## Description

Description: SE Sport 400, 40-unlimited HP - Gray

Review: Good performance - Great performance but I had to cut a small piece to fit my 50hp honda
Review: Purchased for a Worldcat 255DC with 150 Yamahas. These are easy to install at the sandbar using the supplied hardware, a 7/16" wrench and Phillips screwdriver. I was able to baseline the boats performance prior to installation, but I have not re-evaluated post installation data yet. These were installed when the boat was at full fuel, and an excess of gear and people aboard. One thing I can say for sure though is that it has gotten the boats tendency to porpoise under control, which was the main reason I wanted to install them. They work. Up on plane at lower RPMs and definitely a smoother ride and less fiddling with the trim control. I've been checking the torque on the nuts and have re-tightened a couple times. I will drill through mount these soon since they are of noticeable benefit.
