Transducer Swap

[Uniscoot]

Hi All-
Someone mentioned the technical wizards on C30 specs are here.
I have a 1983 C30 Mark I.

I am going to replace my Raytheon M 78923 transducer with an Airmar B744V-6G transducer and need to know the hull deadrise just forward of the keel. Someone mentioned it is in the 20 degree range, I need confirmation before spending $.

Any help you can provide is appreciated-


Thanks , Scott
