Fuel Systems

The easiest way to work on the sending unit is to remove the floor and the console as a complete unit. Unscrew the floor and lift up the floor and console together. After you remove the screws cut out the silicone in the floor grooves. You can attach a rope to the stainless grab handles and use a hoist to break the floor loose from the silicone. Once the floor is loose lower the rear of the floor & raise front of the floor until high enough to remove the fuel sending unit. Go slow. When you lift the front of the floor closely observe the wires to make sure everything is moving freely. You might have to remove the drain hose from the baitwell.  Install the new fuel sending unit, verify other gauges work, lower floor back down and reinstall screws & put a new bead of silicone in grooves. This sounds like a lot of work but it usually only takes about an hour.


Location – The serial number on your Shearwater, Sterling or Blackwood boat is located on the right (starboard) side of the transom, just below the rub-rail molding.
HIN Identification Code – The first three characters in every HIN are a Manufacturer Identification Code – in your case “SOE”.  This identification code is issued by the Coast Guard.
Hull Serial Numbers – Characters four through eight are the hull serial number, which consists of two letters identifying the model and three numbers representing the serial number of the boat.
The Date of Certification – The ninth and tenth characters in each Hull Identification Number indicate the month and year of the date of certification.
Model Year – Characters 11 and 12 are the model year of the boat.

The cast net box is designed to pump out any water that enters the boat.  The plug should always be installed in the cast net drain. The floor drain plug should also be plugged to keep water from entering through the transom scupper.  The scupper is not a reliable water stop.  The floor drain and cast net box can be unplugged if the boat is moving forward and water will be sucked out of the boat by the vacuum created at the transom.
