My First RIB Zodiac 733

I've been trying to get a 733 from GSA for a several years but its never worked out. I live near Lake Michigan so they're never anywhere local. Recently, one popped up at a sheriff auction about four hours from my house, it was used as the Sheriff rescue boat but they had another boat they preferred to use, so the Zodiac wasn't getting much use so they put it up for auction. The boat is a 1998, with twin 2006 135 Optis, after a couple smartcrap alarms for a dirty strainer and water in the filter she runs perfect, only 140 hours apiece when I picked her up! I thought I was going to have to do something with the tubes because they looked so faded and terrible but they cleaned up unbelievably well, couldn't believe it! This boat gets so much attention, most people think I'm the coast guard when I drive by .
The pics are right side up on my computer not sure why they're turning sideways when I upload?

The first picture above was after I cleaned the tubes on the inside only, I thought the tubes were faded, but it was oxidation, and it came off fairly easily; after a few hours you wouldn't believe they were the same tubes, I was very surprised!

They gave me an extra set of tubes with the boat too, I think they might be the original tubes that went to the boat but I don't know for sure. They are the same year as the boat, but I think they might be urethane, is that possible? They don't have overpressure valves like the ones on the boat now, and they're certainly not similar material, not sure if they're worth anything, if I should keep them for a backup, get them refurbed or what? They've been holding air for two weeks in my shop. I made a video of my homemade electric air pump, airing them up for a test. The boat came with a built in inverter so I figured a cheap 120v turbine might work well, it pumps the tubes to the lower side of acceptable, but does so quite fast. Its really easy when I get to the boat now to top off the pressure from the sun operating the OPVs.

Quite a luxury to have an extra set of tubes!

I have often been shocked at how well tubes clean up after some elbow grease. You are quite luck to have an extra set laying around.

I also like your DIY pump, seems to really inflate that tube set quickly.

Thanks Bodge! I tried it the other morning on my little 15 foot zodiac and it aired it up completely much faster then using my air compressor. Cost 30$, a hose clamp, and 5 min on the lathe.

You have a nice Rib.

If money or storage is not a problem for you, then I strongly advise holding on to the spare tubes. One bad oops on the boat could ruin the tubes. Hopefully that will never happen but if it did then you will have a cheap solution to get back on the water quickly. I recommend cleaning them up and put the spare tubes away properly so they'll be ready to use when needed. A new replacement set could be very expensive; $15K +. I would also think it would add some good resale value to your boat if you decide to sell it at a later date.

There are 12v air pumps to fill tubes that can set set to shut off at the requested PSI's; it's made by Scoprega Bravo. Keep an eye out for them on Ebay. They are not cheap but are a godsend and highly recommended. Their made in Italy. The older ones come in a larger soft case boxed shaped. These pumps automatically shut off the air at the selected psi’s/bars so your tubes don't get damaged from over pressure. I believe most ribs are 2-3 psi’s (.2 bar max). Just add a 12v socket on your center console and your good to go. No more foot pumping and your tubes will be set to the proper PSI's every time even when not being attended. Not sure if your invertor will be able to handle the loads of a wet/dry pump.

Here's an example of one currently for sale:

Another recommendation, You may want to remove the rear roll bar and engine guard. They are quite heavy and the equivalent of having a heavy person (maybe much more) sitting on the stern. You'll probably immediately feel the boat perform better and will feel more balanced without it. They're not needed for recreational use. They're also easy to remove and re-install. I would not doubt it also has quite a bit of windage drag slowing the boat down at speed and will effect fuel consumption. Just a recommendation.

You have a T-top so you can easily install any lights or electronics on that, there is even a mounting platform for electronics on the T-top.

The trailer you have is aluminum which looks in excellent condition. You couldn't ask for a better one.

Enjoy your new boat, it looks very nice. Cheers

Nice find! You lucked out with the extra set of tubes. We need some action shots of your rib in the water!
