Dave, good thinking!
Since the water came from behind (exhaust side), and you did not turn the engine, there was a good chance that you would be able to suck most of it the same way. However, I would not put too much faith in your impeller. If the impeller is good, the pump should prime from the cockpit (no need to pour any water into the hose). If it did not prime on its own, it means that it is not working properly. The impeller may look good, but it may slip on the shaft or the pulley (the v-belt) is slipping. I would be afraid that this may create some cooling problems. There is nothing you need to do for the winter, but I would think hard on addressing this before the next season. When you do your feed bucket method, do you have a shut off valve at the hose from the bucket to the engine? If you don’t, adding it helps a lot, as you can shut off the water (AF) feed from the cockpit and turn the engine off, when the water is pumped out of the hose. Btw. If you don’t like the idea of having any head of water in front of the water pump, you can try a method with a bucket on the ground and a hose leading from the bucket to the raw water intake throughhull. You can cut a thread on the inside of that throughhull and screw in a barbed nipple into it. The Good Old Boat Nov/Dec 2014 issue had an article on that. I have a scanned PDF if you are interested.

I was able to resolve the hydrolock with no apparent ill effect on the engine! It was quite an easy fix as well, didn't even need to mess with the injectors. Here's what I did, following a suggestion of someone on this thread: I disconnected the exhaust hose from the manifold and connected my shop vac to the header outlet. Then, with the vac running and all three decompression levers open, I turned the engine by hand a few times from the main pulley, then spun it a bit with the starter motor. After closing the decompression levers, reconnecting the exhaust and setting up my water feed bucket - this time in the aft cabin and NOT up in the cockpit - I went for ignition. It fired up more readily than I expected, and ran great with no new vibrations or noises. The raw water pump impeller was completely intact and looked like new. The oil was a little milky so I changed that twice, ran the motor for a while to get it up to temp, then finally winterized it from the bucket. Hooray for a lesson learned without injury or great expense. Thanks for all the advice guys! -Dave Sent from my T-Mobile Galaxy Note 2 -------------------------------------------------------------------------------- _______________________________________________ Email address: [email protected] To change your list preferences, including unsubscribing -- go to the bottom of page at: http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com
