I just replaced the motor on my maxwell 1200, 12v electric windlass. In one week I have shaeared the shear pin twice. The first time I was pulling the anchor and just as it cleared the bow roller the pin broke. Half a day later, because of bad access, I was able to replace the shear pin. The pin broke the second time while I was setting the anchor. As I have done on every boat I owned, I dropped the anchor and then backed down on it to make sure it was set. The anchor was set and I would forward to put on a snubber line. When I try to put slack in the chain, I found the shear pin again broken.
The shear pin goes through the motor shaft and aligns in a slotted shaft in the gear housing.
I had anchored with this windlass many times before the motor required replacement. For two years I never had a problem, and then now. The shear pin is a split, spring pin that is hollow and compresses as it is driven into the hole. I am thinking of replacing the spring pin with a solid pin.
Has anyone experienced similar issues?
I am in Marsh Harbour the Bahamas and getting parts here is difficult. I was able to find similar shear pins in an auto parts store, but it broke like the first on.
Other info: using 3/8ths bbb chain and 60 pound Manson Supreme anchor. I always drive up on the anchor, never pulling the boat with the windlass. Backing down on the anchor with my 50k pound boat obviously broke the pin. However, I have used this procedure for two years with this boat, and for more than 20 years with previous boats, to include charters, with no issue. And backing down a n the anchor does not explain the first breakage.
Anyone have sage advice?
