AGGRESSER Sponsons

​AGGRESSER Sponsons for STXR Slicing and Dicing
 This month we look at the AGGRESSER Sponsons for the STXR. At first look, they are the thinnest sponsons we have seen @ ¼ inch thick, they definitely have the market cornered as the thinnest sponsons available. Okay, I know what your thinking. Since they are so thin they must be weaker? WRONG, They are made from a material G-10 that is very strong. This material is a woven fiber incased in resin. It is similar to Fiberglass but stronger.
Another big difference with the AGGRESSERS, is the fact that they do not use a spacer plate, They bolt right to the hull. When we flip the Aggresser fin over and look at the backside, you will see it is machined to fit the hull with an angle cut. According to Bobby at AGGRESSER, when you are in a turn the fin will be straight up and down acting like a rudder/skaggs in the water. This helps with hook up and gives you a slot car type feel in the steering. Bobby also mentioned, by not having a spacer plate you will not experience any flex in the fin and that will give you more consistent and predictable handling with the benefit of your jet pump staying hooked up. The reason for better pump hook up is when you add a spacer plate your widening your hull (like have pontoons on the side) and with these 2 seater and 3 seater hulls they are already wide enough, not to mention that it would create boat lift and help the pump become unhooked when running spacer plates. So you can see it is an advantage not to run a spacer plate and to be as thin as possible.
Lets put them on! First, we removed the stock sponsons and spacer plates, then we proceed to clean the hull where sponsons will be placed. I added thick beads of silicone to the back side of the AGGRESSER fin, then added screws using the stock holes and tighten, same for other side. Its an easy install.
Now for first ride, you notice right a way an improved and controlled ride. The STXR felt like a slot car or corvette on steroids, impressive! You will notice how the STXR cuts through the chop with ease. Now, for the real test, hitting a hard right turn! The STXR stuck like glue in the corner! I would say the AGGRESSER’s are a valuable asset for any sport rider, rec rider or full on pro rider!
They also have them for Sea Doo, Kawasaki, Yamaha and Honda
