Raw water pump impeller install
Going to install my raw water pump impeller tomorrow morning and need some tips and advice and I have a few questions. Boat is hour drive away and want to cover this before I leave..
08 moomba mobius lsv. Bought pre-owned, idk if the previous owner had the legs of the impeller installed correctly or not.(see pic) Screenshot_2016-01-02-09-28-26.jpg
Is this the correct direction of the legs? Is there only one way it will install? Looking at the illustration in the Johnson pump instructions and it is confusing. (See pic)1455419469654-776261328.jpg
My raw water pump doesn't look like the instructions 20151227_151959.jpg
Mine has a hose on bottom and top.
Hope this is clear, want to get this finished so I can get on the lake Tomorrow.
Thanks!Last edited by Leirhiht; 02-13-2016 at 11:13 PM.

Re: Raw water pump impeller install
You're fine, the impeller doesn't need to be installed in a particular direction, once you start the boat it'll work itself out.

Hardest part is getting the old one out. Lots of us use a locking needlenose or two paint can openers. I like to spray a little WD in there and bump the engine over a few times after I have the cover off. Be VERY careful reinstalling the small brass cover screws. Just crush in the little gasket a bit and quit. Do not overtighten.

I put a zip tie around the impeller and use that to pre-mend the vanes and then slide it into the pump and the zip tie will slide off the impeller. works pretty slick.
