1985 force and 86 Mercury running issues

I have two boats and two different motors but they both have the same issues.

I took them both out yesterday for the first time on water and was let down by both of them.

My force 85hp couldn't get going faster than probably 4-5 mph even though the engine sounds like it's running fine, there's absolutely no power.

Same issue with the Mercury but I may have achieved roughly 5-7 mph with that boat.

Any advice or tips are very much appreciated!
 
If they both run and rev up but don't move??
Then the prop hubs have probably spun.
There's a rubber hub that was pressed in under great pressure.
Over time and use the hub can spin or let loose.

Most anyplace that has anything to do with marine will have a prop repair company that they
can send your props off to for repair.

They sell props on here.
