honda 135 service question

just bought a honda 135 with 150 hours on it. im not sure when it was last services, what does everyone suggest doing other than oil and filter change?

changed engine oil and filter, and changed oil in lower unit. they gave me some replacement seals for the plugs but they were white and flat, not like the o-rings that were on it. will these be ok? this is a very respected mechanic but i just want to be sure he didnt get something mixed up.

Don’t know about the washers/seals. But, id get a hold of an owners manual and check what Honda says about maintenance what and when.
