I am converting from a pitot fed speedometer to a GPS speedometer. I will no longer be needing the hose running from the lower unit though the transom and up to the dash.

Does anyone know of anyone making a plug or block off for the lower drive and for the hole through the transom assembly? I want to do something a little more professional than just cap the hose or crimp it shut.

Just take off the small piece of hose on the front of the drive. You can leave all the others in place. Maybe just plug the one behind the dash to be safe. That way, you could pull the GPS when you sell the boat and put the old speedo back in.

You can remove the hose barb behind the motor and install a pipe plug into the fitting that goes thru the transom housing. I believe it is a 1/16" NPT. Don't turn the main fitting, just the barb. Unless you want to remove the speedo hose completly on teh outside.

Takes a little effort to do, but doable.
