Hello, I need to service the bow thruster on my 46' 1987 Maramu. Can anyone provide me a list of the normal parts to order with part numbers if possible? Also, my thruster has not been

That makes sense, Bill. Guess I was thinking of sea water on furler, deck, hull all interconnecting as if submerged. So the furling motor is not bonded to the zincs? What about the bow thruster? If

Kent, Bonding would have no effect on corrosion here. The zinc that is attached to the bonding system has to be in the same “body of water” as the metals it is protecting. In this case the

FOR SALE 1989 Amel Maramu hull # 261 Sorry for the advertisement but this is the best place to get the word out... This boat is from the last lot of the <300 Maramu 48's produced. Very well

I don't know if the furler on Kristy is connected. Sure seems like it should be...exposed to sea water, dissimilar metals. Wonder why it wouldn't be? Anybody else know if their furler is

Hello Kent, None of the rigging on my SM is attached to the bonding system..... Cheers Alan Elyse SM437

We have had a similar thing happen, but the plate is not totally destroyed. We were sailing with 2 reefs and then suddenly the jib unfurled itself. Tried with the motor and it was turning but the jib

Yes, Pat, salinity, temperature, and water flow can all affect the reading, although I don't remember exactly what happens under those circumstances. Kent

Kent ,We put a large , massive zinc over the side , connected it to gen set and the number only went from-804 to -825. Would fresh water , opposed to salt water change the numbers expected , the

Hi Bill, I had this plate corrode on my Super Maramu in 2011. One day I noticed the corrosion and kept my eye in it for a couple of months as it progressed fairly quickly. I could not detect an

Pat, if the hull potential is different from the drive than from the engine and everything else, it isn't connected well to the rest of the bonding system. Normally you would see a better reading at

Kristy, Why do you think the drive connection has failed , if it shows Like -1000mv , I may have left off the - in my email , is that why? I guess the engine can be bonded to the zincs without being

Just shooting from the hip here Bill, I've not heard of a failure like that before. Glad you were able to get it furled manually...did you have the manual furler set up already? Certainly corrosion

In the SM jib furler, there is an aluminum plate that transfers the torque from the motor to the foil via the release pin. It has one large hole in it that accepts the release pin, and smaller holes

The engine should be bonded separately from the CDrive. Kent

Hi Pat. It sounds like your drive connection to the bonding system has failed. Do you have a prop zinc? On Kristy the connection to the bonding system is at one of the bolts on the housing at the

How is the Cdrive & engine protected , if it not connected to the bonding system. With the silver anode the electrician had a reading over 1000 mv at the C-Drive, and at the strap 804. With the

I don't have the same converter, but I have had other converters fail due to a blown fuse. I suspect yours has a fuse as well. If the rocker switch wasn't accidentally turned off (the timing

Hi Enio, understood. On KALI MERA the connection from AC-ground to the bonding was original (at least it seems so and would make sense), do not know how it is on the other Santorins, but I think it
