Tunnel size on a 43ft Bayliner?

[boatworkfl]

Does anyone know what diameter the aft end of the tunnel on a 43 ft. Bayliner is? Measured at just above the trim tabs, or what the circular diameter is?

Hmm, never thought of measuring tunnels on my 4388, my tunnels seem to raise up into the aft deck floor 6 to 8 inches? Could measure if you like.

Please, yes I would like to know that measurement.
From just above the trim tabs recess width, and the height to the top not including any recess for the strut. I photo would help also.

I couldn't find any explanation of "tunnels." Can someone
explain what they are to me?

This pic top of tunnel looking down into aft deck starboard transom wall. It measured 24 inches across from the stringer to the starboard deck. Probably wont help you much. Boat is in the water, I'm good friends with the diver and we just changed zinks last week. He is planning on cleaning props soon so Ill have him measure after Thanksgiving. Had to get over to tighten lines, blowing 50 tonight, again... In Seattle for a week over Thanksgiving then back over.....Happy Turkey!

It looks like your rudders are aft of the transom, if so tunnels will not work, they must be in the same location as the 38xx series since the tunnels bolt directly to the transom.

prop pockets, I do not think all years had them.
A member was asking me if my fiberglass prop tunnels would fit their 43 ft Bayliner.
