Did the motor come with the boat as a package or added later?
The motor a 1999?
Pictures of the rear of the boat??
Thing that could make it lean>> motor not straight on the boat, boat not loaded properly, the trim tab on the bottom of the motor not installed right.
Load: Fuel tank and battery mounted on the same side as the driver.
Trim tab setup: if the boat pulls left then the tab needs to be loosened and turned to the left(as you stand behind the motor)
Self leveling tabs help in minor cases of lean.
The hydrolic ones help but I don't think they should be used on such a small boat??
Contact Bennett Trim tabs and they can give you the info on that.
