Anodes & GRP

[Guest]

My boat is GRP, with inboard diesel (indirect cooling) and alloy/stainless jet drive - it will be kept in a seawater marina berth - any recommendations for anode protection (the jetdrive unit already has 6 zinc anodes fitted.

Don't use shorepower (if your engine / drive is connected to earth).

Add some more anodes?

Don't use shorepower, as Andy says - unless you fit galvanic isolator. These cost somewhere over £100 and are exactly for your situation.
