Ideas For Jet Ski Seat

[Mike]

ive done  many snowmobile seats that in the seat hey didn't have strings but used 1" webbing pulls

Yup mike I see that all the time. I've had to add new ones where they didn't exist too. Sew that gusset sorta thing to the seam then webbing to the gusset, then cut a hole in the seat (I've used a router bit in a normal drill before) and run the webbing through the hole. I've also stitched string like jojo says. Slow but it works. I threaded the thread through a hole in the seat pan if I can. Then you can play with the depth as you play with the skin instead of doing it first.

I'll throw my 2 cents in here. I did threes jet ski seats from bombadier jet skis. they were all one piece seats with the seperate  knee leg comfort piece just below the helm/handle bars. I used seaquest vinyl from Manart. Seats - easy peazy. Slight heat, little stretching, stapled them down. The comfort pieces - pure hell with regular vinyl Lots of heat, plenty of stretching, had to do one twice, had to put them on a certain way, took two people. Next time, ill use All sport or some other stretchy brand of vinyl.
