Default Unknown holes in hull? Help?

Hi, brand new owner of an '98 1900XR...I see my boat has two holes in the port side hull about a 1/4 way back from the bow. Anyone know what these are or whether they are even supposed to be there? Looks like maybe there was some sort of fitting that might have broken off? Worried they are a good way to fill the hull with water :0

Thanks!

David

I’m not familiar with your model but I would think they are drains for 5he ski locker and an ice box. Yes you need to fix the missing thru hull.

There used to be nylon through hulls there. The nylon is not UV safe and they get brittle over time. The one on the left has broken completely off and is now just a hole in your hull. This would mean the thread stem and hose barb are still connected to the hose, however now they are discharging into the bilge.

The one on the right the external flange (mushroom) of the through hull has broken off, however the caulk is holding the threaded stem and the lock nut on the backside. This is good news, since that means the hose on the backside is more than likely also connected and discharging overboard.

These could be anything that needs to drain overboard: Bilge Pump discharge, locker drain discharge, cockpit sink, etc.

Determine the size and replace with Marelon. Bronze and stainless are more expensive options. stainless introduces some issues where when water is introduced to an oxygen deprived space, SS will rust. (Think screws and bolts in deck plates and stanchions).

Thanks all for the help. Turns out they were drain holes for the two ice box bins in the passenger side dashboard. Couldn't find any fittings that fit that diameter through hole so had to go a bit larger but replaced them this weekend with new tubing etc.

Hi.

I have the drain and a compartment under the MusiStation.


Does that mean I too have an Ice box bin?

That would be awesome!

If the lid doesn't seal and the box isn't insulated......it might not be an effective 'ice box'.
