I posted this earlier, but no replies...Am I doing something wrong?

I just got a New Tracker Grizzly 1860. I have a 60 HP Mercury on it and
I'm having a problem getting it to plane off. It wants to flop up and
come down hard on the water. The dealer says the motor isn't getting
"under" the boat enough, which I don't doubt. My question is, What is
the best way to solve this problem? The dealer says it's a problem
inherant in flat bottom boats and hard to fix. Any help or Information
would be appreciated!

Call and send a followup letter to Tracker, stating your safety concerns.
They should hop right on the problem. I would see if the motor is mounted
high or low. Where is the cavitation plate in relation to the boat bottom?

After you sort out whether or not the engine is properly mounted...

try 1. moving some weight around. Moving weight forward should help. You
might try putting a few sand bags in the bow to see the effect, without
doing any real reconstruction of your boat.

If that doesn't do it, then you may want to consider tabs of one sort or
another. I added Smart Tabs onto my 16 ft. Carolina Skiff ( they don't make
boats any flatter bottomed than that! ). It made an unbelievably big
difference. I never have "bow up" and I plane out like the dickens now. I
did have to fool with the motor's manual trim pin position to get it just
right.

I know that make them in various sizes and have some sort of mounting kit
just for aluminum boats. Bass Pro Shops stocks them, at least in Houston TX.
They have a website, too.

Aftermarket hydrofoil tab might help. StingRay is about $40 US.

Trim in. (Will that motor do that? I think so.)
