Your tutorial is the most helpful on KZitem for overhauling the Atomic 4 water pump. Please have all the tools you need before recording. While you are one handsome devil, please focus the camera on the job at hand. The neoprene seals have their backs (flat side) facing each other and the cup or U shape sides face one toward the impeller end and the other face the oil pan end. (The fluids then under pressure force the flanges of the seals to grip the shaft and the casting thus preventing fluid leaking out the weep hole). Your checking the internet before installation is a very good move. Thanks for a good lesson.

CAUTION!!: The second seal CAN NOT be pressed down passed the "weep" hole or else you'll lose all your oil, which I think he does in the video. It has to stay above weep hole of crankcase side of pump so install carefully and stay clear of weep hole. First seal keeps water in from impeller, second seal keeps the oil in the crank case. And numbers face up on first seal, face down on second. Numbers facing numbers. Otherwise, helpful vid.

I believe he noted the gap and the weep hole, but good looking out. I'm about to do this today and I'll keep that in mind.

Thanks for the helpful video. I'm about to rebuild my 202M-7 and this video here is going to be my guide (and gave me the confidence to take it on). I'll post back and let you know how it goes. Thanks again!

Nicely done. I have a recently aquired Atomic 4 and its good to know that the water pump is so simple. Great video!

Thanks for the specs on the seals - going to try and find them locally.

I was able to order the lip seals gaskets from Graingers with the dimensions you provided.

Thanks. I have a question for you. I assume the Atomic 4 has sacrificial anode zinc. Do you know what it requires? Thanks.

I would be interested if this pump actually worked well when installed. The shaft looked scored to me and it seems that it would prematurely fail.

why does it take so little to "score" this shaft? Anybody else tired of this water pump yet?

When I took the seals out of my pump, there were two little circular springs in there as well. Do those stay in there, or should they be replace as well?

Thise springs were probably parts of the seal.

Thanks for this video; I'm retired and thinking about buying a boat with an Atomic 4. Also, what site did you check to see which direction the new seals would face?

MOYER MARINE had something showing the direction, plus for the seals to work they had to be in the way I put them in. pump is working great. thanks for watching

Glad to see the shafts on those aren't pressed in. I thought they were. Most of those pumps came with grease cups on that 1/4" pipe that you just tighten down here and there to freshen the grease on the bushings. I think rigging a grease pump to them is over kill. Just tighten down a bit on the grease cup every oil change and you should be good to go. Please man, a grease pump in reach of the cockpit? What the hell sort of snipe needs that really? IF the grease cup is that hard to reach just pipe it out to a place it can be easily reached in the engine compartment and load up the piping with grease using the grease cup assembly. One less grease pump is one less grease pump to break. The rebuild kits include a new shaft sintered bronze bushing and snap ring too. Still though, 50 dollars total for two 4 dollar and forty nine cent seals is right up the transom pricing.
