No the weather was ****. Will do it this weekend, as I really need to put the screws on Raymarine for a fix.

Re: Airmar / Raymarine DST800 Transducer Issue

I was out for a sail yesterday so took a quick video of the water flow when changing the balancing plug for the transducer.

You can see clearly (through the water flow) that there is no flap or anything slowing the flow of water.

I expect you were using one hand for the video. Ignoring that you are taking too long.

Have the plug going in ready to go in one hand with the arrow aligned. Use the other hand to unscrew the plug in place. With one plug in each hand you should be able to switch in two or three seconds. Fast lets in much less water than enters in 15 seconds.

sail fast and eat well, dave

Yes normally it takes me significantly less time. I was however wanting to show the water flow.

Re: Airmar / Raymarine DST800 Transducer Issue

From the amount of water coming in in that video, it does seem to me that you've lost the flapper.

For completeness, here's a link to the installation manual for this beastie - I assume you guys are following it to the letter? http://www.jamestowndistributors.com...20_install.pdf

Of particular importance here:
1. On the blanking plug, inspect the O-rings (replace if necessary) and lubricate them with the silicone lubricant supplied or petroleum jelly (Vaseline®)
I found out the hard way with my DST transducer that if the plug wasn't properly lubricated when you pushed it in the first time, due to the extremely close tolerances, pulling it out pulled the flapper out also.. but after doing that once and learning from my mistakes, I've been smearing Vaseline on the plug every couple of times I use it, in accordance with the instructions. I really haven't had a problem since.

Re: Airmar / Raymarine DST800 Transducer Issue

It was installed according to the instructions by a Raymarine agent so I can only assume they did it correctly.

There is heaps of lubricant on the transducer and the blanking plug so I doubt it's a lack of lubricant causing the issue.

I know from Raymarine that Airmar had some issues and altered the design a couple of years ago, below is what Raymarine sent me prior to us having the new one installed;

"Regarding the DST800 snap ring, the the ring design was revised as a result of NCR712, reducing the ring gap from 0.56 to 0.112112 in on Airmar ECO 09E0197 with an effectivity date of 02/18/2010. Airmar has implemented the change on all affected products and has purged all of the "old" snap ring stock. If you can provide the serial number(s) or date code of the affected units I will confirm the mfg date and whether these units were assembled with the old or new snap ring version.

As you may recall, the risk of the original valve becoming dislodged requires the ring to be positioned with the gap positioned directly over the valve hinge. Assembly instructions include the orientation of the snap ring with ring gap 180 deg from the valve hinge. An incorrectly positioned ring could occur during assembly, or during post-delivery handling. The ring can be rotated by hand from the "as assembled" orientation (180 deg from the valve hinge) during installation or subsequent handling. Please note, that with the snap ring gap located over the valve hinge (incorrect placement or subsequent manual rotation), the valve body remains securely retained within the housing, but includes a higher risk of failure due to the size of the snap ring gap and valve hinge.

Re: Airmar / Raymarine DST800 Transducer Issue

I pulled my DST800 transducer today. Far less water ingress than seen in your video. I was surprised to see how well the flapper worked. Minor geyser 2-3 inches high.
