    Looks like you already got 'er done, cudo's!! For future reference tho:

    Preheat 5-600 degrees, if possible weld with a nickel/chromoly rod (such as Arctec's Unicrom series) and cool slowly. If you can't find that rod, ER80S-D2 is a real decent option for MIG wire. In the mean time, have fun!!

      4140

      you can use duplex(2209) or super duplex(2507) with about 400f pre heat. It is very good for any sort of dissimilar welding

        Oh, yes.. that is exactly how is is supposed to ride. The front sponsons are there for the ride after the launch. Bottom 1/2 of the prop in the water.

              All in what you get used to I guess. It is not a beginner ski boat... that is for sure.

                BTW... if you look at the back of the boat you see a black square behind the engine. That is the parachute. Look directly in line below that and you see a black piece with a shaft going forward. That is the strut.
                SO, you can see it carries the boat weight plus a ton of side load. (from bottom half of prop)
