So I thought that by adjusting the cable tensions I fixed the clicking problem.
I was wrong. During my last weekend's Rappahannock Trip I decided to take the same drive to make sure that everything was working properly. A few miles after getting on the water it started clicking again. 10 miles down the river the drive did not feel correct. I tried pulling out the drive but could not.
I reached under the boat and could feel about 4 inches of metal shaft sticking out the back of the drive at the hull level. With all the gear I could not roll the boat. Luckily we came up to a large downed tree trunk laying at the edge of the river. I pulled the nose of the boat up on to the trunk like a giant car jack and tied the bow off to keep the boat from slipping back into the water.
I was able to get under the boat and drive the pin in to remove the drive from the well. What happened if the Allen screw that hold the main support shaft for both fins had loosened up allowing the shaft to slide back. I carry various drive parts and some tools to repair a drive on the water. Allen Wrench needs to be added to my inventory.
Lucky for me the person I was with had a spare drive.
