If it shows corrosion on the outside then it is likely corroded all the way thru from the inside and will fail soon. Remove the elbow and give those corroded spots a firm whack with a hammer and they will probably collapse.

Re: More flow for cooling

Final report...

Elbow arrived... wrong part. Removed the old elbow cleaned it out... not serious muck... cleaned the hoses...again no muck to speak of.

Removed the hose from the sea cock and wiggled a screw driver in there until a good stream of water came out.... hmmmm was there some restriction there?

Fired up the engine and the flow is now fine.

I think it was a clogged seacock / strainer.

Thanks all!

Re: More flow for cooling

Why External Strainers are a Bad Idea 101 (Maine Sail) Why I Dislike Like External Strainers - SailboatOwners.com

Other than that, learn about your system. When we first bought our boat it overheated. So I took off the HX and found a lot of junk in the inlet port, like sailorchic said, pages ago.

Good luck.

Re: More flow for cooling

My temperature indication was ultimately my problem. I bought a handheld IR temperature gauge and it never went above 180 F. Gauge indicated 220! Now to fix the gauge.
