This 25", high thrust outboard is a popular outboard with PDQ catamarans and sailboat owners who want a manual tilt, remote model. This motor has a on-engine manual choke only. SIM Yamaha does the conversion and fully test runs the engine before shipping. It is necessary to determine whether the boat has a 7-pin or a 10-pin control.
