Switching from an internal motor to an external motor can yield many benefits. Allows you to remove the motor box from the deck, leaving more room to work. Outboards can offer more precise control in maneuvering situations, and modern outboards are very efficient and environmentally friendly engines. The addition of the bracket to the aft end of the boat also extends the waterline, providing slightly higher speeds at displacement and planing speeds. Outboard wiring harnesses and control cables are easy to route and a fairly simple process, especially if you are mounting a new outboard and control package.

Step 1

Close the fuel valve and disconnect the negative battery cable. Remove all control, electrical, and cooling lines from the inboard motor. Unscrew the coupling from the driveshaft.

Step 2

Install the motor hoist and back it with it enough to keep the slack in the chains. Remove all engine mounting bolts. Remove the engine from the engine compartment.

Step 3

Install the engine mount on the transom. Lift the bracket up and hold it in position on the transom, then locate the bolt holes by marking the mirror through the bracket holes. Remove the bracket and drill through holes for the bracket bolts through the transom.

Step 4

Raise the bracket into position and install the bracket bolts. Apply blue Loctite to the bolt threads. Install the nuts and tighten them completely. Raise the outboard motor into position and mount it on the bracket.

Step 5

Remove the rudder from the top of the rudder and drop the rudder through the rudder post. Plug or plug the hole in the tiller post. Remove the propeller from the shaft and pull the shaft up into the engine compartment and off the shaft stem. Cap or plug the shaft stem at both ends. Remove the helm from the console.

Install the outboard control package. Mount the outboard helm to the console. Route direction and control lines down the middle or to one side of the platform. Place lines under deck whenever possible to reduce tripping hazards.
