Got a Yamaha outboard with a tired or broken trim motor? This ROP Shop replacement assembly is here to get you back on the water. It's designed to fit a wide range of Yamaha marine engines from 1997 and up, covering 115, 150, 200, 225 HP models (please double-check your specific year and model – we can help if you're unsure!). It's a 2-wire system with ring terminal ends for easy connection, and it uses a 4-bolt mount. The kit includes the motor itself, a necessary O-ring, and an adapter, just as shown. IMPORTANT: This motor is NOT for pumps that have a channeled or grooved round base where the pump meets the motor. Please check your old unit first. We know compatibility can be tricky, so if you have your model, spec, serial number, or horsepower info, just ask and we'll help confirm the fit. Nobody likes returns, so let's get it right the first time. Stay rugged out there!
