If I were you I'd stay away from the Chrysler. Never met a Chrysler boat boat motor I liked. I once talked to a boat mechanic that said a "a Johnson\Evenrude is like a Timex, a Chrysler is like a sun dial". Just me... if you want more hp, keep an eye out for another boat with a motor in the hp that you want that works. Switch the motors, sell the boat that you don't want and you have a free upgrade, sort of. Seems you can get a boat/motor/ trailer cheaper then a motor.
