I have noticed a very slight leak on my DataMarine transducer ( I have a large fairing block on outside) . Not sure how this particular transducer disassembles. Any insight would be would appreciated.

Re: DataMarine transducer disassembly
Is this speed or depth?
Your taking it apart on the hill?
To replace or re-bed and re-install?
Looks like a speed sender.

Sorry, yes this is the speed log. Will investigate further as it's very minor leak but I'm in the water .

Re: DataMarine transducer disassembly
You pull the pin and it pulls out from inside. Don't do it in the water. It seals with a couple of o-rings. They probably need to be replaced.

Re: DataMarine transducer disassembly
Thanks. Is the plug a screw on or similar push in? I'm not seeing one in my inventory. I'll have to order.
Is this fitting something you've serviced over the years?MV "Mystery"

Re: DataMarine transducer disassembly
There is a pin that goes thru the neck above that butterfly nut. It holds the internal round chunk in place that includes the speed paddle wheel, mag pick up and signal cable. Around 1 1/4 inch in diameter, 2 inches long.
In the picture below, this safety ring should be on one end of this pin to hold it in place, not to pull on.
The other end of the pin looks like a nail head.
The whole chunk should then pull straight up if it was properly installed,, with grease.
There is no internal valve to stop green water from flowing in.
The outside threaded tube is held in place like a normal thru hull with that butterfly nut and some caulk.
Mine has no guide when re-installing. Ensure the paddle wheel is facing forward, push straight in, rotate a lil till the pin can be re-inserted.
On this chunk (cartridge?) in an O ring (or two?). This would be normal suspect #1.
Thru hull caulk is suspect #2. Cracked plastic thru hull is suspect #3.
This is old plastic (Nylon, Polycarbonate, PVC or like?).
Mine is in good shape but 46 years old.
In the water would not be a good first time service of this gizmo.Last edited by Captain Ralph; Today at 04:11 AM.

Yes, I am chicken.
I'm not going to tell anybody it's O K to open a hole up on the bottom of their boat.
Then use rags if there is a problem.
