[C320-list] Simple Hose Replace? - Between sea water pump and heat exchanger (resend w/o images)

Howdy.

I have a Yanmar 3GM30F.

I found a slow drip coming off the hose leading out of the sea water pump.

It looks to be coming from near the clamp on to the hose. I could try to
tighten up the clamp, but I think it's probably best to replace also
replace the hose.

I'm guessing that since this particular hose is still flaking silver paint
that it probably was factory.

I've replaced other hose runs with Shields 250 5/8" hose.

I'd like to do the same here but I was curious about the big bend right
before it enters the heat exchanger.  Will shields 250 set and hold a bend
like that?

Any other advice on doing this well?

Best,
