I've gone over the setup on ours with Steve David. We have a couple of things that he saw stood out as probably no's. One is they ran silent choice with exhaust coming out 4, 4" outlets in the notch. The outside two are directly in front of the drives. The exhaust outlet is 1 1/2 inch long stainless tube. Messy water and who knows what else it does. Not a good design.
The other looks to be prop diameter maybe giving the stern too much lift.
