Re: 2000 Mercury 150 Impeller
It might also be good to have a service manual handy. Sometimes you can pick one up on eBay for a good deal. As an example, I saw a Merc 115hp 4-stroke manual that normally sells on the Mercury website for $84.95 on eBay for $.99 + $4.05 s/h, so I bought it. Has an entire section on the lower unit, including replacing the impeller and water pump. -Ken
