WESTERBEKE 7.6 Diesel Winterizing - Problem

Ok,

I don't recall ever having this issue....I closed the seacock and pulled the hose from the seacock and lowered into a 5 gal. bucket with 4 gal of antifreeze.

I drained the strainer and poured antifreeze in that too and closed it back up... Started the Geni and she ran fine, but she wasn't pulling from the bucket. I didn't have any issues that I recall with blockages. I shut her down and got another impeller...

I opened the waterpump and one vane on the impeller was broken so clearly it wasn't a bad impeller, but naturally I replaced it...

Then I opened the heat exchanger on the inboard side and checked for blockage. I ran a metal hangar down the tubes to make sure they were clear.

I took off the raw water hose between the pump and the strainer and the one between the pump and the heat exchanger. I blasted water from the hose through....no obstructions....

Resealed everything and restarted, and no water coming out exhaust...

Can the exhaust side be so blocked that it would obstruct all water? Anyone have this issue?

Edit:

Another note i forgot to add....

I ran the genie for a few seconds without the impeller in to make sure the pump was turning fine, and it is...

Are you sure the pump is turning. Bump the starter with the impeller cover off and make sure it turns.

Additionally is the hose between the strainer and the pump now drained dry? When I had a marginal impeller my pump wouldn't prime if there was any air in that line.

Sorry, I edited my post....I did check the pump turning...

I actually used dock water hose to run hose from the water pump side of the hose to the strainer with the hose still off the seacock... When I ran the water it flowed right through the strainer out the other side and just poured water into the bilge.....So, no blockage and for sure water in the line and strainer when I reattached the hose to the water pump...

I didn't reopen the seacock, or need to, because the hose is in the 5gal bucket. the end is at or near the bottom of 4 gal of antifreeze....

Perhaps it won't prime, but I don't recall having this problem before...I'm guessing a massive blockage on the exhaust side, but I'm having a hard time believing it. Because I would think it would still trickle out.

If the Impeller Has a keyway on the shaft make sure the key didn't slip off when you pushed the Impeller on! The shaft might be turning inside the Impeller

@Express 390 Thanks, but no, there is no keyway....It's a slot the bar fits in...straight forward and no way to get it wrong.

Then it might just be an airlock "Good Luck"
