Deadening that dreaded donkey

Postby Simon Head » Tue Mar 31, 2009 8:13 pm

Has anyone managed to develop a system to quieten down the donkey?

I have a 5hp mariner 4 stroke which is noisey in the cabin when being used- has anyone devised a way to sound proof this?

I am thinking of resolving this once and for all by using vibration mounts under the motor mounting bracket and rubber beneath the outboard clamps - has anyone already done it?

Hello Simon

I like the idea of the anti vibration mountings. I have done a quick search on Google and found that RS Components sell a comprehensive range of cylindrical rubber mounts with a choice of threaded studs at each end. This I think would be a neat solution, although I do not know how effective it would be, until someone tries it.

I remember that someone has used rubber for this purpose because it got mentioned during posts (on Yahoo) last October (I think) when I was having on line discussions re the best outboard for a CC19. I think there was even photos of the arrangement.

Hope this helps

Hello again Simon

I have checked on Yahoo, it was Bram Marck
CC59 "Kerina" who has used rubber to reduce vibration.

I see Bram is now a member of this group so he may be able to give some advice.
