OK, Where's @swatski and @gmtech16450yz ?!??! I need someone to tell me I didn't just make a ginormous mess out of my pump housing.
Been fighting a cavitation problem under load when tubing. Might be technique on my part, but still bugs me. Put an L13 cone on a few weeks ago, lost some RPM, but still had the cavitation while turning/tubing. Read lots of talk of resealing the pump to keep cavitation at bay. So here's what I did about it.
Picked up some marine sealant. Finding 3M 5200 around here on a Saturday is like pulling teeth. Loctite has a comparable product, so I'm gonna give it a go:

Here are a couple before pictures. You can see a few places where there appears to be missing sealant, or maybe it has failed and been sucked out. Either way I can see where this is maybe not the greatest thing ever. boat has 48hrs on it I think, is just over a year old, and hasn't been touched inside the pump since it left the factory.
SO.....I got to work with the adhesive/sealant. I made a humongonamous mess. There is sealant on freaking everything. I wore latex gloves, but tore one. I think at one point I had multiple fingers adhered to each other. This is NOT something you should do on your back under the boat without good lighting. I pushed through and got the below results. Was really just trying to cover every seam that I could find with a good healthy coating of sealant. I smoothed what I could, but with only a finger to work with as a "smoothing device" it could've been done better I think.
Here's the results:
So there we go. Have I completely fubarred the pump? Is it not enough? it looks similar to what others have done, but this is the first time I've done it, so I suspect it's still not quite right. I'm anxiously awaiting some feedback from the experts. I'm headed out tomorrow with 4 adults and 2 kids. Should have plenty of time to tube and test so long as the rain holds off.
