I have a Garmin GMR 18 dome and I find that it stands out from the mast when
installing with a SC20 Mast Mount. Why is this?
This is because of the mounting footprint of the dome. If you rotate the dome
through 180° before installing then it will solve the problem and the dome will
be installed much closer to the mast.
When setting up the dome, you should be able to note through the chartplotter
which way the dome is facing. Should you have any questions regarding the set up
of the dome, please contact Garmin directly.
I require some replacement mast mount feet is this possible?
You can order a replacement footpack for the product. The part no. is 15001
for all Mast Mounts excluding M92722 (Part no. 15001R).
Can I install onto a Carbon Mast?
Please speak to your rig manufacturer for advice.
Can I install onto a wooden mast?
Yes. However you would not use the rivets as supplied with our Mast Mounts.
Wood screws have been used for installation but they are not recommended.
We would suggest making a stainless steel band to fit around at least half of
the circumference of the mast, rivet the feet to the band and then bolt the band
to the mast with a bolt that passes through the mast.
Please provide technical details of the size and type of pop rivets needed
to fasten the M92698 mount to a sailboat mast. I purchased a used mount and I
need replacement pop rivets, I can purchase Monel and stainless pop rivets
locally, however i need to know exact specs.
We use 4.8mm Monel rivets, 16mm in length but check your mast wall thickness
to be sure 16mm is the right length.
What type of paint is used on the Mast Mount?
We use colour code RAL9016 paint on all Mast Mounts and they have a
professional powder coat finish with an etch primer and top coat.
