Re: three brass screws

thank you to everyone who has helped me, and let me know promptly of how dumb i was for dry runs....

here are a few pics of the impeller and the housing, there was a small amount lubricant in the case, and the flex of the impeller seemed good to me. i cleaned it out a little and inspected further, looks good. i must be quite lucky:)

the reason i was not sucking up any water appears to be because the water
inlet was not fully submerged and could not build pressure.

i also found all the drain bolts and tightened them.
i looked inside the cooling area. the antifreeze looks very consintrated.
i heard some one mention i should run it with fresh water? any comments,
hot do you drain the antifreeze?

Re: three brass screws

I bet the antifreeze saved it, antifreeze is slicker than raw water and will stick around a little longer.

I use synthetic grease and line the inside of the pump housing very lightly when replacing them. DO NOT use oil based lube as it can attack the impeller material.

Make sure all vanes are absolutely intact. Then bend each one both ways to almost flat and look for cracks along where they meet the hub. If you see any cracks get a new one.

I run mine in a tub at times. You need to have the water deep enough to almost cover the plate just above the propeller. Also leave the hose running to ensure the level never drops, and also to keep from sucking in the same water and reheating it over and over. If the prop is still on do not put it into any gear as the spinning prop will blow the water out quickly, plus it could catch the hose and do some damage to itself. Mine takes a few seconds, maybe 20 or 30 if it had been completely drained, before it starts blowing water out the exhaust if it has been drained. There should be a large volume of water exiting the exhaust even at idle.
