Copper or not?

[jaybird56]

i am changing from short shaft to long shaft and water tube broke do you really need copper tube or can you use alum.? will it make a difference which type is used?

Re: Copper or not?

Are you replacing the tube, I think a new one is made of copper.
If you are trying to patch it up, how are you going to attach a copper tube to an aluminium?

will connect them with a 3/8s rubber gas line and clamps, already put it together and checked water flow is good, will test on river next week, might just be a temp fix . what yall think use copper or if works this way leave it??

If it was my mtr I wouldn't feel good about it. Get a new tube and install it. JMHO.

Use copper. You don't see aluminum pipe in house water systems for a reason.

I agree with metriccrescentwrench & boobie, get the correct part and install. Peace of mind.

If you are going to even be close to saltwater, the aluminum will disintergrate.

Re: Copper or not?

why is the water line copper ? most of the rest of the motor is aluminum. does anyone know?

Copper doesn't usually corrode.
Aluminum is cheaper and easy to mill.
Handles heat real well too.

thanks jerryjerry05 i didnt think about the heat,, it is close to the exhaust at the place i joined together but i dont think it gets very hot and has water all around it when in use. still plane on testing it in river this weekend and next water pump change i will go back to copper

The aluminum will last a long time.
I saw a guy fix his broken tube with just a piece of hose stuck over the tube.
Worked for over 10 years.
Saw PVC pipe in there too.
Lot's of jury riggin going on.
