Hello,

I am going to attempt to replace my impeller by myself. I have an outboard 77 merc 1500 and did a search online at mercruiserparts. I have a few questions,

P.S. I don't have a manual and am yet to find one for my motor.

make sure when you take the old impeller off you dont loose the
key that lock it onto the drive shaft. i made this mistake the first time i dont it but lucky enough the key fell inside the gear casing and i was able to retrieve.

As a result the impeller wont spin so no water will be pumped. Other than that its pretty straught forward, few spanners and a socket set and you should be able to manage it.

mercuryman,u can get a manual from basspro,west marine or any reputable marine dealer in your area...two publishers are either clymer or sealock...lots of illustrations and diagrams to work with...gaskets are a must to replace,also take a hard look at the housings,,,depends just how "hot" it was ran..if the material looks melted on the outside it probably needs replacing///any questions u have i'm sure someone here can help ya....good luck
