91 mercruiser alpha one gen II sterndrive

[lime4x4]

What should all be done to this drive unit?As far as we know nothing has been down to it except oil change.I replaced the exhaust bellow and the impellor.This winter is it a good idea to tear the whole drive apart and check everything and replaced all the seals or is it best to just leave it alone.The drive currently works perfect

No reason to pull it all apart if it's not leaking or making noises. But it would be a good idea to replace the raw water pump impeller after about 3 years.
