Boat - 86 Mantra 16' Tunnel (305lbs hull) very similar to CP Tunnel and Texas Tunnel bottoms
Engine - 440" BBC (nothing too special, guessing 550hp ish)
Pump - 1994 American Turbine with a B impeller
No droop. No diverter. Center blocker loader. No inducer. 3.125 nozzle. Currently has a 5 degree wedge.
The boat runs really wet it seems. Before the 5 degree wedge, it was running in the water up to about the drivers seat. Now it runs in the water at about the back seat. It runs pretty strong up to 4200ish rpm's and hits kind of a flat spot for a second, and then pulls to 5400rpms and that's all she will do. I'm not sure what mph 5400 is with a B impeller, but I feel like it should turn a little more than that as small as the boat is. Am I wrong thinking that?
How do I measure for all of the items in the pump setup? It's a radius keel, not a flat keel. Do I measure off the bottom of the radius? The side where it's flat? Where do I go from here?
How far should the loader hang down?
Should I put in an open loader?
How far should the shoe hang down?
No droop/Full droop/Mini droop?
Ride plate angle?
Wedge or no wedge?
On this short of a boat, how dry or wet is it ideal to run?
It did pick up quite a bit when we went from no wedge with the pump aiming 4 degrees down, to adding a 5 degree wedge in it....I'm slowly learning about these boats, but still very new to it all. Thanks for any help!
