I currently own a 2007 26' Rinker Captiva which only has 1 hole for the drain, plus bilge, and I used to own an old 17' fisher with 3 holes (live well inlet & outlet, and the main drain plug.) plus bilge.
However, i recently purchased a side project for this upcoming fall & winter. Pictured below is a 1991 Nitro 185TF. Currently no main motor, just using it on a small local pond for this year with trolling motor.
Took it out the other night and i stuck the drain plug in, sealed a few old screw holes the previous owner left from his gps transducer and hit the lake with my wife. 10 minutes in we find water coming in quickly and lots of it!! Luckily the bilge worked great and started shooting out like a fountain and Of course, the jokes were made about making sure the drain plug was in, which it was.
We get back to the trailer and yank the boat out, only to see water pouring out this 4th hole above the drain hole. Its perfectly centered between the inlet and outlet holes for the single livewell, and directly above the hull drain. Anyone know what the hell it goes too? I am pulling the batteries and what not out this weekend to verify all hoses and pumps are cracked or leaking. I have filled the livewell up and verified which is the drain hole (clearly inlet hole has black screen over it) and also made sure the recirculating pump works. I didnt have any water loss during that test. When we pulled the boat out, this hole looked like a hose was turned on as well as the bilge hole on the top driver side shooting out like a fountain. Lucky we didnt sink!!
I know i need to seal the outlets/inlet up a little more, i was just eager to get out and see what it was like!
ANY HELP WOULD BE GREATLY APPRECIATED!
