Can I Drill Holes in the Winch Housing Instead of in the Boat to Install a New Winch?

Question:

If I am replacing a Fulton K650 with a F143100 can I drill holes in the winch housing to accommodate the current bolt spacing instead of drilling in my boat?

Hi Pete,

I don't recommend drilling holes in the winch's housing to match the other winch's bolt pattern. The housing is designed to handle a lot of stress and adding new holes or drilling over existing ones would create stress focal points that could cause it to crack or bend.

Most people switching from the Fulton K650 to F143100 build or buy a heavy-duty spacer plate, usually made of 1/2" to 1-1/4" thick starboard, marine-grade aluminum, or dense hardwood and bolt the spacer block into the boat's existing holes. Then you can bolt the new winch into the pre-drilled holes in the top of the spacer block.

What kind of boat are you installing this winch on?

@PeteM Happy to help! I love sail boats! My uncle had one when I was young and I got to go out sailing with him when we visited. Accidentally hit my father in the face with the boom when I was learning to steer it though.... :/
