With the jack plate you are moving the motor back and on a boat that short it makes a difference. You could try kicking the motor in more, or try getting your weight out over the bow to get it planed off, but I'd try it without the jack plate first and see if that helps.

i thought the jack plate would of helped plane better no its about 6 inches back u think it would be better without it

aahhhh no the jackplate is making it worse, moving the motor back really hurts you getting up on a plane....

That thing is so short that even if you got it planed off, with the motor that far back it would probably porpoise like crazy anyway...

Lose the jack plate for a start and then get some more weight forward and it'll be fine.

i measured it today its 3 inches back i have to keep the engine up because its a 15 inch transome and the motor is a 20 cavatation plate is even with botton of boat, and yes i can get it to plane leaning over front and it does porpoise would it help if i drop the motor down a inch or two
