I decided last month it was time to upgrade my depth sounder to a fishfinder...
As the old Lowrance sounder used 192kHz I had to replace the transducer to use a modern 50/200kHz fishfinder anyway so I bought a 60mm titled element through-hull transducer and drilled out the hole of the original 50mm plastic one.
All was going perfectly to plan until I noticed (after I'd got everything covered with sealant) that the hull around the hole doesn't seem to be of uniform thickness - it seems thinner away from the keel line... so when I tighten the nut on the 'ducer it contacts at one side only, not all around. Not great for a watertight seal!! :smt017
I'm sure I've drilled the hole at right angles as the transducer is flush on the outside of the hull. And the old plastic transducer is actually bent where its been bolted down.
Anyway - I've just spent the whole evening cleaning myself and the 'ducer of sealant and trying to work out why and how...
Anyone else spotted this? - How did you get round it?
Cheers,
Nigel.
