I am thinking of re-powering my 1996 Lund Tyee and no I am not planning on replacing the boat. The tag indicates that the maximum HP rating for the boat is 140 HP. I am thinking of re-powering the boat with a ETec 150 or Verado 150. Do you think it is a good idea to go to the 150 or should I at or below boat HP rating? The new 150 Tyee is rated at 175 HP max.

Any reputable dealer will not put on anythhing that is over powered. It is a big liability for both you and him

The coast guard will say no.
Your insurance company will likely say no.
However, it is difficult to find a nice 140 these days and there are lots of very good 150s out there.

From a weight, handling etc. there is very little difference.

You make the call.

I'd call your insurance agent first. If they go along with the "over powering", go for it. But, why not hang a 135 Verado on it, and stay within the limit? Dang near the same motor as the 150.

dont waste your time for an extra 10 hp. You most likely wouldnt notice a diff from a 140. I would strap a 135 verado on it. I am riunning a 175 verado on my 2008 prov. VERY, VERY, VERY impressive!!!!

Overpowering is up to you but...I came across something interesting on my 1850 reatta the other day. Now, on the coast guard plate it lists the max HP at 175. But, as I was cleaning the transom I noticed a plate behind the motor. It listed a max motor weight. I'd be interested to know if one can go off that transom plates numbers or if the CG plate is set in stone? Not like I'll be changing my motor out anytime soon, just found it interesting.

The max motor HP is a Coard Guard spec, always stated on a label attached to a boat

The max motor weight is a manufacturer spec, not always stated on a label.

You should pay attention to both, since there are consequences for exceeding either one.

I would think before I would even put some 140 hourse on a 96 model that's why the new boat's are so wide.So they can hold the extra weight of the new motor's.

I'm sure lund boats or brunswick should have that info for you It's not that old of a boat.
