With you, the motor, and gas tank in the stern, you're stern-heavy. Move some weight forward.
Yep, and from your pix, it looksike you've got the tilt pin in the 3rd highest setting, thats giving you MORE bow lift. Swap it down to at least the 2nd lowest hole and try again.
Weight forward and moving the pin should each get you a little less bow high. Together it might be enough.
When I take the Admiral w me in our 12ft Sylvan, if she's on the center bench, my pin for a 5hp is on the 1st hole, as low as it will go and we do ok. If she sits up front, facing the rear, i can run a little faster w the pin in the 2nd hole.
Unless I'm solo and sitting as far forward as I can and still reach the tiller, on glass smooth water, the 5hp barely gets me on 'plane'. At 225lbs, I'm ok w that. Dont make any distance runs or HAVE much need for speed. Mines rated for a 12, but I got a 9.9hp I plan to run on the next outing. That was supposed to be over the summer :facepalm: hasnt happened yet..... :blue:
Move some weight and move the pin. Bet it'll be much better.
Good luck
