How did you get the 650 pump in there??? Pictures please.

i don't have any pictures of that but it was a lot of work. i sectioned the pump tunnel out of a 650ts and the cut the tunnel and tray floor out of the 300 and glassed it in re foamed the inside then ran carriage bolts through the deck to act as studs for the pump.

if anyone has a good deal on a 13-18 impeller for 650sx let me know

you should go for a sxr cut back impeller while your at it.

what drive shaft is that to set the motor back so far?

footholds riveted in side reshaped just need to glass it all in. trim ready to go on. quick steer plate on.

That is going to be interesting with the engine set back that far, I ended up using a 750SXI driveshaft on mine to set the engine forward, you have a serious risk of being way too nose light on that ski, if backflips are what you are going for you are on the right track though.

thats somewhat the hope, but we will see if i have to move it forward than i have to move it forward ya know..

I understand clearance gets tight running the longer shaft as I have , I built mine for my son and wanted it well balanced and ridable for him, moving the steering forward is probably the best thing you could do on that ski, mine is moved forward about three inches.
