    are these things even worth it???

    I did something similar to my truck and it gave me more horsepower and better mpg on the highway but worse in town, now they have it for seadoos?

    $40 for a resistor and a pigtail wiring harness is kind of pricey... Ron

    When you add performance and HP through better breathing and fuel mixture, or better mapping, you are working within the contraints that the engine can handle. You are making it more efficient. But when you begin adding resistance or 'boosting' to a motor without major adjustments to the components affected (pistons, VALVES, bearings, lifters, etc) you run the risk of over powering these components.

    Most are designed with a %'age 'overage' in demand...example, a valve might be designed for compression of 125psi, but can effectively handle 20% more than that...say 148 or so. But not all components can handle the same %'age increase so you risk something giving out that is VERY costly.

    If you want to do this - be ready to upgrade components as well - and if you are going to do that, you are better off just putting a Stage I or II kit on the ski as it's designed for what you want.
