I am pretty happy with the S/S 4 blade prop. Trouble is I don't have anything to compare it against. Tows pretty good. I do more towing (tubes) versus speeding around the lake. LOL.
I have a tower already...I just want to add some tower speakers. Have my eye on a set of Aluminium cans with RockFord Fosgate 2-way speakers, and an amp to power them plus the two oem speakers, the ones that sit by my feet. I also went and purchased a Bazooka Tube (8") that I plan on mounting in the cooler compartment or the engine bay. It has its own amplifier, so no need to run a bunch of wires to the sub.
