Exhaust Elbow Repair

No Comments 12 January 2012

Even products that look absolutely flawless can can occasionally have problems. Right before Christmas I was stretched out in the lazarette attending to a little detail that I wanted to tidy up.  A wire going to the starboard courtesy light was wound around a hydraulic line.  It didn’t bother anything, but without much effort it could be untangled and everything would look much neater.  I had to get my 2XL self into the far corner and reach up under the new stainless steel exhaust elbow to begin.  My sleeve got a little wet; that didn’t seem right.  A little drip seemed to be forming on the underside of the exhaust elbow and one of the welds was not perfectly smooth.  There was a rusty little spot on one of the new ribs that hold the water tank platform.

I didn’t relish the unanticipated job of removing the elbow.  The exhaust hoses are short and stiff and not very forgiving or flexible.   So everything got put on hold until the New Year arrived.  The starboard exhaust elbow came off  easier than expected, but when the exhaust elbow gets removed all the water that is in the muffler spills into the bilge……and I had it so dang clean, too.   Just so you know:  a muffler that looks like it might hold 5 gallons of water spills about 10 gallons of water into the bilge.  Trust me.

National Marine Exhaust was excellent.  Scott built the elbow about 18 months ago.  He polished the weld with a wire wheel and it looked fine, but when he put the torch to it , a big crevasse opened up.  So it got rewelded (extra-beefy) and we added a bonding tab for good measure.

Reinstallation was a joy.  There are not many places to get leverage or to pry against.  But with help from Mark Hanger of Mark’s Marine Repair the elbow finally gave  up and slid into place.  Usually it’s “two steps forward and one step back”; this was probably “one step forward and two steps back”.  But it emphasizes the value of doing business with good local folks who treat ya right, long after the check has cleared.

Water Tank Project – Phase 5……progress report

Comments Off 15 August 2011

It’s been far too long since I’ve posted on Velkommen’s lengthy water tank replacement project.  The project grew, like most boat projects, to be much larger than first imagined.  Better to get it right than do it twice.

We are looking forward at the port-side space between the hull and the aft deck, approx. 9′ x 9′ x 2′.  The third coat of primer is dry and ready to be painted over.  On the left is the muffler, temporarily supported by a 1″ x 4″.  The black hoses are for the hydraulic steering and coolant routed through the Hurricane Heater.  The lines coming out of the hole in the engine room bulkhead run to the remote Sea Freeze compressor mounted high and center on a shelf bent from 1/4″ aluminum plate.  It is partly visible on the right edge.  Adjacent to the compressor, also partly visible, is the one of the new SS exhaust elbows.  The replacement of this particular elbow began the renovations and alterations that you see.

All images enlarge with a click.

The second pic shows the first fitting of the Hurricane heater platform and the battery platform.  The starboard side is actually farther along; the painting is complete and the water tank platform and the battery platform have been installed.  Besides the battery cables, the water tank fill hoses are wrapped around the red bucket, and then there is the green bonding wire,  held up out of the paint by vise grip clamps.

Pic number three shows the first coat of Kirby’s #25 Light Gray gloss coat while it is still nice and fresh.  Three coats of primer and three coats of gloss.  That’s the treatment.  Thankfully, Kirby’s paint does not require special application proceedures. In this case a 4″ nappy-headed roller works pretty well.

No, I’m not going to paint the overhead.  Sure, it would be a nice touch, but enough is enough.  I’m looking toward ending this project not augmenting it.

BIG Thanks to Ray Robinson (Robinson Woodworking) and Mark Hanger (Mark’s Marine Repair) whose encouragement and advise have been invaluable.  And also to Travis Hanson (Hanson’s Marine Services) who matched the gelcoat around the locker doors.


On the Hard – for a few days

2 Comments 25 January 2011

Right before Thanksgiving, I asked Jim Gardner at Bottom Time Diving to check the status of Velkommen’s zincs and bottom paint.   He wasn’t feeling well so he asked one of his dive buddies to take a look.  The report was not good.  Bottom paint in great shape but the props and rudders looked very weird.  It didn’t really look like electrolysis, but he had no other explanation.  That really left no choice but to put Velkommen on the hard the sooner the better.  The problem was that between work and holidays I just couldn’t find the time to get it done promply.  I called Jeff Harman at OceanAire Yachts for his input since he had applied the epoxy barrier coat along with new Sherwin Williams bottom paint and a Petit 6006 Prop Coat on the props and rudders last spring.  He said he was not happy with Petit Prop Coat 6006 and no longer used it. On January 14th she came out of the water at Cap Sante Marine for a good examination.  I’ve heard that pictures say a thousand words, so to avoid being overly verbose:

Bottom paint: wonderful!
Bottom paint over the new chine mods: double wonderful!!
Props and rudders: Too strange?!?!

The Petit Propcoat 6006 coating had failed. Less than a year ago, when it was applied it was clear and rubbery, about 1/4″ thick. What was left was thin, splotchy and adhesive-like. Rather like the residue that is left if you tear the flap off a sealed envelope. The good news is that the residue came off easily with a little elbow grease and sandpaper. As a precaution, however, we removed the trim tabs and rebedded them with plenty of 3M 5200 and new stainless steel screws plus new stainless steel bolts for bonding wire attachment. The transom zinc was removed and new 3/8″ stainless steel studs installed and locked down to the bonding wires. Even though no evidence of electrolysis was found, we attacked the problem as though it had. After all, it’s a boat…..better to be safe than sorry. We even installed a ProMariner Galvanic Isolator. the final step was to apply Petit Zinc Coat Barnacle Barrier 1792.  January 18th Velkommen is back in the water.  There was an eagle perched on a nearby sailboat mast all morning.  As Velkommen rode the travel-lift toward the water he finally took flight.  It must be a good omen for a high-flyin’ boating season right around the corner.

Guess what I discovered when I stopped at the Petit Paint booth at the Great 2011 Seattle Boat Show? Petit has discontinued Prop Coat 6006 and recommends Zinc Coat Barnacle Barrier 1792, instead. Right on!  BIG Thanks to Mark Hanger of Mark’s Marine Repair and Ray Robinson of Robinson Woodworking for ensuring that all the details got done expediently and perfectly.  Attention to detail is such a blessing in the salt water environment.

Cap Sante Marine did the heavy lifting and found space in their yard while the projects were completed.  The service manager, John James, runs a tight ship.


Water Tank Replacement and a Few Other Things – Phase 2

No Comments 16 June 2010

After examining all the possibilities for a little water getting into the lazarette, it finally came down to the fiberglass exhaust elbow on the port engine.  It seems to have deformed just a bit from age and heat.  It was not obvious at idle but showed up when the engine was at higher rpm.  Credit for the detective work should go to Mark Hanger of Mark’s Marine Repair and Scott of National Marine Exhaust.  The pad beneath the dripless shaft seal of the port engine showed more staining than the starboard side.  Scott picked up this detail right away and focused on the exhaust elbow above.  Where the exhaust elbow penetrates the bulkhead, there was  a gray/black stain down the aft side of the bulkhead.  Mark spotted it.   The problem elbow and the stain are visible in the pic in the  “Phase 1″ post.  Another clue I should have spotted was the black bathtub-ring stain around the bottom edges of the stringers where the water mixed with exhaust would pool until caried away by the bilge pump.

New exhaust elbows were ordered up from National Marine Exhaust; they are quick and the workmanship is flawless.  As is evident in the pic, the elbows are really beefy; impossible for an aggressively tightened hose clamp to do damage.  I found a tank size from Ronco Plastics that would go through the hatch and provide plenty of capacity.  The only catch is that I have to use two 30 gallon tanks on each side and plumb them together.  I made a mock up and it appears that everything will fit, maximizing storage space and water capacity, while improving access to all systems dramatically.
