figured I would start a fresh thread for future searches.
Had part of a day to play with the Hill Marine 4x4 20P props on my Bravo 3's. For reference, I changed from the Merc 22P props.
Acceleration: From idle speed to plane: drastically improved and very smooth. Almost no digging of the aft, very little bow rise. Tabs down/drives down. Very noticable acceleration while on plane too.
Planing: little to no drive trimming needed. Was able to stay on plane at ~21mph w/o tabs. Again, very responsive accelerating from 21-30 mph. Interesting the wake behind the boat from the props is smoother looking too. Speed vs rpm I found no loss from before. Still need to make a WOT run.
Coming off plane: 342 owners know of the swimplatform wash. I still have that but it is MUCH less. The aft does not dig in like it did before. Idle speed / no wake speed is good at ~5mph. With the less churn from the props I can even pick up the speed at bit too.
Docking: For the first time the boat will truely 'spin' on point. Low speed response improved. A definate win.
Engine sound: This was a big suprise. The engine noise at plane is WAY down. Easily have a normal voice conversation now. Obvioulsy working less hard. Sounds smooooth.
I'll add more info as I get it. Might be the best $ I spent on this baby. lol. All thanks to this forum or I would have never tried them. So +++ to the guys who posted on these this year!
Some VV mobile screen shots to follow.
