  1. What's a J-Bolt?

    E32-3 What's a J-Bolt?

    Ultimately, a lot can transpire during ownership, a ton of value added, or taken away and ultimately something is sold at a price where the value/cost proposition makes sense for both parties. Was this boat a good deal? Not sure… Maybe this blog is a way for me to justify and convince myself I...

    Stainless Bolts, Aluminum pedestal Base (dissimilar metals)

    Hi all, please see attached photo. Curious on ideas of how to prevent corrosion due to dissimilar metals. Dielectric grease is looking to be a good prospect at this point. Other ideas?

    Boom corrosion

    Has anyone seen corrosion like this before? This taken from my boom. It was suggested to sand this off, but I’m thinking to will scratch the metal. Thoughts?

    Strange corrosion problem

    Hi, I would appreciate any insights or help on a puzzling corrosion problem on my E30+ Yacht Specialties steering pedestal. The part of the pedestal that holds my speed/depth instruments sits on two 1" stainless steel tubes (sorry, don't know how to post a pic). The part in question is made...

    SS corrosion ?

    Looking through the pictures from last weekend I found some that show corrosion in the steering linkage. It is a major effort to get in there (I held the camera at arm's length and shot in the blind) so I don't want to dive in there right away unless it is necessary. It looks to me like...

    Aluminum Corrosion

    When refitting the mast on my 28 I noticed that the tapped holes that hold the top pulley assembly for the jib and forestay in place were lacking in strength. So I used two plates of drilled and tapped aluminum behind the mast (on the inside) to reinforce the attachment. In my haste I forgot to...

    crevice corrosion ... be careful !

    Yesterday I removed the pretty decorative covers inside from my upper chain plates. I had pulled up all the chain plate covers on deck last week and scraped out the old sealant and dried the area some with a heat gun, before resealing (for now). It's my attempts at stopping any new moisture...

    How bad is it? (Part 2: Boom Corrosion)

    Soliciting ideas on how this might be dealt with and what kind of cost I might be looking at if a yard does the work. This is on an E30+. This is something I might be able to do myself. It's a Kenyon boom and I believe Rig Rite may be able to supply spare parts; if any aluminum welding is...

    Rubrail corrosion

    The aluminum extrusion on the E38 we tried to see yesterday looked like it had been attacked by aluminum termites :-) It probably wasn't as bad as it looks but I wonder if we should expect the damage to be more than cosmetic ? -Sven

    E39B Chainplate Corrosion

    I went to re-seal the aluminum chainplate tabs that extend up through the deck from the glassed-in knees. There has been very slight leakage around the chainplate tabs in the past year, but they looked very solid below and above the deck. Unfortunately, when I got under the old seals, I found...

    E29 - hole in mast from corrosion

    I saw a early 70's boat last weekend with corrosion on the mast from where the winches had been. All 6 of the 1/4" bolt holes were corroded as was the whole area. This is the case on both port and strbd sides of the spar. But one of the holes has corroded to the size of a penny and is jagged...

    Ericson 36C 'Blue Jeans' Mast Corrosion

    The mast from 'Blue Jeans' has corrosion on the bottom. I am considering cutting about 1/4" to 3/8" off to remove it completely. Is this a reasonable fix? What will that do to the mast rigging? Bob McKee 'Blue Jeans" Seattle, WA

    Cutlass strut corrosion

    Recently had my 1971 E29 hauled for bottom paint. Cutlass bearing was worn, so decided to replace it. Removed the cutlass strut, and found that the stainless securing bolts were badly damaged by electrolysis. On removing the cutlass bearing, the bronze strut itself cracked. The yard where...

    A great corrosion resistant coating

    Hi All, Thought some of you might want to hear about a great product for preventing corrosion on aluminum (and probably lots of other things). It's called Nyalic & was developed by NASA for use in extreme conditions. It is a clear liquid which you paint on and it dries slightly glossy but...

    Heat Exchanger Corrosion

    My 1987 Universal MK 12 engine runs fine, and the heat exchanger appears to be doing its job. Recently, however, I decided to change the zinc in the exchanger. I do not know when it was last changed. When I took it out, there was no zinc left, only the threaded part. When I tried to replace...

    Propeller Shaft Assembly Corrosion

    I have owned my E28 for about two years and sail in the San Diego area. Just recently I noticed what appears to be galvanic corrosion forming on the shaft packing area just inside the hull. I do not see any evidence of zincs anywhere in the area, and nothing in the owner's manual mentions...

    Motorbase Corrosion

    Looking for information from experienced owner (mechanic) about repair of corroded motor base supports. During a recent inspection before layup I became alarmed about the corrosion on the angle support of my '68 Ericson 30. The piece in question appears to be one of four steel angles running...
