A Hose of Surprise

[DeepFrz]

I was thinking that the hose looked like the clamp had been to tight and squashed the hose. Could have been the start of the trouble. However, looking at the Trident 100-250 hose it has much thicker walls and is a much more robust hose.

It is a high vibration location. Fixed to the hull and then a vibrating motor. Perfect setup for fatigue. Especially if it was a short run. Use the quality trident hose. Surprised that the hose was used for this application.

Very lucky indeed!!!

Nice save.

As a plus, the thick Trident type hoses are also a bit more fire resistant. If you lose an underwater hose to a small motor fire the boat's going to sink too.

That clear plastic stuff doesn't look like it would hold up to much heat for very long.

That hose looks to be severely over clamped. The wire is just to keep the hose from collapsing under a vacuum or neg pressure.
Looking at the pictures,... this is where the legal community fails the average sailor. The mantra of "double clamp everything" cannot be followed blindly, manufacturers and surveyors love to double clamp or tell you to do so..... without regard to whether the nipple has length enough to do so safely. That application is better with a single clamp of good quality.

Could that hose be to big for the pipe? My Volvo Penta has metric pipes that size up to 1 1/8, 1 3/8 and 1 5/8 hoses. Most marine stores only carry 1 1/4, 1 1/2 and 1 3/4. I had 1 guy tell me to just clamp it good, even though it was so loose, the pipe rattled in the hose.

Nope. Snug fit. Took a good amount of work to get it off.
