1969 mako nosediving veering right

[evilwind1]

I posted this question on another forum but will try here also; my '69 mako 19' CC I just purchased planes off and then goes into a mostly nose down mode and tilts to the right. I tried tilt trim adjust. weight dispersal and trim tab adjust.,doesn't change anything I feel it could be the slight downward hook in the back bottom of hull. Boat sitting about 2 ft. off back of trailer. Any helpful info would be greatly appreciated!

You are experience "bow steer" from the bow being too low in the water. I've had this happen to my 20 a couple of times in very choppy water, and if you have a "hook" in the bottom of your hull from the bunk boards not extended PAST the transom as they should then it is in effect acting as trim tabs forcing the bow down. You can try and trim the motor up and maybe putting a doel fin on it, but the true fix is to correct the hook in the hull.
