prop depth?

[kneedeep4829]

I am pushing a 14' double wide with a 92 johnson 25hp motor. I am not sure if the prop is at the correct depth. If 2 people are sitting in the back the boat will not plane out and the prop will eventually free spool as if I have spun the prop. If there is to much weight in the front it will do the same. Shouldnt this motor be sufficient for 3 people? Any help is greatly appreciated as I am new to this outboard set up.

Ayuh,.... Welcome Aboard,... The plate above the prop should be even with the bottom of the hull...

Never heard the term "double wide".
There is a possability you have a spun hub in the prop; but check the antivent plate (just above the prop).As bondo suggested check that it is about even with the bottom of the boat. You can use a straight edge along the keel to check the demension.

Re: prop depth?

the antivent plate seems to be in the right place... the prop is not spun. once we get on plane she runs wide open.. a little water sprays up.. none gets in the boat though. any other ideas? just seams like 25hp on an aluminum boat should get 3 people along pretty good.

Whats your prop pitch?
Might be to big and maybe your not getting wide open throttle.
A tach is about the only thing you can use to see if your running at the right rpm range.
"Tiny tach"'s are a resonable price...
Without going to crazy maybe someone you know has another smaller pitch prop you can try but like I said earlier would be nice if you had a tach.

Re: prop depth?

Your first post said the prop is spun when loaded "will not plane out and the prop will eventually free spool as if I have spun the prop. If there is to much weight in the front it will do the same."
Sounds like a spun prop!

Is the motor running on all cylinders?
Check the condition of the plugs, do a compression check.
Does the boat have homemade decks, bait wells etc?

A good running 25hp on a 14' doublewide jon should have no trouble getting up on plane.
