The engines (Optis) weigh the same. The price difference is $700. Insurance might go up only a couple bucks over a year. Top end is NOT a factor. Anything else to consider? Resale?

Resale, hole shot, cruise the same speed at a lower RPM, thus burning less fuel, higher top-end speed if you need to get in fast I see no minuses for the 115

Wife said 'okay' to the extra $700 - chicks must dig more ponies...

Is there anything I am giving up? Anything I can't do with the same engine with less HP?

Other than a few extra Coors Lights, I don't think you are giving up much. BTW, you have a nice wife.

Go for the ponies-
Ever had to out-run a thunder storm?

IT WOULD DEPEND ON THE CONFIGURATION OF YOUR BOAT. TOP END WILL NOT VARY MUCH UNLESS YA HAVE A BIG LOAD. THE HEAVIER THE LOAD IN THE BOAT THE MORE DIFF. YOU WILL SEE. THE 90 PROBABLY WILL GIVE YA ANOTHER 1-1 1/2 MILES PER GALLON OVER THE 115. SINCE YOU ARE NOT CONCERNED TOO MUCH FOR TOP END I WOULD GO FOR THE 90. MY .02
PA (AKA) ALMAR

Can not see a 90 getting 1 - 1 1/2 more MPG than a 115.

Ever gonna pull a skier, tube, etc? (if the fish aren't biting) If so, the extra horses are a huge benefit.

Gas mileage shouldn't be an issue between the two motors, especially with the Opti's!

If there the same weight go for the ponies, better to have em and not em....
