2018 G2 250 Hard start

Hello all, I am trying to figure out why I am having starting issues. I have fully charged batteries, clean cables, good battery switch. My engine will not turn over when I turn key to start right away if it does at all. I cleaned coonections under top of cowl just to make sure of good contact there too.. When I put my battery/starter meter across cowl terminals and turn key it drops voltage from 12.5 to around 9. Sometimes it will go ahead and kick over and other times nothing. I know it's still under warranty but local dealer is 7-8 weeks to get to it. Anything else that I can check to try and get my boat running by the weekend? Any help would be greatly appreciated!

 

Thanks,

 

Spencer

I suggest a voltage drop test to find the connection that is a high resistance.
Put one meter lead on the positive cowl terminal and the other lead on the battery positive post. The meter should read no difference in voltage. Turn key to start and observe meter, it should read less than 0.5 volts. If it reads higher move to battery switch output terminal and retest. Also test the ground side cable.
One cannot say a battery switch is good without putting meter leads on the in and out terminals and checking for voltage drop under a load (engine cranking).

Thanks for input. I will test across switch this morning

On some of the earlier G2 outboards the battery cable posts on the cowl would either loosen or may not have been torqued sufficiently on the production line. 

Also put the digital voltmeter leads on the battery posts, not the cables, and read the voltage when the motor cranks over or tries to. If it drops below 10 volts, it is either faulty or partially discharged. If there is more than about 1 volt difference between battery voltage and cowl voltage, there may be bad connections, cables, or switch (if equipped)
