    thank you for the word of caution! Is there a way I can isolate that fuse to check if it’s the fuse itself, ie remove fuse entirely and test? Also, Should I remove started and have that checked?

    Not much knowledge on electrical stuff but In regards to the 90amp fuse. I am getting power from the batt side.

    Ok update time! I took the mutimeter around. Batt is good and some of the wiring was corroded. Went around with tester and cleaned connections under helm from batt to starter/solenoid, and behind alternator. I have 2 questions: 1. I’m getting a good reading to the 90amp fuse from batt side but low on outgoing side. Could it be a blown 90amp? 2. 50amp circuit breaker..mine has the red reset and a yellow arm looking thing that swivels. When I push the red button in it doesn’t stay in. Is it supposed to?

    When I turn the key, there is nothing, not even a click or sound or cranking.

    Has anyone changed the impeller on their own? How difficult/extensive is this job? Any write ups or videos?

    Yes, I’ve wiggled the key, Ive wiggled the shift to make sure it’s seated in neutral. I’ve also made sure the switch with the lanyard is on and also toggled that a few times to make sure it’s seated correctly. I’ve reset the breaker on top of engine. I have 1 battery, and the impeller hasn’t been changed. I will order the parts and have that done. I’ll take the voltmeter next and check places. I just wanted to make sure I wasn’t missing the easy stuff to check first. Thanks for the replies and I’ll keep y’all posted!
  9. Newbie with first boat so please forgive my ignorance! Bought brand new h2O sport 19’ back in 2013. Mercruiser 3.0MPI. Fast fwd to now...2 issues. 1. Boat won’t crank but nav and court lights came on, blower, horn, depth accessory all work. However, Radio does not come on and the Gauges do not move. Replaced battery, still nothing. Started checking fuses but got overwhelmed-so many!!! Any suggestions on what this may be or at least the main places I can start checking? 2. The last time I took it out. Loud audible warning to indicate engine overheat. Water pump? Impeller? I’m fairly mechanically inclined and would like to at least check on some things myself before I have to bite the bullet and take it to shop. Thank you in advance!
