Acceleration and efficiency
#21
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.

Yep, I made the mistake of buying a brand new F350 Lariat with a 5.4 Gas engine. Felt fine around town. Hooked the boat to it, towed to loto, omg, what a dog. Dam thing spent most of the trip revving its azz off and got horrid mpg. Quickly traded that in for the 6.0L diesel. Power was way better, and mpg was better, then the engine problems began shortly after.

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

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.

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!
