The starter motor will have brushes made of copper and carbon alloy, which are in housings on the endplate of the starter. Most starter motors have to be removed and partly dismantled to inspect or replace brushes. [links]

There will be many instances when your battery would show the voltage level above 12.6V, but still, your boat won’t crank up and clicks. That’s when you need to check the starter and the solenoid.

These brushes wear out, which results in inadequate electrical contact. By gently tapping on the back of the starter with the hammer, the brushes can be knocked back into place so they can make contact one more time.

Sensor, not gauge, correct? Located on engine? [links]

When i replaced the ignition I used:
Yellow/Red - Start
Purple - Ignition
red - Battery more

Did you check the oil pressure sensor? here

I did not solve my problem last fall so I'm back at it this weekend and hope to have some help from this forum. To add to my previous post I connected the fuel pump directly to the battery and it is working so it isn't the fuel pump.

If it reads more than about 8 and less than about 10, it is likely that the starter or the engine has seized or you have excessive resistance in the starting circuit from poor connections, or resistance inside the solenoid. See above for steps to try related to the starter. If the engine is seized, you either have an internal failure (game over), or the engine has one or more cylinders filled with water, known as a hydro-lock. The pistons and cylinders compress air to generate heat, but water cannot be compressed and the piston stops once it comes up against the liquid, preventing the engine from turning over (and sometimes bending connecting rods in the process). here

Assuming that the shift lever was not the problem, start the troubleshooting with the start battery, battery switch, and ignition circuit breaker. First check the voltage of the battery, either at the main panel or with a multimeter at the battery posts. You might be able to eliminate a host of possible causes by checking for voltage at the starter solenoid. The solenoid has two larger terminals (see “Shake Hands With Solenoids,” October 2014). The wire from the battery connects to one terminal, and the other terminal sends current to the starter. 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 voltage will fall into one of the three following categories. [links]

Before doing any troubleshooting, check the shift lever position. Many boats have a safety mechanism to prevent starting the engine while in gear. Move the lever in and out of gear a few times and try again. 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. [links]

This practice should only be attempted on older Bendix type starters. On the newer planetary gear starter motors tapping might damage the internal magnets and therefore should be avoided. [links]

If the voltage reads “0” the problem is somewhere between the battery and the solenoid, including the ignition switch circuit and the solenoid itself. 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. Make sure the battery switch and the ignition circuit breaker are in the on position. If yes, then refer to Shake Hands With Solenoids column to troubleshoot and do a work-around.

Electric fuel pumps can easily go bad from just sitting. The fuel turns into varnish and the pump fails. If you are going to let your boat sit for 6 months or more, you should run Fuel Stabilzer through the fuel system.
The Fuel Stabilzer will keep the fuel from ruining the fuel pump. here

Your local Auto Parts Supply Store will usually sell a Spark Tester. Get the best spark tester they have. This is a great tool to keep in your boats tool box. Remove the main coil lead from the center of the distributor cap and install the Spark Tester. Make sure the other end of the tester is attached to a good clean ground. Crank the engine and check for spark. If you have no spark, there are several things which can be at fault. [links]

If you have fuel, you need to check for spark. Careful! Mercruisers have a powerful ignition system that will shock the hell out of you! [links]
