Great replacement parts!
Perfect fit for my 2003 Mercury Salt Water 150 2 stroke engine. Everything I needed was in the box.” “Good quality parts and saved me a lot compared to OEM.

The must do service package. This is a "fits multiple" kit so youll have some extras. The kit also includes the lower unit gear oil seals, which is awesome. I always trust quicksilver to be durable and a great value for the money.
