    Custom/Hybrid Melmack's very unique 300sx build

    Thanks for the info friend of mine has been building ski's since the 70's and he said he's got some specialty tolls for removing 440 pumps. The prop says kc 10 16 on it I was told it was a solas but I'm not a expert so maybe I'm missing something. As far as the pump I have have had people tell...

    300/440/550 300 sx timming mod

If I prime the carb it will fire back up run for about 2 min and die again. It has a 38 sbn that I took from a...

    300/440/550 300 sx timming mod

    Thanks for the info I'm putting a 650 pump in when Install the engine. I have a prop its a solas 16 10 I'm reluctant to try it because I think its more of a top end prop but I dont really know prop pitches so I could be wrong

    Yeah didn't think of that if you cut up a hull and glue in the mounting area your raising the engine the thickness of the glass. Damn why can't things ever be super easy

    Custom/Hybrid My 760 SX (A 300 SX transformed from a SJ)

    I don't mean to hi jack your thread but if i were to use the poly adhesive could i just grind down my 300 mounts clean carefully remove my 650 mounts and glue them into to the 300 hull? If this is the case what is the brand name of the glue?

    Custom/Hybrid My 760 SX (A 300 SX transformed from a SJ)

    If you use the stock handle pole and mount it in all the way forward are you gonna lengthen the pole? I just shortend my handle pole 2.5 inches and now I feel way to bent over and uncomfortable on the ski. I don't think I would be able to ride it if it was any shorter.

    Make sure you take plenty of pics of the handle pole I'm planing on copying you. I just need to learn a little more on why and where i want to mount it before I start cutting my ski
