Got the boat from eBay with the sharpie mark of shame on the inside of the hull, but there was no damage, and even included the parts listed as missing in the auction description. Bonus for me. I initially installed an OSE flexshaft, OSE upgraded strut, and an Octura x642 S&B prop from RC Chief. Drilled out the cooling inlets and output, installed larger diameter cooling hose and routed it through the bottom of the motor first (shipped connected to top of the cooling can) and ran it on Turnigy Nano-tech 2S 5000mAh 35-70C batteries.
First run was a disappointing 36mph. My Blackjack 24 was running 34mph on 3S at the time

Took it home, readjusted the strut, anad managed 38.3mph the following day.

Bigger issue at the time was a complete lack of range with the motor cutting out after a turn. I chased my tail on that issue for a while, replacing the transmitter (wanted a new one anyways), checking connectors, added a capacitor to the receiver, then finally replaced the receiver. It wasn't the new receiver that fixed the problem, but as soon as I pulled the old one out and compared it, the problem was very obvious...

The non shielded part of the antenna had been broken off, leaving only shielded coaxial wire. Yep, that makes sens. Stripped back the shielding, added a little heat shrink, range issues gone.
Spent a little more time aligning the motor to the flexshaft, tweaked the strut a little more, and maxed out what I feel is the limit of 4S performance on this boat, 41mph.
