    Default 26' commander cat stock 496HO

    Since I owe more than I think I can get for my boat I cant trade/sell to up grad on a new boat.. So I have recently been looking around on what I can do to my boat to get some more MPH. My goal is to hit 80, currently I can get 70 max on perfect conditions. I have just recently heard about blue printing, not sure what it is and getting a lab prop. ( current prop is the stock 4 blade that comes with the 496HO ) Anyone care to point me in the right direction on what I need to do to hit the 80s and a idea on the cost? Anyone knwo of any good boat performance shops in Lake Havasu City?

    Thanks

    Unfortunately it's going to take a lot more than prop work to pick up 10 mph. On that boat propshaft height is critical also. To get 10 mph your going to need 100 to 150 hp more (depending on many thins such as open bow and propshaft height).
    The amount of power increase you will need depends on how far off the boat currently is from the optimum setup.

    Which is what I thought. It is a open bow/ walk through. I had been toying around with the idea of putting a Procharger or Whipple but it sort of makes me nervous. I have never had a problem with my engine so far and I have about 35 hrs on it. I hear about people putting on one of these chargers and destroying there engine. Like I said my goal is 80 mph but I will take what I can get. This will be a work in progress thing so I'm just looking where to start, or if I should start I guess haha.

    Pro charger is the good way to get the power. You need boost to make those kind of numbers with that motor. Motors are usually built for the higher boost, forged internals, lower compression, larger cams.

    Pretty sure any good motor builder can tell you everything you would need to know and what it would cost, considering your motor is still new.

    His engine is not a custom built engine designed for boost at all. It is a Merc 8.1 and the internals are anything but heavy duty. The stock 8.1 will live with low (4 and under) boost, but it will reduce the engine life. The pistons, rocker studs, rockers, valve springs, etc. are not boost friendly.
