Can use PVC for my cooling water intake?
I am thinking about running sched 40 pvc pipe for a portion of my raw water intake line. I added an oil cooler and ended up with a custome plumbing situation. Is there any reason I can't hard pipe some of the intake line using PVC?

I bought the hardin marine combo cooller that is thermosat controlled. i had the same issues and i gave it a shot. the inlet would hold but the outlet would blow off. there is no raised edge to the endo fo a pvc elbow like the hose barbs that can be used. it also added length to the cooler and almost touched my risers. it blew off 3 times atttempting to get on plane.
So, learn from my mistake. take the $20 that would have gone to misc fittings and hose and spend $100 with Cp performance for the hardin marine fittings. have not had a single problem with them and they look great!.

You can get barbed Plastic fittings from McMaster-Carr which I ran for a while but had some issues with a cpl of them blowing off on the pressure side of the pump which would be the oil cooler side. I finally replaced them with SS barbed fittings from MC ..The problem was when the oil got it heated the water enough to soften and distort the fittings ...I still have a cpl of plastic fittings but the are before the cooler. also MC has the fittings in Aluminum or Stainless .....m

Find a local hydraulic supply house and go shopping. There are plenty of good hose products out there that will NOT put your engine or worse, your boat at risk. Most have a great selection of some pretty good looking hose and have SS fittings and elbows as needed.

Thanks for the advice guys. I'm not looking to skimp. I'm really looking for the best way to connect a line between two 1 1/4" hose nipples, and pvc seemed like the best alternative to a "molded hose".
Seems to me that regardless of wether I use PVC, copper, or stainless the weak link will be the connection to the cooler which will be 1 1/4" hose with a hose clamp.

I ran into the same thing on mine and I used stainless steel tubing I made up, it was easy and free since I work at a power plant I have access to a complete machine shop at work and I have even had the machinist custom make some outdrive parts.
