First time underway in months!

Made Sister’s Creek today. I thought there was shore power here (for A/C). But not. Oh well. Generator is doing the job. Everything worked.
.

First time putting some miles on our spare (3-blade) prop. It has some vibration, but otherwise it performed about the same for speed+RPM as the main prop does.

Spare prop:
1” larger radius & slightly more pitch.
Our main prop, all trued up.

Barnicle Buster

I thought I solved the forward A/C unit’s problem yesterday by reverse flushing fresh water thru it and cleaning out the strainer. It worked fine yesterday after that. But the circuit breakers tripped twice this morning indicating the problem was still with us!?!?

Time for a Barnicle Buster flush!

I ran a gallon of this stuff through a “closed loop” for about 90 minutes. Followed by two flushes with fresh water.

Hopefully this keeps us going this time! If not, a new unit is in order, about $2500.

12k BTU.

Two 5/8” hose connections.
5 gallon bucket w/ pump re-circulating Barnicle Buster through the A/C unit in a closed loop.
Obviously, Barnicle Buster found some crud inside there!
The fwd A/C unit is under some storage, under the bed in the main stateroom. Fairly accessible!

Professional Detailers Aboard Today

Happy to have Brad’s crew aboard the boat today, (and probably tomorrow), for a first class cleaning and waxing job!

Spotless sun deck. Tomorrow: WAX!
Nothing like a professional detailing job!

Day Two

Team: Ian, Bryce, & Brooks

These “animals” showed up for day two at 7:20am.

After yesterday afternoon’s torrents, they said they’d be back to finish today. They were nonetheless pleased with how much they got done before the rain.

Everyone on this “C-Dock” is asking them for a business card, and telling me how impressed they are.

Ian buffing the starboard side from waterline to rub rail.
Bryce buffing every square inch of the rear deck area!
Brooks, a fellow Maine-iac like Ray, working the starboard side with Ian.

Hydraulic Steering Win!

I lucked out and found this first (easily accessible) gasket was crimped or kinked upon installation (probably 25 years ago). Actually, this may have been a mistake at the Teleflex factory where the ram was made.

Kink in moulded O-Ring.

The hydraulic steering system has had a slow “drip” since we purchased the boat 5 years ago. +/- 1 ounce of fluid was added at the upper helm every 2-4 weeks when underway.

Item #6 is the one I was able to easily replace.
Business end of the ram, reassembled with a new moulded O-Ring from the manufacturer’s re-seal kit.

NO DRIPS!

Reseal Kit # HS5183 for the HC5319 ram.

Replacing this cylinder/ram or removing it to service it, would have been a major project because the nuts backing the four mounting bolts were blocked by both a fore/aft stringer and the starboard fresh water tank.

Being able to find the problem and solve it so easily was serendipitous fer sure!

Dometic is the new manufacturer of this ram.
Part # is the same. The new ones are made of aluminum, not brass. ((Never use the old brass fittings on a new aluminum cylinder! Nasty galvanic corrosion will result.))

I am so glad I did not have to buy a new ram.

One of my former & favorite Long Island NY marine parts vendors shipped me the Dometic Seal Kit from stock! Lighthouse Marine Supply, aka https://marineengineparts.com

Above: The yellow arrow shows the mounting bolts whose nuts are virtually inaccessible on the Mainship 390. Cutting a big access hole would be needed in the 3/4” plywood to get a wrench under there. This plywood platform is in very close proximity to the bottom of the hull.

Here is a pic of a new brass ram before Dometic/SeaStar changed to aluminum construction.

Next Day:
Still no drips in the dishpan below!
All indicators point to a successful repair / maintenance project … which (DIY + Divine Providence) probably saved $2000 in parts and labor costs.
