Not my boat, but it is very close to, if not, an exact duplicate. The weather here has been miserable and I'm not in a big hurry to get on the lake in this heat. When it cools off, I'll try the following in this order
1 Get a good baseline with the current setup
2 Do more testing with variable engine heights
3 Move the trolling batteries to the front of the port rear compartment
4 Start playing with PVS plugs in the bravo.
5 Try the trophy.
6 Retry the Quad IV.
I'm trying to sequence the tests in the simplest and quickest first. If they don't result in improvement, then its back to the drawing board. If I'm missing anything, please post your suggestions.
