This is the only picture I have; we were actually taking a picture of the oil pump belts. This picture doesn't give you a very good perspective of how nice the tubing looks. I can take additional pictures on July 13 if are want more. You can just see the SS tubing line at the crossover on the port side.
As you have to maneuver around numerous obstacles, you can get an idea of the bends required; some are very slight. I am surprized that Mercury Racing doesn't run there water lines in SS tubing as these with a lot of units these could be made with a CNC bender.
Now a really hate the look of my braided lines!

Looks great !!

BenPerfected ,Thanks for the picture ....Sanitary !!

I have just used a condute bender.

If you want the bends to not have wrinkles, try filling them with bismuth and then bend. Bismuth can be found at some industrial supply stores. Be careful which bismuth you purchase. Some of the bismuth alloys are super expensive per pound. Buy the cheap stuff that melts at a low temp. Fill the pipe and let cool. Bend and then melt out the bismuth.

Reed , Would you mind expounding on the procedure ?

I'm guessing Bismuth is intended to be used in conjunction with heat . Also , the question of potential flaking scale . Scale may be acceptable for water ,subject to flake size .

Thanks for your contribution to the question .

Is Bismuth the lead looking stuff they use at Stellings between the inner and outer pipes?
