I purchased 2 of these kits, one for my 60hp 4 stroke bigfoot, and one for my freind's 60hp 4 stroke standard. Repaired mine first, kit is fine for that but in product description, it should clearly state "FACE SEAL SOLD SEPERATELY". The second issue I have is that this same kit is listed for the standard lower unit. Per my Mercury shop manual, this is incorrect. I still need to contact iboats in this reguard. The no face seal warning, and incorrect part# reference is what is dragging this review down, what I was able to install though was fine.
