Catalina 30 thru-hull size

[Fstbttms]

Anybody know the size of the knotmeter and depth sounder transducer thru-hulls on a mid-80s Catalina 30? Thanks.

Are they Datamarine Instruments? Do an Internet search for them and you will get a phone number and email address for service. All I have ever seen on non-upgraded Catalina 30's are these. If they are Datamarine, they will give you the best answer.

Wouldn't that depend more on the instrument provider than the boat design itself???

I'd check the literature of the instrument manufacturer.

Yes, read of the manufacturer, and give them a wee call.
