Where should raw water be pumped out of an alpha gen II?

[nben]

Haven't had one apart since last year so I cannot remember exactly where the water should and should not come out. I will offer this advise though........the housing is hollow and does allow some "blow by" while under hose pressure. I do remeber mine running water from the side drain hole while on the muffs and I think I remember water coming up from around the shift linkage like where your video shows. You just had your apart so you would have a better idea where the hollow void would and would not allow water to flow if it were under some pressure. Also, remember that when in the water at idle, the entire areas mentioned are under water so one would not normally see this.

p.s I won't have my boat out of storage for a few weeks yet, otherwise I would be happy to verify for you.

Thanks, I went back through pictures when I took the drive apart to do the impeller change and found that there is a big casted area where that water is coming out of. Since it's warm water, it must be routed there on purpose somehow. Here is a pic (green arrow points to the area the water is in, red is where the water comes out)

Just seeing this post in 2019 what was your out come of this problem I just replaced my sea pump on my alpha one gen 2 outdrive and seeing the same thing when running it on the muffs
