71 silverline comoro

I recently was gifted a 71 silverline comoro. I'm having a hard time figuring out how to raise and lower prop. And I don't see a trim switch.

Raise and lowering the outdrive is more dependent on the type of drive you have. What type of motor (make) is it?

It's a 231 buick inboard out board

I dunno' if Mercruiser used the Buick motor or not, but OMC did.

Your drive is defined by the maker of the leg, not the engine. Do you know what make the stern drive is? They put the tilt switch in different places too. OMC was usually a toggle switch on the dash.

if its a Buick motor, its an OMC

it would be the 225 cubic inch odd-fire Kaiser/Jeep V6 back in 1971 (the 231 didnt come around until Buick bought the V6 back from Kaiser Jeep in 1974)

there should be both a Tilt switch and a trim switch. the tilt operates just the leg and is used for trailering.

the trim operates the small hydraulic unit under the front of the motor which moves the whole motor/drive/leg assembly

I don't see neither trim or tilt switch

Possible that the OMC doesn't have trim. It was optional with the Stringer.

On my Comoro the tilt and trim were the toggles like the one left of the ignition in this photo.

The switches are for blower, pump, lights and horn

That's an electric shift Stringer. The remote (throttle) has a red lever to run up the RPM in neutral, and then the throttle controller. Tilt is a separate toggle switch somewhere. Do you have any unused "holes" in the dash? Maybe it was removed?

The tilt motor is way at the back of the engine, port / passenger side. Might check to see if the wires are in tact.

Trim was different on the Stringers. If you have a big jackscrew on the front engine mounts (with a motor on it), then you should have a toggle for the trim somewhere too. But some of the Stringers didn't have that option, so there'll just be the engine mounts.

The only empty hole on my Dash looks like a cigarette lighter

Well that's certainly odd.

Any wires capped off under the dash? // There's no other way to do this on the Stringer: the remote doesn't have a switch for the tilt. It's a separate switch at the helm somewhere (unless for some weird reason it's in the stern - which I suppose is possible).

Otherwise, you have to track the wires from the tilt motor.
