Which model of Merry Fisher, sounds like it could be an 805. The anode on the prop protector is a total waste of time if that's the...

30Ma does seem high but the current will depend on the area being protected. i.e. It will take more to protect 2 square mtr. than 1. I...

I believe that marinas are not allowed to mark up teh unit rate, but they can add a 'service' or 'supply' charge. Businesses usually pay...

I was under the impression that no mark-up is allowed at marinas also. Does the marina tariff show what they pay ...

My own boat is 10ma. We also disconnected both batteries on friends boat and there was no change, anode current remained consistently...

VicS, your comment about 30ma draw resulting in the loss of 0.3kg of anode was something I hadn't thought of. I found some other...

I agree with that . I keep my boat afloat all year although not an a swing mooring. have solar panels keeping my domestic and engine...

Instead of running the engine once a month to charge the batteries, consider installing a modest solar panel, with suitable regulator...

It is in a marina but Shore Power is never left connected when boat left unattended.

But post #5 says "the boat is never left with shorepower attached"

Apologies, I missed some very pertinent info, the boat is never left with shorepower attached and batteries are always isolated before...

This sounds very odd. What sort of boat is it? If it is GRP then the need for anodes and any form of "bonding circuit" is very limited...

The loss of anode and retaining bolt would lead me to suspect an electrical fault causing electrolysis, especially if this occurred in a...
