Roger Sir!

Are Bob's machine shop dual engine jack plate OK for my RIB?
Bob's Machine Shop - Double Jac

The dual plate looks a bit simpler and it fits on my narrow extension bracket...

Were there some PMs between you too that went from engines too low to jack plates? Seems like a drastic solution to engines that are an inch or two too low. I know Ryan uses them as he operates in shallow water and other conditions that most of us would avoid. But if these engines are too low wouldn't just moving them a few holes be a valid solutions? I know new holes were drilled but there isn't that much room to mis-drill holes on the bracket. Are the rest of us missing something here?

Jason,

I will try to explain.

I will be operating from the estern coast of Phuket and there are plenty of shallow water around Phuket and Krabi. For example, the Marina I am going to be based at for a while, has a 3 miles channel with the depth of about 1 meter, and it goes through a very shallow bay. We have 3m tides and I have seen some standing waves in that bay when it was windy.

I have been thinking about adding the jack plates for a year or two. A friend has a RIB (a bit longer than my Zodiac) and he has Bob's Machine Shop Hydraulic plates with his Yamahas and he can dial in a fuel saving mode or improve the general balance of his boat with his plates. Another local diving RIB has jackplates and the owner installed them to be able to lift his engines from the water and avoid the galvanic corrosion.

I had the boat rebuild at a Pattaya boatyard and I am very happy that I was able to use them, they are very good. But the boat is in Phuket, on the other side of Thailand and, to be honest, I want to be independent from the yard in the future and use somewhat cheaper local labor. My poor English is better than my Thai and there are a lot of complications and misunderstanding between us. And I think that the price of the Jack Plates, even hydraulic ones, will be comparable with the price of several liftings and sea tests and fuel costs and moving the boat around if I use the yard again.

Yevgeny

another big+

keeping the trim units out of the water will greatly extend their life while at mooring

I'd say so! Anybody else here that speaks English, Russian, and Thai raise your hand. I'm American so unfortunately we only speak one language, what that is called is debatable too :-)

Yevgeny, thanks for the explanation. sounds like you have some extreme conditions there I don't and am not familiar with running a boat in. I'm always concerned that there is something I should have done with my boat and missed.

Jason

Wow!

Now that is a full extension. is that 48" looks like you are extending your tubes, or are you building new tubes?
