3.0L mercruiser will not Start.

[Road1]

Hello, I have a 2007 Glastron MX 175 with a Mercruiser 3.0L
engine that will not start. I tried to start it a few days ago and all i got was a clicking noise when i turned the key. I checked the battery and it was dead. I placed a Brand New battery in the boat and now i get nothing. Not even a clicking noise which i was getting before. I turn the key and nothing happens. I do however get power to my gauges, blower, tilt, radio, and lights. I have already cleaned all
connections to the starter. Checked battery cables. Checked fuses. What could it be?

Do you have a battery shutoff switch? Run more than 1 battery? Did you happen to install the battery backwards? (that would blow the fuse on the starter, and cause no power to the motor) even though your accessories may work. (lights would backwards, surprised if radio would though).
Get a DMM or test light and start testing at the battery and work your way to the starter.

Using a remote starter switch or a screwdriver, short the solenoid on the starter itself,
Starter works: check slave solenoid, check for 12V on the red or orange wire on the key switch.
Starter dosent: check all battery cable connections especially the block negative.

I run only one battery. No battery switch. Battery was also hooked up correctly. Battery was not put in backwards. Could it be the 90 amp fuse attched to the solenoid?

Yes, mine was blown on the boat I bought and the engine was dead to the world, until I replaced the fuse. If it's the starter fuse get ready to pony up $25

Like Jason said, use a DMM and ohm out the fuse to see if it has continuity or if it's wide open,,, or see if it has 12V on the engine (not starter) side of the fuse.

Check the battery ground cable. Follow it to where it is bolted to the engine.
