Hey everyone, I have a 1997 336. It has a 1" shaft and I put one zinc on it. Should I put more than one? I'm replacing it every two months because it is eroding so quickly in the marina. I have briefly spoke to a few people that suggest a galvanic isolator should be installed. I currently do...

Hi everyone, has anyone had all exterior lighting issues on their Cat? I recently purchased my first Catalina - 30 1978 she's had a few lighting issues. Anchor light is out since purchase Stern light recently burned the casing and went out. Port and starboard lights worked for a few days then...

I'm replacing the ancient electrical panel in my 1993 Hunter 23.5. When I pulled the old one out, I found the expected mess and started tracing wires. The pictures attached are of two connectors (electrical I believe since wires run to them under the floor in the cabin) at the rear of the...

Hi all! First post on here. I've been lurking for a few months and learned plenty and now I would like your opinions on something I have on my mind. First my back story: There is shore power at my marina, but not at my slip. We don't consume much power - no fridge: we have an ice box, and...

Well I should have seen it coming. The main sheet caught on the positive cable exiting my flexible solar panel and ripped the junction box clean off. Image by Genesis V posted Jul 4, 2016 at 9:12 PM Is there anyway to repair this? It a $400 replacement. Would be nice to solder on extension...

A while back I stumbled on someone's video or likely picture story on how they added pneumatic rams to assist opening up compartment cover, added LEDs, built battery storage compartment and cleaned up the wiring adding various devices. If you know where to find, I'd appreciate the heads up...
