[QUOTE="Ride_Klein, post: 232447, member: 6976"] Got the pump removed tonight so I could seal the area I think was leaking so badly. While pulling it I wonder if I didn't also find a reason for the cavitation. The top of the area where the pump housing seals up against the pump shoe appears to not have sealed. I can't say for sure, but hopefully a more liberal coat of silicone will help if that was a problem. More on the cavitation later. Onto the leak. [ATTACH type="full" alt="JSJB - Rideplate leak.jpg"]30982._xfImport[/ATTACH] This picture shows the area where the rideplate (black) meets up with the fiberglass hull. This wasn't sealed before so I added the bead of 5200. There was a lot of debris in there so I blew it out with compressed air then used qtips and carb cleaner to try and remove any residual oil. Back to the cavitation. [ATTACH type="full" alt="JSJB - Tunnel intake - Stern view.jpg"]30983._xfImport[/ATTACH] You can see the small lip at the leading edge of the intake tunnel where the fiberglass tunnel meets the aluminum hull. I'm going to try and smooth this area out between the aluminum hull and the inset area where the intake grate mounts to the tunnel. Toying with using Bondo-glass to smooth the area out https://www.jamestowndistributors.com/userportal/show_product.do?pid=6102 I've read good things about it, but wondered if anybody on tinboats had first hand experience with it?
