I built my orange FX (bad fish) years ago as a backup for my Frankenstein FX. Well, after doing a rockered nose and a 148mm pump conversion on "Franky", the orange FX felt too dissimilar to be a good backup ski.
So, with Daytona only a few days away for me, I decided to tear into it! I started 2 weekends ago by rockering the nose, then last weekend I started the pump mod. This pump conversion is comprised of an interesting array of parts. The pump is a Polaris 6 vane stainless 148, with a Waveraider tilt nozzle and Kawi X2 sterring nozzle. I used a kawi prop in the polaris pump and it uses a Kawi STX driveshaft. This combo provides a 2-3/4" setback.
My goal with this conversion was to find a way to retrofit this 148mm pump into my ski (which had a 140 kawi 650 pump conversion) without doing any glass work. To pull this off, i made a pump shoe from blowsion sxr shoe and a 1/2" billet plate.
Here's a couple pics of rockered nose before turf:
Here's the pump mod:
Here's the pump shoe:
Here's the pump with wear ring and a 1/2" spacer i machined to allow for correct driveshaft position:
The pump mounts to the pump shoe via 4 long bolts, rather than bolting to the underside of the floor like yamaha and kawi 650 pumps.
When you squeeze a 148mm pump into an FX, there really no room to get any sort of wrench or socket on the steering cable nut. I'm sure this is pretty much the same for SJ pump conversions? To get around this, I made a wrench with 2 roll pins at each end and drilled the steering cable nut to interface with the roll pins. This wrench allows for loosening/tightening of the nut with ease in what little room there is.
Here's a pic of the wrench and modified nut:
Well, tomorrow the ski will get turf on the new nose rail and then thrown in the van for a Saturday departure for Daytona for test riding. I was getting worried I wouldn't pull of these mods in 2 weeks, but it looks like I'm gonna make it!
