2GMF Yanmar wp impeller question

First time replacing the impeller and gasket and I cant figure how to get the impeller out of the housing is it stuck or ? is it just the rubber or the brass collar also? Thanks in advance for your help . I know someone has had this happen to them.

The impeller is either on a spline shaft or is keyed.. and should slide up and off the shaft (rubber bit and a metal inner part that may not be totally visible, or have a rubber layer on it. There may also be a rubber disc that fits into the center of the impeller which will come off so you can see the shaft itself.

Protect the edge of the pump casing, and use two flat blade screwdrivers to "bite" into the rubber from opposite sides and try prying it up and out. Alternatively maybe try to grip the impeller hub with some slip joint piers and pull, depending on your access.

On my Yanmar 2GM20F it came off by gently prying with two small screwdrivers as Faster suggests.

You will tear it up getting it out. Be sure to lube the new one and the shaft well so it will be easer to remove next time.

That derelict boat was another dream for somebody else, don't let it be your nightmare and a waste of your life.

Just use a couple of pairs of needle nose pliers to grasp the impellor blades, one on either side of the hub, and tug gently. There is nothing holding it in except friction. The earlier suggestion to lube the shaft is wise so long as you do not use a petroleum based lubricant. (Some impellors don't like it.) Glycerin based or silicon based is prefered. You should also lube the inside faces of the pump before mounting the new impellor.

FWIW...

"It is not so much for its beauty that the sea makes a claim upon men's hearts, as for that subtle something, that quality of air, that emanation from the waves, that so wonderfully renews a weary spirit."

My marine dealer said to lube it with KY.
