B275 or B265 thru-hull transducer on Express 330

[BRO-CAL]

I’m looking to install a B275LHW thru-hull transducer on an Express 330 but it is a beast of a transducer and space in the aft bilge with generator is very tight. Is anyone running this or the B265 thru-hull transducer on an Express 330? If so, please let me know where you mounted it. Not interested in a transom mount but I know that is an option. Thanks!

Installer of ex owner installed my same size B265LH center keel on the fairing block and the position is exactly there where the lifting straps go and she got hauled with the rear strap over the transducer what is definitively not cool.
I am waiting to get a quote to pull the B265LH and have it glassed flush center keel to solve the drag issue and that the sling lift boat on it.

I believe the 330 Express has also the transducer pockets, but it seems to me that the original airmar fairing block is too big to fit in the pocket, but can maybe shortened to fit there. That would be the best place and should be accessible as designed by GW.

I can't remember how the 330 Express bilge area is, my B265LH is in the empty bilge space after rear fuel tank, approx 4ft forward of transom.

I don't know if mine is the same size but here's some info.

I installed an Airmar B175H to starboard of the ~6" high rib that's down in there. This is one of two structural ribs that you see in the aft bilge area.

There is a pretty decent sized flat area there and mine is a chirp with 20 degree tilt. I used a properly sized hole saw and sealed it with 3M's 4200 polyeurathane sealant. Works great and no leaks.

No it's a total different transducer, in shape and size.
The Airmar 164/165/175 series is a wide stem but very flat head transducer not needing an fairing block while the 265/275/285 are traditional shaped transducer needing in general a high speed fairing block, however, both are thru-hull transducers.
I did not measured the transducer installation pad/area but by eye measure the B275 fairing block will not fit there.

This is my B265LH and it's fairing block, the B275LHW has the same size
