    Driveshafts

    My first '94 SL650 (Sleeper project) came with a rubber PTO coupler, while my second '94 SL650 (Julie's ski) came with a solid PTO coupler. I figure that the first one had been 'upgraded' at one time. The driveshafts are slightly different between the two. Since I want to change the Sleeper's coupler back to the solid style, do I need to change back to the original style driveshaft or will either one work? If worse comes to worse, I will just swap the two PTO couplers and driveshafts and call it done, but would rather not have to try to remove the coupler from the second ski if I don't have to. I do have an extra solid PTO coupler coming in one of my box-o-parts! Here's some pics...

    Why?

    The rubber bonded couplers can handle the 140+ HP of the 1200 engines.

    Other than reducing driveline vibration, and a little more rotating mass, there isn't much downside to you using the rubber coupler.

    Rotating mass...that's the reason. I am installing a Jetinetics flywheel and it seems silly to me to leave on the heavier PTO coupler at the other end. With the lighter flywheel, lighter pistons, and the lighter PTO coupler, it should rev up faster and give a better holeshot!

    Driveshafts can be interchanged with no problem.

    You may want to put the rubber dampned coupler on her ski though if it takes out any unwanted vibration.

    Hmmmm, on second thought, she may just want the solid coupler left in place!!!!!

    Seriously, you'll never, ever notice the difference in weight between the two. A lighter flywheel will make a much larger difference than a lighter coupler, due to the location of the weight. I hated the solid coupler on my 1200, but had to run it because it was close to [email protected] and destroyed the rubber ones. But like xl said, you can run either driveshaft with either coupler.

    Quit with the shaninigins and start building! lol My eyes loose vision everyday and I'd like to read about the final ending to the skis!


    (I'm kidding!) So you can use either,? they look different to me. does one go with the solid coupler? and the other with the rubber coupler?

    Rubber dampned coupler is longer, so it has longer splines.
