Took the boat out last week & I could not get it to start........Tested the batteries & both are 12V +. I turn the key & nothing happens. The kill switch is on "Run" so that is not the issue. I've checked all my wiring connections & they all seem to be OK. Checked the solenoid & it tested OK. I have also lost power to the tilt trim. Called my local boat shop & they are out 3 weeks, so I would really like to resolve this myself. Any & all help will be appreciated.
