Hello... trying to help out someone who recently purchased a Roughwater 33 and likely needs some zincs replaced.
.
Trying to find the info before having to dive to find out.
.
So I'm just looking for the zinc(s) location on the hull/rudder/shaft, and what type of zincs are used.
Been trying to look at pictures on the internet... kinda hard to tell if there's space to put a zinc on the prop shaft or not. Saw one boat that had holes in the hull... bolt-on zincs? Didn't see any images online that showed zincx bolted to the rudder.
Best I can tell so far... the shaft might be 1.5inch diameter? But I'm not going with that until I hear something more definitive.
I cannot get below decks for the time being to measure the shaft from inside... even if it's accessible enough to do so.
.
Thanks
