Use a 6 point socket or box wrench, and cross your fingers.

may have to remove the manifold and riser or pull the engine.

Used a 24" socket wrench and the two bolts came right out. Now off to have it tested and likely put in a new one! I'll update this thread when its done. Crossing my fingers I'm at the end of my journey!

Don't forget to check out that ignition switch to make sure the start position works. Should apply 12V to slave C (Y/R wire) in start. Good luck.

So I put the key in the start position, drop 12V onto slave C and if it clicks, my ignition is good. If no click, ignition switch is bad? Can I do this with the starter completely removed?

Sure, but you have to be CAREFUL LOL. First remove the negative cable from the battery (very important safety wise). Find the cables and wires (with larger terminals) that went to the fuse. Connect them together with a small bolt and nut, and wrap them with some tape to make sure that it does not contact any metal. Replace the negative cable on the battery (should not have a big spark when you do that, if there is you have a short somewhere) and you should have power to everything. Turn the start key (puts 12V through the switch to the slave C) and the slave should click closed, and stay that way till you release the key. With key in start you should have 12V on A, B, and C. Release it back to run and should only have 12V on A. Everything else on the boat should work.

Well that is progress.... I guess. Your slave is OK but you have a HUGE short somewhere, most likely your starter. You drew better than 80 amps, so that would have melted most any of the smaller wires. Take a close look at all of the wiring, to see if anything looks like it got hot, use your nose too LOL. Time to pull the starter and have it checked out. The dash went dead when the fuse went, so no problem there, just got to check out the ignition switch. There may be a fuse there somewhere that went or it could be a loose connection or the switch. Should have it working in no time

So pulled the starter and it tested perfect. I checked my alternator's continuity and there are 4 posts on it. The one main orange coming from the starter solenoid and 3 blacks (I think they are black). All 4 terminals have continuity to the ground on the battery. Is this normal?

There are two wires coming off the starter solenoid, orange to alt and red to 50amp breaker. Since the 50amp breaker is not throwing, must the short be on the orange wire to the alternator?

Time to have the alternator checked out too. Sounds like you are getting close LOL.
