Split Raw Water to Thermostat Hose

[dkimball]

We were doing some footing on Saturday (long line and Boom) when on the last run of the day I was coming around the corner in my 2003 Nautique 216 when I noticed the change in exhaust noise. The kind of change that happens when it is being starved for water. Slowed to an idle and saw the temp gauge start to climb, popped to engine box to see water sprayed all over and standing pretty deep in the bilge. Then noticed the 3" split shown in the picture. Of course it is a formed hose and the local marina's didn't stock it. The good news is I was able to find a hose at Farm and Fleet that would work just fine while still providing the clearance as the formed hose. It did take some time getting the system to finally start drawing water again (ended up removing every fitting of the raw water system and blowing it out) but I think part of my reason was I was just letting it idle to prime it self which wasn't drawing any water, once I actually gave it some throttle it started drawing right away. I did order a new formed hose to have as a back up but the hose we put on seems to be doing the trick

Depending on how long it ran like that, may be worth checking impeller to be sure it looks good

Impeller is good. Changed it at beginning of season and checked it. It was still pulling water through impeller, it was just going into bilge.
