73 Cal T/4

Hello All,

I have just this morning joined this merry band. I did so because I have a question that I cannot answer, and it seems likely that I'll confront other conundrums later. Here is my query: does my (recently acquired) T/4 have a cored hull or is it solid FG? - the reason: I want to install a new in-hull transducer and they cannot shoot through cored hulls.

Cheers,

Sumayloly

Re: 73 Cal T/4

Do some searches on Google for thru hull transducer installation. I believe I have read where you can take the transducer and a zip lock bag of water or oil, place the transducer on the bag making sure there is no air bubbles. Move it around to different locations to see if you can get good readings.
Even cored hulls sometimes have solid areas where stress is expected or strength is needed. If all works well, make a more permanent installation.

Re: 73 Cal T/4

I don't recall the Cal folks doing cored hulls in general. However, you should be able to determine the construction by simply inspecting the area where the hull meets the deck. Cored hulls will have a transition area where the coring ends and the hull tapers down in thickness for the flange. It is pretty obvious in most cases!

Nonetheless, doing the "waterbag" test is a good idea, for it will help you find the best spot for the mounting.
