Corniche anodes

Post by ColinK » Sat Apr 16, 2016 7:43 am

Hello all,
Well Summer is on its way and looking forward to the season. Daughter has GCSE's. so tense time but I understand once she takes her last exam and has the traditional "prom" night then we are free.
I am planning a lift quite late and this will be my first with her. Wonder if anyone knows how many and what size anodes my Corniche may have (shaft driven) I have found two points in the Lazarette where lots of black wires go to and the bolts there are 9" apart.

Cheers. Colin.

Colin

A couple of 4kg bar anodes. Measure the precise centres between the bolts 200mm (~8") is very common.

Check the resistance from props and P brackets to the anodes is below 1 ohm.

A per above plus mine has a disc anode on each trim tab

Don't forget the engine anodes which can be changed anytime

one in each heat exchanger

look for a square head plug, the anode screws onto the plug

dependant on engine year you could also have same fitted to intercooler and/or gearbox oil cooler

Wow thanks chaps I know my next job.

I am confused by the size of the external annodes. Remeasured the bolt centres in the lazarette and they are def 9" centres and all the ones that I can find are 8". Any ideas?

Cheers, Col.

Hi Colin

Usually the hull anodes have slot rather than holes to allow some slight tolerance when fitting

On mine I found the readily available bar anodes, and relevant backing pad fitted just fine

Use one of the original mounts and drill a new one either fwd or aft to suit.

Engine assuming VP TAMD Oil cooler; Gearbox oil cooler; After cooler

Do not forget to do these as new cooler are way over priced and essential

Howdee chaps,
Hope everyone is having a good Summer so far? We are being lifted out on 14th for a week so fingers crossed I have got to decide on what type of antifoul and chech the dreaded anodes.
I contacted a supplier of anodes today and asked him about the odd spacing on mine (9"). He said that yes he stocks them but they are huge much bigger than you would normally put on a boat my size. Now I guess that I have my fingers crossed as the chap that I bought the boat off said that he had just changed them so about 16 months ago although do bigger anodes last longer?

All the best, Colin.

Hello chaps,
Always try and report back so now I have had my lift out can advise on my anodes

The 9" centres on my Corniche are original by the looks of it and are 12kg anodes rather than the 8kg 8" centre ones according to the anode maker.

In the end they were only a third worn so ok for a nother year. The 2kg ones on my trim tabs were gone so just managed to get 4kg lumps to fit.

Happy Summer. Col.

Hi

The anodes on my Corniche are 7kg 9"(227mm)centres and use 16mm bolts, anodes direct do a suitable model, normally get 2-3 years out of them

Hi Colin

Just come back down the Thames, good weather most of the time which makes a change.

This is a link to anodes direct, delivery is quite reasonable
