1997, 30 hp evinrude, long shaft.
This is a new to me motor, and I am new to the outboard motor world, fairly mechanically inclined and to make matters worse, I own a lot of tools.....
When I bought the boat and motor, I didn't want to hear it run (not that it would have) because it had old gas in the tank that did not have oil in it. It was being shown to me by a guy who didn't know much about it (the owner had passed away and he was helping the widow sell stuff). I could see oil dripping from the bottom end so I knew that would need some work. I bought the unit, fairly cheap.....
I cleaned the gas tank, cleaned and rebuilt the carb, replaced fuel pump, changed spark plugs and the motor ran fine. I did this work with the old leaky lower unit in place, while I was rebuilding another lower unit in my garage to replace this one. I put the rebuilt unit on, and no water....... After tinkering with it, taking it on and off many times to verify that I had things right, propeller turning right, key way in place, O rings in place and greased, nothing worked. I even took the old pump off the known working unit and it too, now, does not pump water. I checked the copper tube that goes from the pump to the motor, made sure it was in place top and bottom and is sealed correctly, and still can not get it to pump water.
The only issue that I am having, other than the no water thing, is the gasket that goes under the plate keeps falling apart. At first I though it was just because I had taking the pump apart a few times but after the second gasket, the first time I took the pump apart, the gasket was broke in half and falling apart from being wet. It was just mush in my fingers. These were not cheap pumps that I bought, they were purchased from reputable marine repair shops. Could the gasket be the issue? Im going to the auto parts store this morning to get some gasket material that may withstand water better and make my own, as I haven't seen a source for just the gasket, with shipping at a reasonable price.
As a side, I have the motor running in a tub of water, however I have tried the muffs without success as well. I have tried to put a small hose on the end of my garden hose, and while in the bucket, put the small hose right up into the water intake to force water to the propeller..... Nothing. I blew air in the pee tube, and into the copper tube feeding the motor...... Nothing....... I have reved the motor, thinking the faster the pump turns the more it would move water, nothing.....
after testing, I did notice that 2 of the plastic pump housings had some of the plastic melted right at the water intake of the metal propeller cup, Im guessing it's due to the cup getting hot? I have changed the plastic housings when I notice this, but I am on my last housing ( I have another one on order)
What am I missing? I have had this thing on and off the boat at least 15 times in the past 2 days, it's driving me nuts.
