Merc 60 pumping air blowing bubbles

Dexta · Aug 30, 2010

As subject says, I have a Merc 60. Six horse twin '61 + - ser# 1433859.

Changed out the impeller and still can't get it to pump water out the pee hole. In fact it's blowing air, most likely exhaust out the hole and down at the lower unit seam. Did I miss something putting it back together? Is there an exhaust gasket required at the attachment of the lower unit or is something blown up on top.

Your help would be appreciated. In addition would anyone know where I could get parts needed for this?

Oh woe is me. Everybody must've gone boating but me. I tried doing some searches about my problem and found that it might be in the exhaust cover plate area. Can anyone confirm this? Is there also a seal down at the lower unit juncture?

I've had a problem with a small outboard like that before and all it turned out to be was my test tank wasn't deep enough and wouldn't allow it the volume of water it needed to pump. I doubt just changing the impeller would cause your exhaust seals to go out. Hope that helps.

Hey, thanks for the reply, hard to come by on this site. Looking again at my setup it may be a tad low on the water side. I'll give it a try.

Winged Wheel, you did it. I'm so glad I didn't break down that exhaust plate. Brought the water level up to where it should be and it seems to be pumping great now.

Guess that's why some of us are here, it's great to be to be an armchair mechanic, share your knowledge and expeience with others and guide them toward sucess. And best of all... you don't get your hands dirty!
