I am looking for the size of the nut which snugs the air-mar B60 transducer to the hull. I am also looking for a wrench that you can use easily while reaching down a small opening to tighten it as well.
Thanks,
paraman

That is not a common nut one can find just anywhere. 60 x 2 threads.
The Airmar number is 02-133-01

The wrench part number is 60WR-2 for the B60 2 3/8" housing.

Gemeco sells the wrenches and the nuts. You can view their catalog at gemeco.com

I always use my hand to tighten it and then tweak it with a pair of large channelLocks.

I never use the rubber gasket. Overtightening it with 4200 will squeeze out to much of the sealant

Thanks for the info guys.
