Zodiac MK2 GR

I just picked up a Zodiac MK2 Grand Raid last night that I purchased through ebay. The hypalon skin material seems to be in decent shape, and the boat was inflated and holding air when I inspected it before deflating it to fit it into my car. I plan to use this boat for lobster diving and spearfishing with some friends along the California coast.

The boat is missing the floorboards, but it was cheap so I decided to take a chance on being able to make or find some replacement floorboards for it. Does anyone on here have a set they would be interested in selling me or know of somewhere I should start my search? Maybe a boat salvage yard that has a large collection of Zodiacs (not sure if that's even a thing)?

The transom plate says "Model 2355" and the serial number is XDC 42*** M80C. I believe this means the boat is a MK2 Grand Raid manufactured in 1980; can anyone confirm this?

I only have this one picture of it right now that I snapped before work this morning. I plan to inflate it and get it cleaned up a bit tonight to get a better idea of what I'm working with. Once it's cleaned up I will try to post some better pictures.

EDIT: the picture won't upload here, not sure why.

Welcome to RIB.net

Sorry can't help on the floor boards, other than keep an eye on craigslist and ebay. I would recommend setting up an auto search for both.

There is one thread active already in regards to a similar question on an F470.
F470NAVIC P Zodiac

I believe your interpretation of the HIN is correct, your boat is 35 years old.

Have you inspected the transom condition?
Do the IC valves work?

To my knowledge, there are no boat junkyards that handle inflatables, although I do know of one in the midwest that has a lot of parts from junked 260/285/310 size inflatables.

I have only given the boat a quick 5 minute look-over when I picked it up last night (it was dark, so hard to do much inspecting). I did not see any rot or soft spots on the transom and I picked at the glue seams where it meets the fabric; they all seemed solid.

I haven't messed with the valves much yet, and the people that I got it from didn't seem to understand how they worked. They just put the caps on after inflating it to keep the air in the tubes. I did twist one them and it seemed to turn ok, but I didn't have time to test them for functionality before work this morning. Is there a good thread showing how they are supposed to work?

I am not wholly familiar with the valves on your boat, but most all valves will leak a little air until the caps are put on them. The only part that should turn the cap. The inner valve is replaceable and does screw out. They make a special tool, but if you are very careful a pair of needle nose pliers works.

IC valves work like two Styrofoam cups put together. There are two holes towards the bottom of the bottom cup. The inner cup also has two holes. When you twist the flywheel, you twist the inner cup.

You can line up both holes, only hole A, only hole B, or no holes (NAV position). : Westport Marina on Lake Champlain ZODIAC Inflatable IC Valve Parts

The valves should be serviced annually. The flywheels should turn smoothly. However, if a valve is stuck, do not try to unseat it without the IC valve extractor or you may damage the valve assembly (it is a VERY expensive part, around $600 or so). If you are able to remove the valve inner cup without the tool, simply wipe the brass off with a rag of toluene or acetone, apply triple-guard grease to the cup's rotating surface, then reassemble. Be sure to reset the valve's retaining nut to the same height (Easiest way is to count the rotations).

Be sure to clean your valves annually, or sea water may cause corrosion.

Fun fact : The Grand Raid was made famous by Jacque Cousteau.

That is a really helpful diagram. Is the special tool only needed if the inner conical part of the valve is stuck and does not turn?

It looks to me like the triple-guard grease would be applied only to the conical metal mating surfaces. Should I also apply some rubber safe grease to the diaphragm and rubber seal inside the cap? I will have to stop by a boat shop on my way home to pick up a tube of that triple-guard grease.

That's a fun piece of trivia about Jacques Cousteau. I have a picture of his diving saucer set as the background for my computer's login screen.

I think I now know what valves you have?
Zodiac Grand Raid MK3
Zodiac FC470 Project

I think most every diver today and in the past from the Jacques Cousteau era has good memories of him in one form or another Our family rarely missed an episode, along with Wild Kingdom.

Those are definitely them. The FC470 thread has some great info on valve maintenance that's going to be really helpful for me!

Grease should only be applied to the metal mating surfaces.

The rubber components should be washed with a light detergent (Dawn, Simple Green, 409) and reinstalled with nothing added. Silicone type greases may prematurely age the rubber and cause excess softening.

The puller is required if the flywheel does not move or if the flywheel is quite stiff. The old grease tends to vacuum the inner cup in place.

If you cannot remove the cup, DO NOT TRY TO PRY IT OUT. You WILL damage the cup. It is very soft metal. Find a Zodiac service center near you with the tool and pay them to yank it for you. Once it is pulled, simply maintain a regular service interval and you will never require the tool again. (The tool is about $180 or so, so it is not worthwhile for someone to purchase).

If you do not reset the nut to the same height, you will not damage the valve, but you will disable a hidden feature. The IC valves also act as an overpressure valve for that chamber. That's why there's a spring underneath the nut. If the pressure in the tube is enough, it pushes the inner cup up, and air seeps out around the base of the flywheel. If you pull out on the flywheel, it reproduces the same effect.
