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.

Subject: Stus-List Hydrolocked!

Good news!

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
