Does my motor need to be raised?

[whitetailhntr]

Seems like my motor sits to low?

 

[whitetailhntr]

It's on a 14 flat bottom with a 15hp johnson

Should the cab plate be level with the water?

Cav plate

No - the cavitation plate should be level or just below the bottom of the boat.

check the write up titled "Transom Height" down just a bit on this page:

Great thankyou

 

[whitetailhntr]

Should I go up more?

 

[Clint KY]

Nope - that's just fine.

It's more important to see the position of the anti-ventilation plate while you are on plane.

 

[turbotodd]

Raise it until it either (1) ventilates, or (2) loses water pressure. Without a hyd jack plate, it will probably ventilate (blow out) before it loses water pressure.

 

[whitetailhntr]

What's the motor do/act when it ventilates?

 

[Zum]

Looks like a good starting point, you may have to go up or down still, depending on how she handles.
Different hulls, motors etc.,have different heights.
Like mentioned above, just make sure the motor has a good flow of water(pumping good).If you go to high you can lose your water pressure(not good).Your rpms will increase and your prop sounds like it's out the water, when ventilating.

 

[whitetailhntr]

So I assume losing water pressure is referring to the impeller pumping water?

No ,it is fin, as you run the cav plate needs to be just under the water or, you wont get lift and good control Hope this helps

Great thanks fellas I think I found the right hole/height to run my motor. Got up to 22mph yesterday.
