Raymarine depth sounder

[Boathook]

My new to me boat has the through hull depth sounder right towards the stern.

I've got a spare P316 dual frequency depth transducer. It is meant for through hull installation, but I'm wondering whether I can mount it inside the hull in a more suitable location in a tube filled with antifreeze. I will mount it vertical, etc so the tube will need some shaping before bonding in place.

Any reason why I can't use it "in hull" ?

Providing it's not a metal or cored hull, no reason at all.

But, what's wrong with the current location ? If it works, there is no reason to worry about it being towards the stern.

If you do fit the P316 there is no need for a tube and antifreeze. Clean the surface where you want to fit it, make a dam with some plasticine. blue tack etc. Pour some epoxy into the dam, enough to level out the hull deadrise. Let it set. Add a small amount of epoxy and push the transducer into it with a twisting motion to eliminate air bubbles. Job done.

Someone will be along shortly to tell you to use silicone, CT1 etc. Airmar explicitly say not to do that, they soak up some of the returns and make the result inaccurate.

Well my airmar transducer is bonded to the inside hull surface with Stixall sealant. Works fine.
Just clean the surface with Acetone, one big splodge so no air bubbles and push it on.
The advantage is that the transducer can be cut off with a knife if needed.

I did say you'd be along shortly

I'm possibly going to mount it in a tube filled with antifreeze. This keeps my options open if I want to move it easily.
