Continuing with the rubberised theme started by Matthew (beach rollers), has anyone tried isolating their outboard clamps with anti-vibration pads? The idea being to reduce the amount of vibration and noise transmitted by the outboard through the transom mount to the rest of the hull. The pads would need to be mounted on both sides of the transom clamp and, because the upper part of the clamp rests on the transom, probably over the top as well.
In an ideal world, pads fashioned from Linatex natural rubber sheet might be best but unless you're in the extractive industries or tend to horses professionally, a small amount is difficult (or even impossible) to come by. Has anyone tried anything else?
I was complaining about my Torqeedo 1003's noisy whine on another forum the other day. Someone suggested that part of the problem (other than the issue with the over-large motor mentioned elsewhere) could be resonance caused by the way the motor is mounted in the boat. Is it possible that the BR outboard well acts as a sort of loudspeaker? If so, isolating the motor from the rest of the boat might help. Likewise filling the outboard well with ping pong balls (only kidding). The Torqeedo doesn't vibrate much but my Mariner 6hp definitely does.
