How to Find a Starter Solenoid for an Outboard Motor

The solenoid on an outboard boat motor is a relay that initiates the starter. The solenoid activates when the key and ignition are turned. The solenoid sends a burst of amperage that turns the starter. If the solenoid on the outboard goes bad, the starter will not turn over. Finding a replacement starter solenoid for an outboard motor is a fairly straightforward task that does not require much more effort than picking up a telephone or visiting a marine parts dealer.

      Lift the old solenoid out and wipe if off well with a shop rag. Examine the solenoid carefully to see if there is a visible part or model number. If so, write it down. If not, jot down the specifications of the outboard itself -- namely the make, horsepower and year if known. This information can also be found in the engine's owner manual.

      Call or visit a marine dealership and give the relevant information to a customer service agent. She will look to see if the part is available or will order it for you if it is not.
