Es-Kape pump with a few hours on it. There was hardly any water in cone area, it was all in front of the rear bearing, so this points to the front seal as the point of entry. Think about this for a second though, for water to come in and make it in between the bearings, it has to go past the bearing seals front and back to get there. "Sealed bearings" are not as sealed as one might think. The bearings both had water in them.

Here is a bonus video. Everyone should go through their boat and check to make sure ALL fasteners are tight. I found several loose on this Es-Kape, and imagine what a fire would do in a plastic boat!!  >:(

I guess loose bolts on the motor are not the only issue :-[    Electrical connections doily noted.  Will check before next run.

I wonder how many guys don't ware life jackets, or don't have a fire extinguisher ;D

Yup, check everything... ;)

I carry fire extinguisher in each boat, as well as a life jacket. But I don't wear it here on the river. If I was on the ocean under different conditions, I would wear it then. But not on the river. Here, the only time it's required that you wear one is if you are operating a Jet Ski.

In my case, where I'm on open lake with a lot of speeders in boats plus I don't swim very fast ;D, a jacket and some flares are essential. \./8
In your case, based on the pictures of the your river, if you should happen to eject from your boat, you have more things in the water to worry about other than drowning :D, god forbid :)

Tom have you thought about using ceramic bearings for longer wear and less FRICTION?  and yes after replacing the ones in my kx21 I already know that they are MORE expensive.

The thought crossed my mind years ago, but it's a major overkill and there really is no need to spend the $$ on all that. My oil conversion and design upgrades have worked fine, and let the stock bearings last indefinitely.

Maybe Mokaiís cyber security well pick up on the solvent test idea and help them improve their quality control and testing.   :)

LOL I doubt it. Since the stock design uses two sealed bearings they would argue that the porous casting isn't an issue. The first time I had a pump going out, I popped the cone off and added some oil to get me by, had to drain the water out first. Louis at Mokai asked me if there was any water, and told me it was normal to see some in there... LOL 6 months later his rebuild failed and that's when I started this journey to pump perfection.  :D
