Look up any late 70's or mid 80's 55 hp and the tilt lock is pretty much the same.
Here's a pic of the parts.Not quite the same but will work.
The parts should be able to be changed with just hand tools and a pin punch.
Easy job if the motors off, a bit tougher if on the boat.
Someone suggested WD or any spray lube PB Blaster works great too.
