My maramu seems to have non marine ball valves fitted as seacocks
Whilst they look new I assume I should replace these with marelon or something equivalent
At the risk of asking a daft question . . These Amel Thru hulls are new to me. Is there a threaded section glassed into the through hull? If so is this metal or a plastic?
It'd be a great help to know before I attempt something stupid !
Many thanks in advance
