Try to remove the seal, there should be a part# on it. you can borrow a puller for the balancer from just about any auto store. Drill a small hole in the seal and with a self tapping screw on a slide hammer the seal should come out.
Look closely at the lower seal surface of the driven gear. That is a problem area also. A speedy sleeve works good on that surface. Also the lower seal surface below the water pump. When I had my shop I always had a good stock of those sleeves.
To pressure test the upper housing get a small...
The Iwo Jima was anchored in DaNang with one of the 36’ whale boats being used to run people to the shore for various reasons.
I was an Engineman and my job that day was to assist in getting the boat back to the David. The coxswain started the engine and shifted to reverse, right at that time...
If your problem is “Bravoitis” the problem is not the water pump.
Add a sea suction through the bottom and merge it with the incoming water from the drive.
Go on the Donzi owners site and you will find that Bravoitis is pretty common.
That is a far cry from what “sea store” cigarettes sold for when I was in the Navy. 12 cents a pack. As soon as the ship left the 3 mile limit the line for them was unbelievable.
I was able to quit them in 66, I guess that is why I am still around today.
One time my mom had a squirrel in her attic. I bought a trap and caught it. I then took it for a ride and let it loose.
A friend later told me that I could have been arrested by the Wildlife cops for “trapping“ a squirrel. So what is the correct thing to do ? Shoot it in the attic?
Try to unscrew the fuel suction pipe out of the tank. There is a fine mesh screen in the tube that may be partially plugged. Pitch the screen, put it back together then take the boat for a ride. Make sure all the fuel connections are tight and leak free.
You do not need a high pressure fuel...
If you get a mercruiser pump just make sure the fitting threads are the same.
If your pump does not operate electrically you may just have a worn out set of brushes. They are not hard to replace and no special tools are needed, just patience. These are the same pumps used on OMC outboards.
Was there a spring with 2 washers under the center of the top cover? They could have gotten sideways when you installed the cover. If there are too many shims on the center post of the upper gear housing that could also cause a bind. I cannot think of any thing else that causes the problem you...
There is a “O” ring that goes around the outer perimeter of the water pump housing that is to aid in keeping exhaust gasses from entering the incoming cooling water. You may have put the plastic thrust washer upside down.
The large sealing ring that seals the lower section of the upper housing...
