SUZUKI STARTER MOTOR 31100-94702

Function and technical context

The starter motor is the electrical component responsible for rotating the crankshaft of the outboard motor when starting, providing the necessary torque so that the combustion engine can start its cycle. It works within the electric starting system, receiving current from the battery through the solenoid and transmitting movement through a pinion that meshes with the ring gear of the engine flywheel. In two-stroke engines such as the medium-power Suzuki DT models, a starter motor in poor condition can prevent the engine from starting, render the boat inoperative and, in emergency situations on the water, pose a real risk to the crew. This starter motor has Suzuki reference number 31100-94702 and is manufactured under catalog reference PH130-0075.

When to replace this part?

The most common symptoms of a damaged starter motor are: the engine turns slowly or with difficulty upon ignition, a dry click is heard without the engine starting, the pinion does not mesh correctly with the ring gear, or the starter emits squealing and knocking noises when activated. In outboard motors that are used frequently or have intense sailing seasons, it is advisable to inspect the starter motor at each seasonal inspection and check the condition of the brushes and the collector with special attention after 500 hours of operation. Replacing the starter motor preventively at the first symptoms avoids being stranded at sea and requiring costly emergency assistance.
