Permanent Wet Transducer Installation

[dsafety]

PescadorePete,

The sonar transponder is directional. If you have the transponder pointing to the stern, your fish finder will show you things you have already passed so what shows up on your screen as you move forward would be what you would have seen if you moved backward had the transducer been aligned correctly.

If all you are using your FF for is to tell the depth of the water, this is probably not a big deal but if you are using it to actually locate fish or bait, you could be making decisions based on reading the data incorrectly.

Wahoo,

I don't think a thicker rubber cap is any big deal. It may make it harder to spread open the hole to get your plug through the rubber but if that is the case, just make the X cuts longer. You will be sealing these cuts with goop later anyway.

If you simply cannot spread the rubber wide enough, just drill a suitable sized hole in the rubber. Thread your plug through the hole and attach the transducer. Tape one side of the cap and fill the former hole with goop making sure you have some overlap on cap. When the goop has cured, go to the other side of the cap and spread a bit more goop there so the "plug you just made will not pop out.

The thicker rubber might actually make it easier to mount the transducer with screws since there will be more material for the screws to grab on to.

When you have completed your installation please post a photo for everyone to see.
