Rubber engine mounts (replacement)

Do outboards have a specific replacement date for replacing rubber engine mounts? I'm not noticing any vibration (considering its a 2-stroke) but wondered if it's on the list of items to consider as part of a service?

Engine is 2006 M60C and pushes like an Amtrak locomotive at full steam. I need to replace the impeller this season anyway, so may consider engine rubber mounts, more as a preventative measure as the gearbox would be off. Any write-up or videos out there. How easy is it to do, etc.

I got a good deal on lower mounts so have 4 of these winging their way to me. Top mounts are a different part and look inaccessible.

If they go you will see a lot of movement when you accelerate or drop off the power.

Otherwise I would leave them be !
