From Martec to Campbell Sailor

Removing the Martec and installing the Campbell went pretty well. In fact it only took 10 minutes. I was anticipating all manner of problems.

The "nut" that holds the center section of the Martec to the shaft is the cylindrical thing on the end of the "T" handle wrench in the middle of the picture. It has a hole in the end that a 1/2" drive fits into. You remove 4 split pins, two for the big pin that holds the blades and two to keep the nut from turning. Stick a 1/2" drive into the hole in the nut, and apply force. I used a monkey wrench to hold the shaft.

I picked up a gear/wheel puller from Harbor Freight for $15 and it made quick work of getting the Martec's center secion off the shaft.

Putting the Campbell on was even easier. I re-used the key, greased the shaft, and slid the prop on. Two nuts and a split pin and you're done.
