on) so people think they have a 100 mph boat

Just make sure it's not a Livorsi... They don't work and you can't show everyone the tattle tale :-(
