Are they used in Salt, or Fresh Water?

definitely salt water...



Cracks on the outside ( you'll see rust stains )

ah...very interesting...haven't seen anything like that. when i
changed the exhaust lines i checked the inside...they looked pretty
good but will watch

You didnt mention what the engine/drive setup is. I have no idea what
make of riser you're talking about. I was referring to mine, an
ancient OMC setup. In my manual, a test for air is to replace two of
the riser water output lines to check for air bubbles moving through
the lines when the engine is idling.
I imagine you're using something far newer than mine. But, as you can
see...Moosy just has to show its true colors, and pollute the thread,
without explanation of what its talking about. I'm no Mechanic, just a
driveway hero.I fix my own Boat, and it runs fine.

I would think that Risers used in Salt Water should be cleaned about
every 100 hours of steady use. If stationary, maybe every 150 hours.
Thats a guess, but Moosy will no doubt pollute us again with his idle
threats, and impish bull****.
