Since I was kind of in a rush to finish the conversion to electric propulsion back in 2008 some things did not get installed as well as they should have at first. One of the things that was done in a temporary install was the electric propulsion speed control. Which at first was just secured with Ty Wraps as you can see here:
Next I drilled the hole and routered out and sealed the deck core with thickened West System Epoxy so no damage or delamintion would occur if there should be any water leakage:
The fitting I used I was used a standard deck water fill fitting:
I removed the chain and fitted and secured it into the deck.
wire pull rods I carry on board to help make this a little easier:
Hard to see in the photo below but, I cut a small slot down the side of the top of PVC pipe to allow for the wires (NOTE: I also created a drip loop so water would not run down the wires into the boat) and fitted the top with a removable PVC cap that allows for the easy installation of more wires or removal of existing ones as needed:
