Help Please!

I have a 1982 Mariner 25 hp ser # 695-311253 that I had to replace the impeller and the pump housing on! I did this today and started the motor and there was still no water comming out of the tell tale! I took everything apart and checked it all again and the only problem that I can find is that one of the 3 bolts that hold the housing in place will not tighten! I was talking to a boat shop and told them what was going on and they said that the bolt not holding it tight is letting the housing lift and loosing the water there instead of pumping it up! Does this sound right? I am going for diffrent stainless steel bolts today! Just for the record if I put water directly in the water line it comes out of the tell tale nice and stron so I know there is no blockage and the lower end is clean also!
Thanks

Ok so I got the pump all nice and bolted on and am gonna put the motor back together today but I have thought about something that might be my problem so thought I would ask! The tub that I have been testing it in I just realized is too shallow to bring the water line up to the pump itself, it's prob about 2-3 inches below the pump level! Would the water not need to be above the pump for it to pump water? I have a set of muffs but have not tried them yet!

Re: Help Please!

Beave,

Go with the muffs and a garden hose. Set the faucet to give a modest leakage at the muffs before starting the engine. Never run above an idle throttle setting.

Using a bucket is risky. The water level has to be above the water intake grids and the prop has to be removed. You then have to keep filling the bucket or try to catch the peehole water.

Enjoy

Ok so I ran it on the muffs and got water pumping out the hole! It's running a bit rough so am gonna pick up some new plugs and a can of seafoam and put it in the water on Sat and see how it goes!
