pickup tube. . . . Am I the only one?
OK fellow Speedsters. He it goes, Ive got a 24 skater with 2.4 EFI Bridgeport's Offshore mids. I've owned the boat since 95. I have Sheared the water pickup tube in the mid twice now one on each motor. The last time was probably 3 years ago but maybe only ten hours or so of run time. Its 1/2 copper and it breaks clean about at the halfway point. No one I have talked to has ever heard of it happening and I know a lot of people in the performance boating industry. The first time it happened I chalked it up to a defect. But now I believe its a harmonics thing. Anyone else ever had this happen??

I've never seen it or heard of it happening . I suppose we could guess what it might be all day long ??? Is it breaking above or below where the exhaust exits the tuner pipe ? hf...

I’d try an elastomer on it. Some rubber hose heat shrinked around most of it. If you get a slightly too tight hose and split it and then using a quality heat shrink to wrap it down tight that will add strength and if it’s a vibration related issue that should cure it

I've broken on and split one down the seam on the old ridge back. I took some heater hose and pushed the tube through it leaving a few inches on either end. I've seen it on a couple big block Yamahas too.

I’m going to try blue copper pipe, it’s a thicker wall than the red which seems to be what mercury uses.good idea on heat shrinking around it, should absorb vibration. Luckily I monitor gauges and have caught it both times before I smoked a motor.
