I'm not sure about a Johnson lower unit but a mercury water intake is 3'' to 6.5'' form even with the pad. If this is your first Allison I would first check the prop shaft with the pad to see how far below you are. And like Big Johnson said have someone check to make sure your running on all 6 or you can do it your self by checking the spark. I have owned 8 Allison's and would never run one without a low water pickup not saying you can't do it but I wouldn't.
What color is your Venom

I checked the how far i am below the pad. Did not measure but it is a long ways from being even. I am going to try and raise the motor this weekend and see what happens.
The boat is white and red with black tips, to the poster that asked. Just like the one in the picture

Anyone haven any idea how to raise the motor via the stock Allison jackplate. The JP has two bolts on each side in the grooves and one bolt on top of each side of JP. Is it as simple as turning the big nuts on top of the JP or do I have to loosen the bolts on the sides first. Do not want the motor to just fall because I did not do correctly! Right now I think it is all the way down.
What size would the stock manual Allison JP be? 10"?

Loosen the 4 large bolts on both sides of the Jack Plate about 1 full turn . Then the bolts on top will adjust the heigth of the motor up , or down .
Before you get started , take some measurement of both sides of the Jack plate and index it with a SHAPY so you are sure you keep it even .
Aslo , spray all the hardware real good with some type of lubricant before you start turning any ot the bolts or nut .
This will help prevent them from gawling and binding up . There's nothing more agravating then turning a simple job into a major project , because a stainless steal bolt binds up !!!
The Allison in my Avitar , is my old XB 2002 . That was a Fine Boat , and enjoyed many good times in it !

If I was you I would find some level concrete, then take a short level and level the bottom of your pad, then level your prop shaft. Then I would measure from the concrete to 3'' in front of the pad lip, then measure up to the bottom hole on your water intake. That should give you a starting point.
Just guessing I bet your so low your skeg will hit the ground when you try this.
If you dont have enough room on the adjustment part, you will need to move the motor to another hole. Do you know which hole the motor is in.

It is in the one hole. The four bolts on the manual JP are all the way down in the slots on both sides. Does that mean is adjusted all the way down or up? Just asking before I start messing with it. I would seem to me that the bolts being down like they are means it is all the way down and need to be raised up.

That is all the way down..... Just make sure you have at least 14 lbs of water pressure running wide open. I would watch my water pressure and raise it until it starts going down, you should be able to run it on the bottom two holes.
By saying one hole do you mean the top hole.
