Really need some input PTO? Drive shaft?

[jsun3701]

I was out romping around on my HX Today when she sounded like I grinded the gears. Alas.... no gears. So when I got home I pulled the pump housing off. Prop is fine couple nicks and burs nothing major. Then I decided to pull the motor and the shaft. The shaft coming from the motor or the PTO is spinnng fine but the shaft connected to the prop doesnt spin. After pulling the motor the shaft looks ok. The teeth in the front match the teeth in the back. I cant really make out what shape the PTO teeth are in. The seem ok except towards the back. The feel smooth in the back. But there are no bits of loose metal and I can still feel the ridges of the teeth in the PTO.

So my questions are how hard is it to replace the PTO and how can I tell by looking at the teeth on the shaft wether the PTO teeth failed or the shaft teeth did? Also is there a trick to pulling the shaft off once its disconnected from the motor? Does the shaft come out from the back or in through the bilge?

Oh and of course what else should I do while Im in there?

I know thats a lot to take in but thanks for the help!

Also my PTO appears to be almost inside the engine housing, but it has a grip like thing that would fit a huge cresent wrench. Does anyone know what Im talking about.

you say the shaft is turning behind the pto, but not at the drive? then it isn't the pto or front end of the shaft. there is a u-joint kinda thing connecting the 2 halves of the driveshaft. that is where you will find the problem.

The PTO is more or less the trans mission for a ski. It basically transmits power from the crank shaft to the propeller. I poted again with some pics and actually one of my videos is in the vid section, on youtube.

it is direct drive. by your description, everything between the the back piston and the impeller blades is the transmission. something is broke. you took motor out. you took pump out. both ends of the shaft look ok. the coupler in the middle, which is inconviently hidden in the middle of the gas tank is the problem.
