How about revert to raw water cooling and deal with it when you get home?

That's plan B if this doesn't work. Don't really want to put salt water through this engine, as it's been FWC since the rebuild. Plus I'm not sure I have all the fittings I'd need.

I decided to go with epoxy, as I don't think I could get enough heat from a propane torch to solder on this heavy metal. If I was home with a maap torch I wouldn't hesitate.

Let you know how it works out tomorrow.

It wasn't that it it wouldn't hold, I just couldn't get the tape to cover the holes right up against the body while the HX was still in place.

The epoxy fix worked perfectly. We put in 5 1/2 hours before anchoring on the South Edisto River to wait out some T-storms. Only 7 1/2 more hrs to Charleston.

Meanwhile, a friend contacted me and offered a very attractive price on a new HX, including FedEx to Charleston. I accepted the offer, and will replace the HX when it gets there.

Well, the new HX arrived and is installed, but there were a couple of "gotcha"s along the way. Monitor has made some changes in their design in the 8 years since I installed my original HX:

1) The zinc location has changed from the bottom to the top, on the diametrically opposite side. In my case, this moved it from 100% accessible to a cramped and blind location. . But it's better positioned to protect the raw water barbs.

2) The coolant return fitting location has moved from the side of the header tank to the end. Fortunately my hose had enough slack to reach.

3) Both of the coolant fittings have changed from 3/8" NPT to 1/2" NPT! This caused me some grief as I had to hike all over Charleston looking for new elbow barb fittings. Never found them, but did find some adapter bushings that allowed me to use my original fittings.

Never a dull moment...

Well Ed, I guess you made your boat payment for this month, challenged your brain, and got some good cardio points too.

May you be less challenged for the remainder of the trip


Cheers,
Russ

Since Charleston, we've been making rapid progress north.

After leaving extra early to catch a favorable tide through the shoaling at Isle of Palms, this put us at a poor tide for transiting McClellenville. Thank goodness for the Navionix crowd-sourced sonar charts! I crept from one slightly deeper spot to another, and we made it through without touching bottom.

Since it was still early, we continued on all the way to Georgetown SC, anchoring for the night.

Next day, we went up through the beautiful Wacamaw River, some of the prettiest scenery on the ICW, and stopped at Osprey marina for a few days to visit friends. Osprey is a great place, and very inexpensive.

From Ospery, we did a long day (56 nm) to Southport to position ourselves for an early flood-tide current up the Cape Fear River.
The next day, our timing worked, and with wind & tide in our favor, we did 7.9 kts for a while! A second long day (56 nm again) got us to Mile Hammock, just outside of Camp Lejune. The military entertained us until midnight with repeated landing practice for both large helicopters and Osprey V22 tilt-rotors.

We had checked with Camp Lejune, and they were supposed to be closing the ICW from noon until 5 , so another early start to avoid that. But when we got there at 7:30 am, a Navy patrol boat stopped us and told us the ICW was "closed for live-fire exercise" until noon!! A four and a half hour delay!! We had to backtrack a bit and anchor, along with two other boats. And as soon as we got settled in to wait, the Navy called on the radio and announced that the exercise was canceled and we were free to go! Typical SNAFU. At least it only cost us an hour!

We finished a third long (51 nm) day with no further trouble, and are anchored in Adams Creek, just south of Oriental NC. We're going to visit some friends near here for a few days.
