Finally….A New Country!

We decided to stay an extra day in Mayaguana to get some rest as well as enjoy the spearfishing offered on the island.  Initially, we had planned to leave that night after a couple of hours of sleep and continue on to the Turks & Caicos, but after seeing the water quality (we dropped a quarter in 35 ft of water and were able to see it on the bottom from deck level), we couldn't resist exploring the reefs.  As well, our buddy boat, Sailboat Furminger has been having a bunch of mechanical problems lately, the most recent two being setting the engine room on fire while underway from Long Island to Crooked (a wire had shorted out and ignited their oil absorbent rag under the engine…see their site for more details), along with losing their throttle control cable also while underway from Crooked to Mayaguana, the day after the fire.  What had happened with the cable was that they had paid a marina back in Baltimore $4K for someone to install new control cables and a dual action control arm as their binnacle mounted controls had broken at that point.  Since they are new to the whole boating arena, they didn't notice that the mechanic had improperly routed the morse cables so that the throttle cable was sitting against their exhaust riser, which ended up melting and seizing the cable (you can't trust anyone!).  When Nico went to throttle back, he broke the control arm as well.  After they finally got anchored up later that evening, Frank was able to go over and jerry rig a simple system for them consisting of lines and pulleys so that they could again control their throttle from the helm.  The sea always manages to find the weaknesses in any system so it pays to be handy...

After a good night's rest, we spent the next morning hunting in some of the clearest waters we've seen so far.  Of course, the day's haul was stupendous, and we were able to spear some Slipper lobsters to boot.  Frank and I have been looking for these elusive Slippers now for many, many years (at this point, I'd say close to 10).  Ever since we've heard about these things, we have been hoping to spot one.  This time around, not only did we finally see them but we managed to catch 4, and they were absolutely delicious.  They are a lot like Spiny lobster in flavor and texture except a little sweeter.  They however don't hide in the same way Spiny lobsters do.  Normally when in search of Spiny lobster, we look under a rock or coral head, and they are usually just tucked up under there, sitting up, just staring at you, antennas waving around just waiting to be captured.  With Slipper lobsters we found that they usually cling on to the undersides of the rock/coral in a nook very well camouflaged, so when you're peaking into a hole, instead of looking down, you would look up and along the sides of the walls.  Though hunting them was slightly different than hunting Spiny lobster, preparing them was just as easy.  We simply steamed them and dipped it in melted butter.  In the same meal, we also prepared Stone crab, which were also just as delectable.  It was a real treat as crabs tend to be a little more rare.  I now know why they call them Stone crabs, as the shells on them are rock hard.  I lost one in a reef trying to spear it, with no luck as my spear wasn't strong enough to puncture the tough shell, and all it did was deflect off before the little critter ran away.  How frustrating!  Frank, with the better spear and skills, managed to spear one that Nico had spotted right between the eyes (as you can see from the photo). All in all, our brief stay in Mayaguana turned out to be very worthwhile, and I wish that our weather window wasn't so short so that we could've had more time to spend exploring this beautiful, remote island.  

They really look like slippers!
I love Mayaguana!!!
This poor crab didn't know what was coming….

After sharing our feast with our Nico and Lindsay, we took a nap and awoke at 11pm to continue on to the Turks.  With the winds at 10-15 knots on a close haul, we were able to have a beautiful night sail with a sky full of stars and a trail of phosphorescence in our wake.  Getting through Sandbore Channel proved only mildly challenging as the 10 miles of the shallow "channel" was sprinkled with coral heads, so visual piloting was absolutely necessary.  We are now anchored in Sapodilla Bay on Providenciales in the Turks and Caicos.  We will spend the next couple of days here awaiting another weather window to open up so that we can take our next passage safely.  I'm not sure what we're going to do in terms of fun activities as spearfishing is highly forbidden here and lobster season is over.  I'm sure we will find something…

Passing Gas

With our return from NY, it was time to get down to some of the periodic maintenance we had let go during our extended stay on the hard.  Now that we are back in the water and the weather is starting to warm up, we thought it would be nice to have our dinghy at our disposal.  When we first moved down here, we had kept up with making sure to start our outboard engine at least once a month to be sure that the carburetor wouldn't get gummed up from stale gas. (Gasoline degrades to shellac when left unused.)  A carburetor is a device that blends air and fuel for an internal combustion engine and if its not working correctly you're dead in the water. When we got on the hard, that motivation faded fast, and the maintenance got put on the back burner.  Bad idea!  Frank has spent the past couple of days trying to get our outboard started and running correctly. Before this, he has had very limited  (i.e. zero) experience with small gas engines.  At this point, he has disassembled, cleaned, and re-assembled the carburetor and fuel lines at least 4 times, re-gapped the spark plugs, and checked the impeller nearly as many times as well.  It turned out that aside from the initial dirty carburetor, a simple 10-cent O-ring in the carb was causing the engine to run poorly.  

As far as we understand, carburetors tend to be the main culprit when an outboard either refuses to run or runs poorly. Frank was a bit apprehensive when he started taking apart the carburetor for the first time without any instructions, so he made it a point to chronicle his experience in case anyone else out there is in the same predicament.  Our outboard is a 4 stroke Nissan 9.8 and should be the same as the 8hp Nissan as well as the 8 and 9.8 Tohatsu, though I'm sure this is relevant to a lot of other small outboard carburetors as well.   

The first step is remove the carburetor from the engine.  To do that, first, you need to remove the throttle linkage from the carburetor body by loosening the set screw and sliding the connecting rod out.

Set screw for throttle connecting rod

Be careful not to lose the rod as there is nothing holding it in place on its other end.

Next, the choke connecting rod must be removed.  The small white plastic retaining clip rotates down freeing the rod.

Remove the hose connected to the top of the air box from the engine side.

The fuel line must also be removed from the back side of the engine.  Some gas will most likely spill out as the line is removed, so have some paper towels handy.

Fule line

Now that its all freed up, its time to remove the carburetor (as well as the air box as it comes off with the carb) from the engine.  Loosen the 2 10mm bolts and the whole shebang should easily pull off.

At this point it's time to take the carburetor to a CLEAN work surface to continue disassembling it.  On the bottom of the carb bowl there are 4 phillips screws that need to be removed.  Once off place the screws in a small dish so that they don't get lost, and separate the bowl from the carburetor body.  There  will most likely still be some gas left inside, so its best to do this over a disposable plate to avoid making a mess.

Screws attaching the bowl to the body

Inside the float is visible, and can be removed by loosing the phillips retaining screw.

Removing the retaining screw that holds the float in place

Once freed up gently lift the float body straight up; careful not to lose the needle in the process.  Remove the needle as well as the hinge pin form the float and place them in a small container of carb cleaner (a shot glass works well for this).

Floate with the needle and roller pin still attached

 Now with a flat head screwdriver remove the two brass screws that are visible.

Larger of the two brass screws

They are easily stripped so be careful.  Once removed, place the screws into your small container of carb cleaner along with the needle and pin.

Removing the smaller screw that hides the jet

Under the smaller of the two screws lies the jet.  You will need a small flathead to get down in there and unscrew it.

The jet is visible in the lower hole

The jet is one of the most prone places on the carburetor to become clogged by small debris because of the tiny passages it contains.  A specialty carburetor jet cleaning tool is available, however, a piece of mono-filament fishing line will work if your cheap like me.  The idea is to clear out any debris or gummed up gas from the tiny hole down the center of the jet.  A soak in the carburetor cleaner will help loosen all the nasty stuff up.

Next, flip the carburetor over and remove the SS plate from its top.  At this point the carb is as disassembled as it needs to be for the average cleaning.  Take the body outside along with the bowl that you removed earlier and blast it all with the carburetor cleaner.  Make sure to pay special attention to all of the small holes and passages through out the body, and use a liberal amount of cleaner (this is no place to skimp).

When your sure that the carb body, bowl, jet, needle, pin, and brass screws are absolutely positively squeaky clean, you can begin to re-assemble everything.  This is a good time to check the gaskets and o-rings that you removed and replace any damaged ones.  When you have everything back together and mounted back on the engine the last thing you have to pay attention to is the adjustment on the throttle linkage.  With the throttle set to full on the handle, the throttle on the carburetor should hit its stop.  If it doesn't just loosen up the set screw and re-adjust until you have it right.

And Bob's your uncle….(in Frank's case, that really is the name of his uncle and grandfather!)

Here are some random before and afters we have laying around.  Forgive me if some of these are repeats from past posts:

We lived like this for months
We found this in our old exhaust.  It was used to
make up the difference between 2 different sized
exhaust hoses.
This came off our old stove while I was cooking
Clustf*$k!  We couldn't figure out where half this
stuff went to, so Frank just redid it. 
Heap of crap in bilges before it was redone and organized
Fitting for one of the old fuel lines.  Almost
completely clogged :(
After!
New plumbing
None of these wires went to anything!
