    Assuming you have the boat paid for and is bone stock as is. You would have to get the packet of info for 750. You would have to send your motor to Montana to Lowell or to TJ in South Florida to be machined (Ported and Bored to at least 84mm-basically to a 1300cc)--that's just under 2k. You could still use your stock head and stock carbs if you wanted to (to save some $$$).

    You would need to get a Ride Plate (lets say 130 bucks) and then have to send it off to get machined and angled correctly (125 bucks from Jim in Tampa). Then you need to buy an aftermarket intake grate (preferably a 1200 grate and an 800 grate- lets say 130 for the 1200 and 150 for the 800 grate). Then there is the aftermarket prop which is another 225 bucks an more money to get it custom pitched to your specs needed (assuming you do not convert to the 2005 pump which is another 300 bucks in parts).

    You could keep your stock sponsons and stock trim tabs technically (to save some dough as well). Then there is the pump seal kit (say 70 bucks) then there is the d-plate that you would need (say 75 bucks). Since your not fuel injected, that means you don't have to buy the 300 dollar controller and an 80 dollar air filter.
    oh, and dont forget the nando reeds which will help a bunch (i am guessing the price on those is about 700 bucks)

    I know, I know - there is a stage 2 kit on Riva's site for 1,900 bucks and promises 70-71 mph. It will not happen. Don't buy any of that stuff from them- they are trying to pay off that huge building they are in right now. Just stick with the R&D Parts. Besides, R&D makes most of the stuff that Riva sells. Stick with the guys on this forum - its the best "customer" service you could ever ask for. If you ever invent anything, sell the shit to Riva and they will market your product for you - they are great at advertising.

    So lets break this down (and if your on a budget, then this will get ugly fast---but your boat will be fast). I will break this down the cheapest way with the least amount of parts to get it done.




    Boat- say its paid for
    Information - 750.00
    Porting/Milling/Boring/84mm Pistons- 1,800.00
    stock head - N/A
    stock carbs- N/A
    Reeds - 700.00
    Ride Plate- 130.00
    Ride Plate Machining/Trueing/Angled- 125.00
    Intake Grate (say both the 800 and the 1200)- 280.00
    Prop- 225.00 (say your keeping the stock pump)
    Pump Seal Kit- 70.00
    D Plate- 70.00
    Prop being custom pitched - 50.00
    Tim tabs- N/A
    Sponsons- N/A

    Grand Total- Aprox. $3,975.00 (if you do the installation yourself)
    If you want to have someone do it for you with all the parts--?? Who Knows.

    RX951 is really close to that number. Perhaps you should get with him.

    Also, remember that most reported numbers are peak speeds. If you want a "consistent" peak speed of 75, you are probably going to have to do as big John is describing. There is a lot of work involved.

    Or you could just hook it up to back of your truck! There's not a lot of work there.

    You must be one of the young ones on here. Just think having to walk to the truck then back the truck up and line it up and get out and walk to the back of the truck and move the trailer so it is exactly lined up with the trailer hitch ball then lower the jack so it is over the ball then close the latch then put the lock on it then hook up the lites and hook up 2 chains and wallk back to the truck and make sure your lites work then take off and go that fast. Man that is a lot of work.
