Mounting a bow mountedl trolling motor

Got tired of working on the foot control on my old motorguide that came with my tracker so I am now mounting a new to me Minn Kota Edge. The old motor was held on by the blind rubber 1/4" isolators that really haven't given trouble in 20 some odd years of use. I know a lot of folks don't like the rubber isolators and use snap toggles in the blind holes. I would like to use the toggles but am worried that a tight connection to the boat would transmit noise through the hull. any pros/cons here?

take an old truck floor mat and cut it to the shape of mounting plate and put between deck and trolling motor

I used two rubber sheets about 1/2 inch ,one is screwed to the boat , with bolts facing up through it to bolt to the upper sheet which is bolted to the trolling motor. No direct contact from trolling motor to boat . This works for me.

ended up getting the toggles and have a floor mat. I think it'll be fine.
