I need to know if the 4 screws that hold the black peice in for the dive prop will let water into the electronics. I just got my sub back from nikko and they fixed it, I use this term loosely, they just needed to give me the right TX since they sent me the wrong one in the first place and said I needed to send the whole sub in to get it fixed. It looks as if they torn the sub down and put it back together. I found small cracks around the 4 screws on the bottom of the sub that hold part of the dive assembly and only one of the screws gets tight. They put some kind of sealant all around them, I think to get them to hold. I'm going to call them Monday and insist they replace the bottom Hull, which is mostly the whole sub.
Thanks, jjp
That's the dive motor propulsion seal. If the screw mounts in that area is compromised, no amount of sealant will keep the water out when you take that sub down for a dive. You can't glue that area as you will have to occasionally service the two electric motors for re-oiling. Use the associated motor bearing lube available at your L.H.S.
I'd say your sub's hull has to be replaced. I have a Nikko Ocean Explorer with a damaged hull. It's no longer capable of making dives due to damage similar to what you described. It's currently a surface vessel (just like an ordinary boat).
