Post Boat not planing
I have a 1658 riveted jon boat with a modified go devil 23hp motor on it. I rebuilt the motor from the ground up and really happy with it's performance so far.

Biggest problem I have is the front of the boat always seems to low even with just me in it it's pushing water up front. If I move as far rearward as possible I gain a mph or 2.

As far as weight on the boat there is nothing up front, motor and gas tank are in the rear.

Anyway to adjust the motor/boat to raise the front of the boat up? I know on a outboard I'd just adjust the trim but not sure what I have for options on this motor. Thanks Dan

Sounds like the only solution you're gonna have with that combo is to cut the transom down some to lower the mount point so the motor doesn't lift the rear/lever the front down as much.

Check for a hook in the bottom just fwd of the transom. A very small hook will cause what you describe, especially with a boat as wide as yours and the limited torque of a longtail.

Transom is 16in tall.

No hook in the rear of the boat except the weld line at the end.

Yeah, fill a few sandbags and put them in the rear of the boat. You have a problem few have ever experienced. Rake is too short because you have so much lift with the wide and light boat. Most of these boats never experience a problem with the rake being too short.
