Alan, I believe you have hit the nail on the head. It’s all about the resistance at the joint to the bolt. A wide flat strap provides the maximum surface contact area between the strap and the bolt.

Thanks Annsofie, That sounds like a good idea. Cheers Alan Elyse SM437

Karen, Great summary! -- CW Bill Rouse

The fact that it is only milliamps makes the conductivity very important. Even a slightly bad connection at the keel bolt will make the keel rust. Best to use 3mm flat copper bar to make the best

When Bill recently did the timing belt on our engine, he used a good belt tension gauge, and a dial indicator to re-time the injection pump. He also replaced the tension and idler pulleys. They

Copper wire should work. I still prefer copper bar. Best, CW Bill Rouse Amel Yacht Owners School - www.AmelYachtOwnersSchool.com 720 Winnie St Galveston Island, TX 77550 +1(832) 380-4970

Hi Mark, No, unfortunately I did not get a manual for the earlier SM’s — as you say it would be very handy to have. The search continues! Best, Mark S/V It’s Good SM #105

I am sitting south of Barcelona. One group member put me onto a German supplier, a former AMEL owner is trying to source it out of Britain and I have been told AMEL does still have them. Glad I joined

Paul, I painted my main mast with alwgrip ten yrs. and it was a perfect match. I just sanded it with 320 grit and then roll and tipped it , I did not prime it other than a few spots where I had

I have Furuno Tz as the main system using C map charts. I do all routing on a laptop Interfaced with the Furuno and running the same charts. I’ve come to appreciate Navionics app and charts on my

Hi Bill what’s your thoughts on using copper wire, instead of the strap. Will this provide enough electrical conductivity? Regards Ross SV INTREPID KIWI SM2K 356 Currently Croatia Sent from Yahoo

Thanks for the input All it looks like there are a lot of options. i like open cpn but it will not work with IOS think i will invest in Aqua maps for now

This is the one and only time that I will say that the Amel OEM part is not the best part. Amel uses a thin copper foil for the bonding strap inside the gray water bilge. In terms of electrical

This bilge bonding strap conducts micro volts. Stainless steel is much, much less conductive than copper. If I remember correctly, stainless steel has about 2-5% the conductivity of copper.

That is awesome Robin. I will be onto it in the morning. All the best, Randall

I think it was around 90 euros — just tell them the bonding strap for the bilge of a SM — they will know what it is. It was easy to get to the cables but was a problem to loosen the nut on the

Thanks Robin, Did you have an part order # for the strap. I'm in Spain and you would think copper is gold down here. I just cant find a supplier. I am looking at doing the mast step as well. Eight

Thought of that, if that is all I can get it will be a last resort. Copper pipe is a blend of metal. I believe hat Bill R. is not a fan either. Hoping to find a good quality copper. Thanks Keith take
