I found a gentlman who had 2 oil coolers that were only used in fresh water. I should have them by Friday. That will give me all weekend to get those 5 rusty round 12 point bolts out of the broken one. At least I did the stbd (have to be outboard to get at it) a few years ago when I was more limber. Those bolts are now stainless steel socket head cap screws.
Here is a picture of my new/used units already with UPS.
By the way Paul, have you seen our friend Martina Mcbride in concert on PBS? Awsome.
Regards,
George
