Wow, thanks for sharing.

Didn’t think barnacles would grow that widespread in there.

A number of years ago, I had sheered a few teeth in the upper gear of a Bravo III. At the time it was sounding like a coffee grinder. I tore it down to investigate the noise and found the sheered teeth. The process requires that you split the outdrive. I found the same thing. I had also been running just slightly warm at the time, despite new manifolds, risers and impeller.

At the time the B3 was probably 14-ish years old. The case was also showing signs of corrosion, so I just replaced the outdrive.

Quagga Mussels have become a big issue on Lake Powell, I've heard stories of boats over heating due to them clogging up the intakes.....

Barnacles used to regularly clog the water inlets on the Bravo III as well. I used to use a mask and snorkel with an awl to ream out the holes every weekend, otherwise, I would start to see temps rise.

This doesn't surprise me as the current moves water over this area providing a food source to the barnacles but inside the water tube the fresh food supply is much less and I did not expect to see them get to that size.
