Prop will not engage while in forward

Hello All,
Please forgive my ignorance as I am a beginner at this. This is the first boat I have had and my first posting. I have no troubleshooting manuals or reference pictures, so anything you can offer would be great and greatly appreciated.
My current engine is a Mercruiser engine (3.0/130 H P) Alpha One stern drive right hand prop. I bought this boat used 1 ? years ago and had it running the day after we bought it. Since it?s purchase date, it has not been in the water. The other day, after 1 ? years, I got the engine started again in preparation to start using the boat. I was able to disengage the throttle so I can rev it up and down. I cycled 2.5 gallons of premium unleaded for this process. So here is the problem/question. After re-engaging the throttle and pushing the throttle forward, the propeller barley moves. I believe that the propeller was only moving because of the vibrations. While the throttle was in the forward position, you could hear a ?cling, cling, cling, cling, cling? sound, almost acting as if the gears were not engaging. However, if I bring the throttle back to neutral and then move it to reverse, the propeller engages and spins, fast, as expected.
After reading a post similar to this, I found that while the engine is OFF, if the throttle is in neutral, the propeller will be able to be spun to the right(starboard) and to the left(port) freely by hand. When the throttle is in forward, it will spin starboard freely but will not be able to be spun to port. When the throttle is in reverse, it will be able to be spun to port freely but not to starboard. So I test all of this and all checks out. When it was in forward I could spin it to starboard freely but could not spin it towards port. So why will the propeller not spin toward starboard when the motor is ON and the throttle in the forward position?

Thank you, in advance, for your time and assistance

Gary

You didn't say how old the boat was.If it's only a year and a half then the cable probably needs adjusting.
If the boat's older(like I think) then you probably need a shift cable.
Any and all info will help.Age/type/salt or fresh,anything.Jerry

The boat and motor are original. They are boath 1987. The boat is a sunbird corsair. Best to my knowledge, it has only been in fresh water.

Could you explain why you thing it would be the shifter cable since reverse does work but not forward?

thanks,
gary
