I have an '82 OMC V6. The 4.3 is essentially a 350 CI V8 block w/
two cylinders lopped off. Tilt is for bring up the drive unit when
trailering/beaching. Trim changes the angle of the prop relative to the
hull while running. On my OMC, the tilt is a spring loaded toggle
switch on the dash. The trim is located as a rocker switch on the
shift/throttle. It controls the attitude of the boat under power. Trim in
(toward transom), the nose goes down. Good for pulling skiers outta the water.
Trim out (away from transom), nose goes up and the boat rides more toward
the transom vs. wetting the entire hull. Less drag, more speed, not as
stable.

Power steering.... need to look at pressure. If your belt is there, it's
likely that the pump is out. Also check to make sure it has PS fluid present.
