Well, the threads are all in good shape. I was reading a thread on this. Someone suggested grease on the threads would make it seem tight but then come off when the ski reved down. I do remember the treads being greasy. I wiped them off but never actually cleaned them because I was saving my...

Running into an issue. Never, in 15+ years had this happen to me. My prop keeps spinning off when out of water and I kill the engine. I have changed hundreds of props and never had this problem. The shaft doesn't wobble and the prob was just balanced by Impros. I cranked it back on...

Hold that thought. That's exactly what I'm up to.

Here you go

Fired her up today. She sounds good. Had an issue wit the prop but fixed it no problem. Revs very quick with the new pipe and carb. Just need to glass the top of the rails and re-turf. Hope to put her on the water tomorrow for a quick test before we ride Sunday.

Yea, someone here told me it was in Houston's CL.

On a side note, the paint on the inside was absolutely mint until my best Jackarse friend decided to thin the split oil with paint thinner. Thanks buddy :icon16:

This was before I actually secured it to the hull. It still sticks out just a bit but it's now flush to the hull. If I feel this effects the handling, I could modify it a little. I had this same issue with my FX-1 mod. It didn't seem to cause any issues there. The shoe is firmly attached...

Here's a pic of the intake grate. Its a kawi 650sx grate. Believe it or not, it fits perfectly with no modification at all. It turns out the 650 pump cavity is about 2 inches longer than the 300sx. When I tried this out, I was shocked to see how easily it bolted up. Not only that, it fits...

I've never heard of advanced but I have spoken with Group K and am comfortable with their work. Hopefully they remember what to do. I'm not sure that they've had many 300s to mod. LOL

Here are the three most critical parts of this conversion. Thanks to the aftermarket kawi style coupler, I can now add virtually any motor I like with the right adapter plate. The prop is a 15/18ss prop from a VXR pro. I sent the prop to Impros who then cut it down to the FX-1 diameter and...

Not yet. Right now it's all bolt ons. 38mm carb, Pipe and dual stage reeds. We'll see how much that helps this weekend. After LSFR, I'll be sending the head and cylinder yo Group K to see what they can do. Soon as thease photos upload, I'll post some picks of what I've done to make this...

Thanks for the input WFO. Mine already has the boost bottle. What the heck dose that do? I was going to block it off. Maybe I shouldn't? You told me about the gasket before. I may do that before I have Group K modify the porting and head. They actually redesign the head dome for $40. Not a...

Spoke with my engine manufacturer today. The smaller engine is closer to being a reality. There is a possibility of a 40lb motor with 60hp. That's basically a single carb 701 that weighs 50lbs less. The larger engine may be a while. As for the actual ski, I got the engine and pipe all...

Thanks for your input and your interest guys! Vibration could be an issue. That's why I'm not lightening the flywheel. Keep in mind, this is only a prototype. So, if the hull cracks, we'll just make the production hull stronger in that area. Plus, the motor we are planing 0n utilizing will...

I imagine it will weigh about the same. Stock it is 220lbs. The pump is about the same, the modification I had to do to the mid shaft is slightly heavier. So I guess it will weigh about 222 when complete plus gas. The 300sx was the smallest ski ever made. Hopefully with a little power, it...

Dony get me wrong, the ski is extreemley nimble like the FX-1. Its just less likely to throw you off suddenly for no reason.

Actually, it's like a tiny, super light SN super jet. Its extremely stable, it carves relatively well, and it rides pretty flat. It also flicks around with ease if you want it too like an FX-1. I had no problem with it porpoising and it didn't seem to want to buck me like a 550 or my FX-1s...

OK, I've looked into everyone's take on how to build the best 300sx. I've studied the BOB, WFO's project, and many others. I recently purchased a bone stock, nearly mint 300sx. My first impression when riding it was "what a turd!" Of coarse I'm pushing 190+ pounds. So I didn't expect it to be...

Nope. Its not Kawasaki pump. I tried a 550 pump. The 300sx shaft and midshaft housing are 300sx specific. Too much machine work involved. This required a little out of the box thinking. Keep in mind, I plan on using the 300 engine. An SJ pump would be to big for this tiny motor. The...
