    Do you know what kind of GPS he used? I ask because I have a Garmin Legend. It says it's water-resistant to 1 meter. Think it's safe to put on a laynard or float and give it a shot??

    I would take a guess at the 550 being around 43 hp and the 650 53 hp. I think I am erring on the conservative side. A 440 is 35 I thought. OR was the 300, 35 and the 440, 33 I always heard stock 300's could beat stock 440's.

    Back in the day when I had my X2, it used to run about 47-48 (in 89') and their was a guy with a tricked out 300 that used to pull on me. He had no holeshoot but he used to pull 51 on the guy (that use crazy).

    I'd be totally shocked if any stock 650 in any hull went over 50mph. My first ski was an old race ski ('91) and I was told it was a 50mph boat when it was raced. Not sure what was left on and taken off when I got it, because I bought it off of someone else and the carb at that point was a 28mm mikuni, which was smaller than stock, so it obviously got yanked off before being sold. It still had a milled head and PJS pipe though. I got radared once and was lucky to pull low 40's AFTER putting on a 42mm carb.

    I figured I was doing close to 50 with my limited (except stock compression) 650 w/ a 17* impeller in my 550 hull. They (kawi) say a stock 750sx would do about 48 and I could keep up and sometimes pull away from my friends. When he milled the head and put a Factory Pipe on, he could take me again.

    the 300's do have more horsepower stock than the 440 but the 440's can be modified to a higher output frame than the 300's, however yes it is true that the 300 stock engine produces more hp than the stock 440. I know it's difficult to believe and everything and hardly no one can get it though their thick skulls as to why but it all has to do with the size of the piston in the 300 and the crank, basically the overall internal physics of the motor as opposed to the limited output power of the stock 440.

    the 300 also uses a reed valve where the 440 didn't. That probably makes some difference too.

    Brian, I don't think the boat kicking you off has anything to do with damage. I was talking to a local guy here who had a conversion boat. He was telling me that it had a bad tendency to throw people off as well.

    I also noticed that there are some differences between your diagram and mine. I wonder what sort of difference it makes... I know the diagram I have has been used successfully. And I know yours has too.. But there is slightly different wiring...

    I noticed some differences as well. Not sure what they are. You don't show anything happening to the 2nd yellow, it just stops. The other dilema is what the black and the black w/ yellow wires do. It's possible they are all grounds and mine is just showing how they come together. Your diagram leaves the exra wires out, I included them in mine. It's been too long now since I've looked at these parts to remember what is what.

    I think the info came from the same source as jetcraft is who I bought my conversion plate from, but they left the diagram out, so I had to call to get the info and then when someone asked I drew up my schematic. So, I'd suggest someone using yours, unless someone can clarify.

    Come to think of it, I think the black w/ yellow may be a ground, in which case mine might just be showing more than necessary. I'm sure the yellow wires are dumpicate as well, so maybe they don't need to both be hooked up. I know on the 550 the orange wire goes to the same exact place and when doing the re-wiring, a few of them can be eliminated.

    MAYBE SOMEONE CAN POST THE SCHEMATIC OF BOTH WIRE DIAGRAMS FOR US TO COMPARE!! HINT HINT!!

    And on the kicking off subject, I think you might somewhat be right, but I don't think the damage helps matters. However, I was in Florida a year ago and did some more damage the the rear extension caps on my 550 hull and it did somewhat level the boat out, but probably slows it down a bit at the same time, because of drag.

    I already emailed you but ill let everybody else know on here for future reference

    -You need flat headed bolts for the conversion plate
    -you need the 550 coupler off the motor, a 650 coupler wont fit!!(dont put the washer that came off the 550 on the 650)
    -your going to have to make a custom bracket for the throttle lincage to the carb
    -Your going to need the fuel pump from a 650
    -I suggest a primper kit cause its really hard to set up the choke
    -I just bought a used 650 wiring harness (real cheap)
    -Also the fuel lines are pretty easy set up, theres arrows on the fuel pump pointing to the pickup and carb

    Hope that helps

    ALSO the 440 PUMP is more desirable than the 550 Who would have guessed!?!?!

    HA, ill put my "440" up against any squarenose on here!!
