Guide to replacing impeller on a 5.7 EFI Mercruiser
      #1858263 - 14/05/2008 10:51

Hi peeps, need to do this, anyone know of a step by step online guide for it? I'm sure it's quite simple but wanted to check anything out that might enlighten me.

You have to disconnect the two hoses at the rear noting which is in and out, and then remove the pump by removing the two bolts which connect the bracket to the block, its easy when its on the bench, just make a note of where the bolts go as they are different lengths and some go right through the pump and bracket with nuts on them.

Depends if you have an Alpha leg or a Bravo. On the Alpha the impellor is in the leg as per outboard. The Bravo has conventional Jabsco driven off engine.

Hi, it's a Bravo 3. Thanks for the replies. Neil, there isn't a guide on that site for the Bravo 3/Engine based pump that I can see.

I can sell you a sedoc workshop manual for £20 incl p&p

it is the petrol mercs version and should contain what you are looking for and a whole lot more.
