Using Your ARCO Marine Replacement Outboard Tilt Trim Motor: First, make sure your Yamaha outboard matches the specified models (2002 - 2009 200 - 300 HP 2 - Stroke and 200 - 250 HP 4 - Stroke). Connect the 2 - wire connection properly and use the 3 - bolt mount to secure it in place. Remember to clean all connections before installation to ensure smooth operation. Maintenance Tips: Periodically check the motor for any signs of wear. Since the motor shafts are hardened at bearing surfaces, they're quite durable, but a visual inspection is still a good idea. Keep an eye on the epoxy powder coating; if it gets damaged, contact the manufacturer for advice. Warranty: You have a 12 - month warranty for leisure use and 90 days for commercial or racing. Register your product within 30 days of purchase on arcomarine.com/product - registration to get an extra year of warranty on rotating electric ARCO products. Returns: This product can't be returned to the original purchase point. If you have any issues, contact the manufacturer directly.
