Yes, mounting a fitting to a plastic sea kayak deck is pretty easy.... place, drill, seal and bolt.!
The reason however i am writing this Instructable, is that i really dislike any thing metal and potentially "sharp" protruding into my kayak cockpit or hatch space, waiting to "bite me" during the perils of kayaking.. ( wet exits or blind hand sweeps...)
So..... while i was installing this fitting i, found a great way ( completely accidentally ) to cover up these potentially sharpie bits.... just laying around in my shed...
Image (a) My finished GPS mount on deck
Step 1: Parts Required
What i used:
- Garmin GPS Marine mount (2 parts-deck mount & GPS mount)
- Three stainless steel bolts (length to suit plastic kayak deck+ 10 mm)
- Three stainless steel washers
- Three stainless steel Nylock nuts
- 2 x Spanners to fit the bold and nut
- Three Weather seals(the secret ingredients = Image (d))
- Rag with clean up fluid(suit the sealant clean up requirements)
Step 2: Placement
- First i put some consideration into the optimum position for the GPS fitting.(so that it was both easy to read and i could reach the keypad with ease from my position in the cockpit)
- This resulted in the "optimum position" being right over the top of the cockpit, and thus the stainless bolts would protrude in the cockpit - away from the legs - but there was always the potential for "snaggyness" in the wet exit's that don't go to plan......
So, i placed the mount
- Drilled the holes
- Tested the bolts
- Removed the mount and layed a ring of sealant around the extreme outside of the three holes
- Replaced the mount with the holes lined up, and put a dolup of sealant into the countersink spots on the mount
- Pushed the bolts through.....Image (C)
Step 3: The Secret Useful Extra...
Then on the inside of the cock pit,;
- First place the stainless steel washer on the bolt
- Then slide a "Weather seal" up the bolt (with the little cup facing down as shown)
- Then the stainless steel Nylock nut
- Tighten the nut up against the weather seal and washer.
- Fold the cap over the bolt end and push until it locks in place.....
- Repeat for all bolts
Hey presto - a nice safe end on the bolts, as seen here in Image (E) - the completed installation
- Then whip back up deck with the right cleaning fluid for your sealant and wipe away the excess.
