Location: Uxbridge Ontario | Looking for an easy "how to" on moving the engine up and down a few holes on the transom.
Also, is there a rule of thumb of where the anti cavitation plate should sit in relation to the bottom line of the boat?

| Eventually someone will respond to your question. It probably would be a good idea to tell what boat and outboard motor you have. The height varies depending on the boat, motor, etc.
I've heard 1" above the bottom is somewhat common. You might ask a marine dealer. | |

You will need the top screw on fitting that has the lift bracket built in, that will allow you to lift the motor and re-bolt it where you want it. Don't try the wood block and trim deal you are sure to hear about unless you have competent and strong help. generally, the cavitation plate should be slightly above the keel using a straight edge on a standard hull, and as much as 3" or more above a padded hull. | |

Here is what SWorrall is talking about. It works well and if you have just a touch of a mechanical ability you can do this without any real issues.
To raise the motor, all you need are the correct wrenches, your tie down straps, your trailer (chocked front and back both sides) and a block to go under your skeg.
After attaching your tie down straps and tightening the boat to the trailer at the stern, lower your winch so that the tongue of the trailer is as low as you can get it. Next, use the trim button to level the motor with the ground, then place blocks of some sort so the skeg is resting on the blocking.
From there, remove the upper mounting bolts from the transom. Clean any silicone residue off and set them aside for reinstallation. Assuming the lower mounting bolts are in slots, loosen the bolts without removing them. Here is the fun part....the motor is probably still tight to the transom for the most part due to excess silicone around the bolt holes...with a little effort, the motor will come loose from the transom by rocking it back and forth (sideways on the transom).
Now all you need to do is go to the front of the boat, crank up your winch to raise the front (which lowers the stern) until you reach the correct bolt hole you wish to mount the motor in. Since the lower bolts are not removed, the motor will stay level as you raise the trailer. ( might be nice to have a second set of eyes and a set of hands to steady the motor if you are worried about it....never hurts)
Once you have the bolt holes lined up, reinstall the upper mounting bolts (don't forget silicone first) tighten up, then tighten the lower mounting bolts. Give the silicone a couple of hours to set up and you are all done.
Once you do this process one time, you'll have no problem doing it again if need be. Not too hard overall...
