This Parts Repair Kit for my 1995 Mariner 40HP Force outboard was very easy to install, after watching a repair guy video. Water pump works much better than before, as old impeller and the housing was worn out.

Never rebuilt a pump before, but it went well and works GREAT!

Wasted my money on a cheaper rebuild kit that ended up not even fitting. My advice to you is to spend the extra money and get this quality kit

I was hoping I could complete the entire water pump replacement with this kit. However, the grommet for the copper tube (pickup tube) does not come with it. So i need to buy it separately.
