Using this ARCO tilt trim motor is easy. First, make sure it's the right fit for your late model Mercruiser with an Oildyne pump. Install it carefully following the standard procedures. When using, keep in mind that you should clean all the connections regularly. Corrosion on the connections can cause problems and reduce the motor's performance. For maintenance, since the motor shafts are hardened at the bearing surfaces, they're quite durable, but still check them occasionally for any signs of wear. The epoxy powder coating provides insulation protection, but avoid exposing the motor to harsh chemicals. If you face any issues, don't return it to the place of purchase. Instead, contact the manufacturer directly. Remember, registering your product within 30 days of purchase can get you an extra year of warranty for your rotating electric ARCO product.
