I HAVE A 1968 EVINRUDE SPORTSMAN 155HP V-6 TRI-HULL. I CAN HEAR THE TILT MOTOR RUNNING, BUT THE OUTDRIVE WON'T GO UP. DID IT SHEAR A PIN, OR WORM GEAR, OR SOMETHING ELSE? CAN I FIX IT MYSELF OR DO I NEED TO TAKE IT TO A MARINE MECHANIC?

HI I have the exact same boat in fact I am taking the kids skiing tonight behind it. Usually what happens is the end of the coupler or the tilt motor shear off from lowering the unit too fast. If you can find a dealer who is willing to work on it I would highly recommend it. removing the tilt motor from the inside is a royal pain and is even harder to get back on. You can remove the plate on the outside and inspect. If the worm gear is not going around then either the coupler or the end of the tilt motor is broken and will need to be removed.
CAN IT BE DRIVEN THIS WAY OR WILL I DAMAGE THE OUTDRIVE?
WHEN I PUSH THE ROCKER SWITCH TO LOWER THE OUTDRIVE IT WOULD LOWER AS YOU WOLOLD HOLD THE SWITCH AND STOP IF YOU LET GO. RECENTLY, IF YOU JUST TOUCHED THE SWITCH THE OUTDRIVE WOULD FALL ALL THE WAY DOWN.
You can drive it just be carefull when you put it into reverse. The outdrive will come up and then slam down when you put it back in forward.
That is not unusual. There is like a clutch behind the small plate that is on the back of the boat. Mine just comes down when you hit the down switch. Which is usually OK as long as you dont hold it down.
