Cavitation in chop

[Bobros]

Just bought a Sea Ark tunnel with a 60/40 jet and have a issue with what i think is cavitation in mild chop. Any suggestions for a fix?

Tunnels are notorious for creating cavitation in chop. Very slight adjustments up or down (and even slightly offset right or left) can make a huge difference.
I had to swap motors last weekend on my tunnel hull and I'm regretting it. It takes a lot of trial and error to find that sweet spot.
I may also try the intake fin kit.
Good luck.

Slow down or lower your motor. If you motor has power trim, slow down and trim down. It's worse in following seas.
