Thanks!

WR,
Welcome to the madness! You found a great place for info, as you've already seen.
Concerning the Simrec drive shower, we installed one on the Factory-1 Active Thunder. Ours was the model that required two small holes at the tail of the cavitation plate and ran under the wing-plates, (dual-ram hydraulic steering). I would love to tell you I never abused my drive.
too many people know better.
I CAN tell you, After a number of races ant LOTS of time at speed, we never experienced a drive failure.
Hope this helps.

The ONLY Bravo the Simrek Halo Max will not fit on is the Bravo XR SpeedMaster and the Bravo XR SportDrive.

There is a very good demo video on how to install a Halo on a Bravo and a very good underwater video with the Halo Max in operation. Check it out.

Was planning on ordering one, good thing I didn't, have the XR drive

Will fit on the XR drive as long as it's not a SpeedMaster or SportDrive.

Including Bravo 3 XR?

I spoke with the designer of the Halo Max and the Summit Max Drive Shower, He said they will fit on the Bravo III XR. As long as your outdrive in not silver or SpeedMaster or SportDrive.

Cool thanks

Wags Engineering makes a nice shower/billet top cap kit. Little pricey, but a nice product. And im not implying Simrek isnt, just another option.
