Using this ARCO Marine tilt trim motor is straightforward. First, make sure it's the right fit for your Yamaha outboard based on the specified model years and horsepower. Before installation, clean all the connections to prevent any resistance that could affect the motor's performance. Once installed, you can enjoy the smooth operation thanks to the dynamic testing it has undergone. When it comes to maintenance, regularly check the motor shafts, which are built to resist wear. Also, keep an eye on the epoxy powder coating to ensure it remains intact for insulation. Remember, for leisure use, you have a 12 - month warranty, and 90 days for commercial or racing. To extend the warranty, register your product within 30 days of purchase on the ARCO Marine website. If you face any problems, don't return it to the place of purchase but contact the manufacturer directly.
