Had this motor around a while, have a cabin up in the mountains in Norway, and real heavy fibergl*** boat, 2006 had a car accident hip replace, can't move this heavy boat down to the lake. Friend at work lives on a lake young family did not have a boat. Told him come and get it. 4.5 twin evinrude went with it. Had not started since 2006. He called me and said motor won't start, went down change plugs pored some gas in the spark plu hole, it jumped and started. Noticed that took a while for water to come out from cooling system and said we should change impeller. Tough to get the lower unit off but managed. no split in the shifter rod as I thought, some hits with a rubber mallet and it came off. changed impeller and put it back together, got it on the boat, started first pull, but no warer pissing out. I'm thinking 3 things, 1, put the plate on top of the impeller upside down, 2, impeller upside down or 3 did not get the key on the impeller slipped off before seating on the flat spot on the drive from the motor. Looking for some advice on doing this job, or a drawing of the ***embly for the water pump on this type. any help is appericiated.

It might be a good idea to try some heavy monofilament line up the tell tale hole while motor is running, maybe weed trimmer line. Its possible some bugs may have made a nest in that hole, so it might need some good shoving to see if anything comes out (save the string, may need to try again). If still nothing then go back through the water pump again.
Good luck.
