Upgrading hydraulic trim tabs to new advanced ‪@ZipwakeAB‬ system on a trawler yacht like the 3288 should make good sense. This video show some of the process. We chose to continue to use four tabs (even though the Zipwake Interceptor system should be more efficient), and fitting them between the prob-runnels to give them maximum grip. As is evident in the install of the new system cleaned up the transom quite a bit, and should also benefit the flow of water to the aft-truster. We will follow up with a video when we get to the sea-trails.
