    Well, I really don’t think the lower unit seals need to be changed. The engine has never been used, so am guessing the fuel hoses are OK also. Just push/grab the hoses to see if they are flexible….I guess the fuel hoses should be changed if they are stiff and won’t move/wobble easily…
    Probably best to change the gear lube, at least check to make sure it is full.
    I don’t think you will have any impeller issues caused by just starting the engine, but it is best to replace the impeller in the near future….
