I was told that I have a high performance lower unit by my mechanic and needed to use hi performance lube. I do have a low water pickup is all I know. Where would serial number on the lower unit be. I need new water pump, base, etc. Does anyone sell the whole kit (Including the base)? Am I better buying Merc. than Sierra?
