sticky maxprop

[Anders Pedersen]

I have a 21 inch, three blade maxprop, with which I have cruised 7000nm. The prop is driven through an hydraulic gearbox. My problem is that I have to grab the shaft to stop it turning, therebye forcing the Maxprop to feather. At first I thought too much grease in the prophub was the culprit, but the amount was not excessive.Any ideas to get the maxprop become a "feathering" prop? Should I get a little machined of the endcap.Thank you AP

Prop

My owners manual tells me to kill the engine while at full speed to feather and put transmission in Neutral. If there is any shaft spinning put it briefly into reverse to stop the shaft spin then back to neutral to sail.

Same here

I've always had to momentarily put my gear in reverse to stop the shaft and feather the prop. Figured it was "normal" behavior!Graham

Hydraulic transmission

Hello Andres,The transmission in your boat, I assume, is hydraulic? The reason you need to slow the transmission or shaft down to get the propeller to feather is to allow water to flow over the face of the blades causing them to rotate to a feathered position. I would suggest that you stop and kill the engine in forward gear when you are ready to sail. If your transmission is mechanical, just place the transmission into reverse gear when the motor has stopped and this will lock the shaft in place. www.pyiinc.com has the instruction booklet placed on it so that you can see the correct procedure. Good luck Kevin
