Boat in the driveway. Drive all the way up. Wife in the boat. You outside locating the "shift cable" on the starboard side. Look up & under while the wife moves the control lever. Ideally you will have the throttle cable disconnected.
You are watching for the sheathing moving towards reverse & it moving away looking for forward!

Re: alpha one shift problem

Here's a pic of the shift shaft on the drive. When it is postioned straight front to back it should be in forward. That would be confirmed by trying to rotate the prop by hand (engine off) CCW and see if it locks. (standing at the back of the boat looking at the bow)
