Got a hill sl4 last week been playing with ptp. Lost about 4 mph but it’s gonna be a great fishing prop. Handles so much better than the txp 3 blade I was running. Lifts entire boat with plenty of bow lift as well. At 75 its like driving my pickup. Ran a borrowed ot4 couple weeks back 79 and change with it just hard to find one. But I know the boat has more in it still playing with setup. 76.4 full tank all of bps in front storage and partner with half of bps in rear.
