The budget way to monitor a boats DC electric is to wire a set of terminals to the dash area from the big contact an the starter , and the starter case..
Plug in that harbor Freight meter before staring, observe the volts, 12.8 or so, crank away on the starter , usually 9.5 volts in minimum while cranking.
When the beast starts look at the meter again the V should now be higher than before the start.
After an hour or so the V should be about 13.8 to 14.4 , all is well.DONE!
