Not yet; been a little cold as of late. Ive sealed around the main bearing, but was not able to remove the grease fitting as the dang thing seemed welded on with how hard it was to turn off. Im going to try my best to fill it using a syringe to not overpack it, but I've gotta think air escaping...

10/4. I plan to use marine grease through a syringe as to not overcompress is.

Oh, word. I think my plan of action will be to put grease into that bearing, see if I can find a leak, and go from there. Thank you very much for your help, super helpful.

Yes I did see that! I looked through the post but mine visually looks alright. Im really hoping I don't have to pull that engine forward, as that's probably a ton of work to do.

Yeah, ill probably do that. Thank you for the name of it, I was having a hard time finding the name. I will do that and see if there's any improvement, as it looks like there is a spring-loaded ball acting as a valve. Again not sure this would be causing cavitation, but with how many items I've...

okay, so I did this and there's no cracks. What about this theory; I've noticed a little bit of water in the hull when I'm underway. obviously the vacuum bulge pulls out it so I never notice it. But, could that midshaft bearing be allowing air to leak past when a large pressure differential is...

Thats a good thought, but its not on low rpm. its actually maxing out its rpm. I've been thinking; could the seal between the engine and the impeller shaft be letting air in?

Pump seal? If thats the pump shoe then it should be. There was a felt strip that ran the length of the pump shoe, which I removed and replaced with a hefty line of silicone. All underside parts were siliconed.

If im honest, i do not know. But on the stock impeller/wear ring it was doing the same thing. That was why I replaced them but to no avail.
