I obtained a Lighthouse 1501 windlass
installed on the 1987 vessel I purchased in 2003. Within the first year of operation, the windlass locked up and failed. I discovered that the windlass had been installed in 1995. Because I lived in southern California
at the time, I contacted Lighthouse in Riverside, California
. They requested that I ship it to them and they would inspect it. I drove to Riverside with my motor and spoke directly with the owner of the small company.
As it turned out, the magnets that lined the interior
of the electric motor
case had become broken and separated causing the pieces to block the rotor from turning. They had run out of spare magnets for the style of motor that I had and they were no longer available from their supplier back east. My only option was to buy a newer motor from Lighthouse at about $650.00. The newer motor is wrapped in a layer of Kevlar and has a few other features that the older motor didn't have.
Apparently, whoever had installed the Lighthouse windlass in 1995, on my boat
had not put a bead of silicon around the down tube that the motor attaches to with the three hex screws. That little oversight allowed sea water
from the anchor rode
to collect on the top of the motor case and eventually corrode the upper seal of the motor. Sea water
then flow into the motor interior
where it caused its damage. It was then a matter of time before it caused the sealant
securing the magnets to the inside of the case to corrode and break down. That allowed the magnets to pull away from the case interior and jam against the rotor. Lucky me...
They are very strict about how the motor should be installed to insure long motor life. The bead of silicon is crucial to the proper installation
and long motor life.
The folks at Lighthouse are very knowledgeable and helpful.
Good Luck and fair winds!
