Joe, It was probably an installation problem. Look at the inside of shaft zincs and you'll see a small copper colored ball bearing on each half. These bearings are what assure electrical contact with the shaft. If the zincs don't have this bearing, they are cheap imports. Use only Camp zincs through...

Peter, You don't need to haul the boat, but make very sure that your plug is well secured. After pulling the muffler, it's a good idea to also plug the inside as a redundancy. A five inch exhaust port will ship a tremendous amount of water real fast. I've seen three boats sink at dockside. One from ...

Peter, There really is nothing to corrode in a fiberglass muffler, unless it has crush collars already in place and they are really old. Doubtful... Salt water, when evaporated leaves a white mineral deposit, mostly salt crystals, but also calcium deposits from micro organisims. You'll know more onc...

CaptPatrick

Peter, If you find that there is a crack in the neck of the muffler, it probably came from too much tension on the hose clamps and/or excessive vibration. Centek makes stainless steel crush collars that fit into the neck to keep this from happening. If the crack is not major, extending onto the muff...

Ric, It's true that oxides on any metal protect the underlaying metal, at least to a degree... An oxide effectively blocks off further contact with oxygen & thereby stops or drastically reduces further oxidation. Some metals are protected by their oxides better than others. Copper is one of the bett...

Ray, Operating a crash valve, as Randall implied, is only done under extreme situations where the normal bilge pumps won't keep up with the water coming in. Also, the operation requires that you closely monitor the bilge water level and be prepared to shift the valve(s) back to the normal raw water ...

Guys, There's plenty of places to have the hydraulic lines put together, but the problem is finding the brass fittings. Thanks. John, Just about any good hose shop will get the brass fittings if that's what you specify. They may not stock them but can get them, most likely from WW Grainger... Br, P...

Don't ask me how I learned this process I've been sworn to secrecy. As a matter of fact this post does'nt exist. I've known this technique as "The Last Ditch" or "Screw It, I'm Done" Satin finishes certainly are easier to deal with... And, other than some exterior teak trim, a high gloss clear fini...

CaptPatrick

Ernest, Goes back to the original part 1 of my answer above... There's nothing you can do without dealing with the origin of the corrosion first. Silicone, in my estimation, is one of the worst contaminants that you can bring onboard a boat. It falls right in with Starboard. Once silicone has been a...

Frank, Painting over aluminum has always been a tricky set of techniques at best... There are two principles hurdles to over come: 1. Corosion instability of raw aluminum - Aluminum must be passified and immediately chemically treated to block out free oxygen. If oxygen can reach the surface of the ...

Capt Pat, To install the screw out port would mean opening more of the bulkhead than the relief gap now in place. Is there another alternative if "making bigger holes" gets me nervous? Since the midship bilge would then become the principal water trap, is an even larger capacity pump (over 2000gph)...

CaptPatrick

Harry, When the boat is at rest, all bilge water is drawn forward toward the cabin bilge, the lowest spot on the hull being about 6' forward of the engines. I too block off the bilge forward of the engines, but install a 4" screw out Beckson inspection port at the lowest point of the engine/cabin bu...

I used Aero Marine epoxy and did not like it. It was quite viscous and very difficult to wet fiberglass properly. I had to soak it in a warm water bath to drop the vis. After a couple of months, the container of resin phase separated (solids dropped out?) and I had to toss it. -- Marshall Marshall,...

Thanks, JP... This is the delam we discussed several months ago. Inside will only get smoothed off. The overhead, hull sides, and bulkheads get upholstered with off white, foam backed vinyl, like I did on "Buddy Boy".

John, The engine raw water intake is 1 7/8". The through hull should be a 2" with a FULL FLOW 2" ball cock valve. A standard 2" ball valve only has a 1 1/2" actual opening... The Groco strainers should be over sized to fit a 3" port. This over sizing will assure that you have adequite water supply t...

David, Sounds like you may be getting dust or brush particles drawn into the coat. Finish coats can be a real bitch if conditions aren't near perfect... The environment where you are applying the finish has to be totally dust free, including the surface that you're applying to. Mist the whole room w...

No need for a check valve... Seacock & hose straight to the raw water pump. Before hauling out, turn the seacock off, once back in the water, turn it back on. Same with your main engines.

Tom, 3/4" ply is pretty stable stuff & you should have no problem with warping during the epoxy glassing process. The main warp potential can come from shrinkage of the epoxy as it cures.
