If the terminals look good, try tapping the starter with a phenolic hammer or the wooden end of a metal hammer while cranking. If you find rust or corrosion, turn off the battery switch and remove and clean the terminals. Examine all wiring connections, especially at the starter.
If the battery has good voltage (12 volts or more) the problem likely will be at the starter. Keep in mind that at 12 volts a battery has about 50 percent of its capacity remaining, and at 11.5 volts only about 10 percent remains. Boaters often underestimate the condition of a battery based on the voltage. Parallel switches work well when you have a healthy battery that is low, but not when the battery has a severe problem. Here’s why: If the start battery has a bad cell, when you parallel with a good battery you weaken the healthy battery. If you have the option to select an alternate battery, that is a better approach than using the parallel switch. Some boats have a parallel switch for engine starting.

Start the engine from an alternate battery, or start the generator and make sure the charger is working. If it’s between 0 and 8 volts, you have a battery problem. Check voltage at the start battery (while cranking). If the voltage reads between 0 and about 8 volts, the problem is either the battery or the starter itself. If yes, then refer to Shake Hands With Solenoids column to troubleshoot and do a work-around. Make sure the battery switch and the ignition circuit breaker are in the on position. Check voltage at the battery posts and if you find good voltage there the problem lies between the battery switch and the start solenoid or in the solenoid. If the voltage reads “0” the problem is somewhere between the battery and the solenoid, including the ignition switch circuit and the solenoid itself. The voltage will fall into one of the three following categories. While your partner tries to start the engine, test for voltage on the terminal connected to the starter with the positive meter probe on this terminal and the negative probe on the engine block (make sure you have a good connection-preferably find an unpainted bolt or scratch through the paint). The wire from the battery connects to one terminal, and the other terminal sends current to the starter. The solenoid has two larger terminals (see “Shake Hands With Solenoids,” October 2014). You might be able to eliminate a host of possible causes by checking for voltage at the starter solenoid. First check the voltage of the battery, either at the main panel or with a multimeter at the battery posts. If the engine still doesn’t start, the neutral safety may have failed, and it might be necessary to temporarily bypass this switch to get the engine started.Īssuming that the shift lever was not the problem, start the troubleshooting with the start battery, battery switch, and ignition circuit breaker. Move the lever in and out of gear a few times and try again. Many boats have a safety mechanism to prevent starting the engine while in gear.
