Thanks for the info. I can see the blower motor. It is actually in the back. right next to the vents. There is two vent tubes and one motor. One vent doesn't hook up to anything the other goes to the blower motor. The problem is that I have the factor install Big Bertha Ballest system on the boat then tanks for it fit around the blower motor. This is going to make getting the motor off extreamly diffcult. Thought I had it over the weekend but the front tank is the one that the pump hooks to and that is on the bottom. So going to try a new approach this weekend.

Have a great day.
