hi neil
as long as it stops the worst of it i'll be happy, I'm not a fan of the pram cover either , im going to put a drip around the new deck boards to help the water into the channel,and ive seen that sound proofing but isnt it expensive lol. the sr3 is bolted direct to the hull might try putting rubber matting between the mounts but cant see that making much difference either. Was waiting for a mate who's a welder but cant wait forever need to get on so had a go meself ?.
