Who is using ROTAX two piece coupled driveshaft?
Is anyone using the ROTAX two piece coupled driveshaft ? You think its a good investment over the drive shaft seal?

i am using the rr driveshaft/coupler. it provides a superior tunnel seal compaired to the stock setup, however the splines on the impeller side are smaller in diameter so you cannot use a 4 blade or other rxp prob.

So, you have to use a 155-mm impeller like what's in a 185-hp ski?... Ron

yes but you can have the outside impeller welded to fit the 159 mm stock pump.
