just completed my 1st water pump impeller replacement on Alpha One Gen 2. Took the route of removing the lower while the upper was still attached to the boat. Removing lower and replacing impeller was pretty straightforward. However, putting the halves back together proved difficult. Part of the problem was getting the water tube lined up with the pump coupling. Finally got it together and tested it. No gear lube leaks, forward and reverse engage and water is exiting through the exhaust outlets so I’m confident the tubes lined up.
Knowing the sleeve is just a guide to make installation easier, I wasn’t too concerned at the time. Afterwards I got to thinking about the missing sleeve. What if it wasn’t missing before I started and fell off when I removed the lower and fell down into the chambers of the housing? My old quad ring fell into the rear chamber and I wasn’t concerned because that’s just the exhaust exit and that little ring should just pass through, right?
But what if the sleeve fell into the same cavity? Since I wasn’t the last one to do this job, I can’t be 100% certain it was there to begin with. Is this something to be concerned about?
