I installed mine on the R/H side. I used 3m 5200 sealant on the screws. I put a SS pitot cover over the thru hole where cable goes into hull used plumbers putty on the outside only to stop the 5200 from running out & making a mess from the inside. I cut out a piece of poplar wood to fit into the cup holder on the dash to mount the display. I used 2 electric tape holders to act as a base/spacer in the cup holder. The wood is a snug fit but i didn't want it to work it's way down from the pounding of the wakes. Measure twice drill once! I put tape over the gel coat anytime i drill, stops cracking of gel coat. Some say to drill in reverse. I haven't had a problem doing the tape thing. I also installed attwood flush mount rod holders on the gunwhale. High speed no doesn't work false readings.
