I've got this problem fixed but wanted input and/or to suggest what I did.<br />1986 19' Bayliner capri, AQ-131 and 275 outdrive.<br /><br />On the AQ-131 is a pipe coming off the left rear (facing the back of the boat) of the heat exchanger.......<br />The pipe carries the sea-water through the exhaust manifold.<br /><br />Anyway where it connects on the heat exchanger is a piece of plastic and the tube just goes up into the plastic and has a seal on a lip on the tube. No bolts, nothing! pressure keeps it in there, and being bolted onto the exhaust 18" back, and one bracket with strap.<br /><br />Anyway I was spraying water out of there after replacing my battery/alternator and after sitting all winter.......scary.<br /><br />Anyway turns out I can SEE the seal, so it's not obviously working.<br /><br />I took it out and put it back in twice today, no easy feat considering you have to use a mirror to get under the manifold and line up the socket with the two tiny bolts holding the pipe in (and the bracket)......<br /><br />Seems my pipe may have bent from the cold/warm weather?<br /><br />The final fix was putting a chunk of 2x4 under the pipe and tapping it with a hammer until it straightened back into the hole.<br /><br />No more leak, temp is good, just a weird fix......<br /><br />Anyone seen this before?<br /><br />Needless to say the boat is ready for it's first run of the year tomorrow and has one super clean sea-water pipe!<br /><br />The nice thing about to day is that I found and cleaned ALL plugs that will be removed next fall when I winterize this boat......
