Are you in trim for the season? Trim tabs can give a better ride and save fuel when set properly. Get them fully functioning before your summer cruise

1) How do I check if my trim tabs work? If you can borrow a second pair of hands, check that both trim tabs extend and retract at the same speed and range. A rough guide that the ram should extend between 4 – 6 inches.
2) Do I need to change or top up hydraulic fluids? The fluid in the reservoir should be clean – if the fluid is cloudy this is a sign of water ingress into the system. The fluid level should stay within the guided level when operated in both bow up and down position.
3) How can corrosion be prevented? Trim tabs need sacrificial protection to avoid corrosion, usually a small bar anode fitted to the inside ram bracket. We advise to add a disc anode to the topside of each tab.
