Hello, Im new to having a boat. I have a 14 foot jon boat. The previous owner put a electric tilt and trim plate on it. the plate has the motor sitting high. High enough that the the prop is almost at the level of the bottom of the boat. It has to be trimmed way down. is there any ideals on ways lower it without taking the Plate off of the transom? Thanks.

Sounds like a an electric jackplate. Are you certain it doesnt have up and down ajustability?

I cant see a way out here. There should be optional holes in the plate mount so atleast yo can use the existing holes in the transome to make your adjustment. If not, add holes to the plate yourself. Whats stopping you from lifting the motor off and moving the plate? A couple hours and a tube of sealant. Cant be too heavy a motor on a 14' jon. It'll be well worth the effort.

So the holes that would be there after I remove the plate. I would just fill them marine sealant? Like I said this is all new to me man. I was actually thinking of trying to add a lower plate to the existing plate just lower. Don't know if that'll work. I'll have to think about it for a few and see what I can do. Thanks

Post a picture from the SIDE ( prop level ) so that helpful folks can see the position of anti cavitation plate relative to bottom of the boat.

Yes, do this with the motor down and pics showing the plate with the motor up. We cant tell for sure if the motor is to high or there is another issue.
Have you run the boat? Jacks are designed to allow the motor to be mounted higher.
Other than that, yes, you may have to fill old holes and drill new ones.
The other option is to drill new holes in the plate itself that match the old holes already in the transom. I believe this an installation link to your jack.

It looks just about right to me. With the motor set back that far on the bracket, it is logical that for optimum performance you would mount it higher.

If the hole shot is good and it planed well, simply don't trim it up. If for some reason you WAN'T to trim it up, re-drill the holes in the bracket and lower the bracket so that the AV plate is level with the boat bottom.

Jon boats are used in shallow, rocky rivers. The jack plate is simply there to raise the motor up to facilitate running in shallow.

Its not a jack plate. It trims and tilts only, no vertical lift.

The pictures were not taken from the correct angle, but it looks like the AV plate is a couple inches above the bottom of the boat.
