First trip out and my bilge blower is not working. I checked the fuses and they are all good. I know nothing else about it...I do not even know where the blower is located.

What can I check? Where is the blower?
 
If you open your engine compartment there is a hose which looks like a dryer vent hose. The bilge blower will be in line near the top of that hose. It's easy to replace.
 
Man! They sure don't leave much room to work!<br><br>I am getting power to the plug the fan plugs into, but no power to the fan. I removed the fan, rigged up some wires to my truck battery and when touching the terminals in the plug on the fan, it works! I am stumped!

HELP!
 
If power is making its way out to the blower through the boat's wiring and switch and fuse; and you can power the blower independently off of a battery, I would say you have a bad ground. To test your ground run a jumper wire from the boat blower + lead to the blower + lead and ground the - lead on the blower to a good known ground. If the blower works, you have your culprit

When I am checking the harness connector, I am using my meter and sticking the black probe into the negative side and the other into the positive and getting almost 12v...that doesn't indicate a good ground?

Not necessarily. You are measuring the circuit voltage in a 'no load' condition.
Follow sibnai1's advice above - remember check for fumes first! Should you accidentally create a spark.......
Hook the positive side up as normal and ground the negative side of your blower.
 
I cut the connector off the fan and used jumpers from the boat harness to the bare wires of the fan...still nothing. I moved the negative jumper from the boat harness to the boat battery...still nothing.

Measuring the ends of the two jumpers when coming from the boat harness, I measure 11.2 -11.5 volts. Shouldn't this be enough to run the fan?

My next step is to cut off the boat harness connector, but this boat is so new, I hate to go hacking into the wiring!
 
Could be loose/intermittent wire in the connector or fan. The blower in my 175 gave out after 5 years and it was $40 on amazon. Might be time to get a new blower regardless as you already have things open.

If you are getting 11.2 - 11.5 at the harness, measure your batteries next. Go right to the posts. If its higher at the battery terminals, you have a connection issue some where between those two points.

A couple things about the 11.2 to 11.5 you are seeing a) it seems kinda low and b) again, this is an open circuit voltage (no load) so you cant really say that its enough to spin the fan because when you 'load' the circuit, if you have a bad connection, it will drop like a stone.
 
I ran out of time! It was time to go back to work today and my wife needs the boat for July 4th for a lake party so I took it in to the shop.
