Good ideas, or not?

[SC35]

I'm currently getting flamed elsewhere for suggesting that this might not have been the best idea.

The poster has bought a non-original pump with the wrong outlet size: the upper clamp is securing the silicone reducer to just the hose.

What could possibly go wrong?

OK as a "MacGyver" fix to get you home maybe, but I wouldn't want that as a permanent solution

To be honest it would probably be fine, it’s not exactly high pressure.

But if that’s what he thinks is acceptable god only knows what the rest of the boat must be like.

If it was wrong - why didn't' he just return it and get the correct one ??

The Perkins in my boat has quite a few reducing diameter hoses to connect one bit of plumbing to another, all are part of the original design, today I am going to replace the 90 degree reducing hose from the gearbox oil cooler to the bronze pipe that leads to the raw water pump it goes from 2" to 1 1/8" or aprox 50mm to 29mm. The hose is perished and collapses under the suck from the raw water pump.



Ordered 2 custom made silicone hoses for it yesterday at about 3pm, the hoses arrived today at 10:30

Is the green tube a hose? It looks like a copper tube to me.

Sleeve it

The inlet doesn't look good

I’m just getting used to the Irish expression “sure, it’ll be grand”.

I’ve got a few of these “insert and clamp tight” transitions in my fuel lines.

You work really fast !...I’m much slower

It looks like this is a modification from using a pump where the solid pipe connects to the water pump, to a water pump where a flexible hose connects. Follow the copper pipe round in a sort of anti clockwise way and you'll see a clamp holding it in place. It's not a modification because the outlet size is different size, it's because it's a completely different method of fitting which sounds worse but in fact is okay. The only thing that could be better is if the solid pipe was barbed (unless they've retrofitted something) to help secure the top (outlet) hose.
I think...

 

[colhel]

Another thought I had, it could be the original pump (with solid pipe fitting) is discontinued so to keep the engine going this is the only option.
Again, probably...

Interestingly, in most of these brass pumps....the impeller brass plate has some manufacturers engraving on them

 

[volvopaul]

Nothing much wrong there , looks like a 41A with a later type pump that is set up for rubber hoses . The early pump was metal pipes in and out .

 

[Bouba]

I agree, you only need metal pipes for going around bends...so rubber connector is fine...and the reduced diameter in the metal pipe probably isn’t much different than a rubber hose that is a little kinked from going around curves

Hmmm, you could be onto something there.
If the U-Shaped thing is a solid pipe, that that changes things somewhat.

 

[colhel]

Yes it is a solid pipe. It might just be long enough to butt up against the pump outlet. This pipe is fixed and is held very firmly. The small length of hose is just joining the pipe and pump outlet
