Using this ARCO replacement outboard tilt trim motor is easy. First, make sure it's the right fit for your late model Mercury engine with a 2 - wire connection. When installing, clean all the connections thoroughly to avoid corrosion which can affect the motor's performance. Once installed, it should work smoothly as it's been dynamically tested. As for maintenance, check the motor regularly. Look at the bearing surfaces of the motor shaft, which are hardened to resist wear, but still, keep an eye out for any signs of damage. The epoxy powder coating provides insulation protection, but if you notice any chips or scratches, it might be a good idea to address them. Remember, this product has a warranty. For leisure use, it's 12 months, and for commercial or racing, it's 90 days. You can extend the warranty by registering your product within 30 days of purchase on arcomarine.com/product-registration. If you face any issues, don't return it to the place of purchase. Instead, contact the manufacturer directly.
