ARCO Marine Original Equipment Quality Replacement Tilt Trim Motor f/Early Model Yamaha - 3 Wire, 3-Bolt Mount

The ARCO Marine Original Equipment Quality Replacement Tilt Trim Motor for Early Model Yamaha is a direct OEM-specification replacement designed for marine technicians and boat owners who demand reliability in critical trim-and-tilt systems. Built to factory tolerances, this 3-wire, 3-bolt mount motor restores full operational capability to early-generation Yamaha outboards (70, 90, 115, 150–200 HP models) without the expense of a complete system replacement. Anglers, commercial operators, and recreational boaters rely on dependable trim functionality to maintain optimal running angles and fuel efficiency across varying water conditions and load weights.

This replacement motor features a robust 4-mm thick shaft blade with a 68.3-mm mounting pitch, engineered to handle repeated cycling under load while maintaining precise blade alignment. The three-wire electrical harness and ring terminal ends ensure secure, corrosion-resistant connections typical of marine-grade wiring standards. Original equipment quality construction means tolerances match Yamaha's factory specifications exactly—critical for smooth, noise-free operation and consistent pressure delivery throughout the full trim range. The compact footprint (5 x 4 x 10 inches, 5.45 lbs) allows straightforward bolt-in installation with no modifications to existing trim cylinders or mounting brackets.

Marine mechanics and outboard technicians specify this motor as a first-choice replacement when diagnosing slow, sluggish, or non-responsive trim-tilt behavior on vintage Yamaha powerheads. Compatibility is confirmed by matching your outboard's horsepower (70–200 HP range) and verifying the 3-bolt mount configuration and wire count before ordering. Installation requires only basic socket tools and roughly 30 minutes of shop time; the pre-wired ring terminals eliminate custom splicing and reduce electrical failure risk. For operators running high-hour engines or commercial applications, this OEM-equivalent motor delivers the same reliability and longevity as factory-sourced parts at a fraction of dealer pricing.
