And Bob's Your Uncle

We have been waiting for the past 2 weeks to finally splash the boat.  It's looking like we have another week to go before a slip is going to open up.  Hurry up and wait!  We have decided to stay at the docks at this marina for a little while longer once we get back in simply because of the price for living aboard here.  We still have a list of projects to do once we are in, but it's looking like we are finished with our "on-the-hard projects".  Hallelujah!   Here's a quick run down of things that have kept us busy for the past few years.  I think I may have missed some, but you get the point:

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!

Mad Props


Because we re-powered, we needed to find a new propeller that would better match the performance curve of our new Yanmar 4JH4-TE.  After hearing good things about Campbell Sailer props, and how they reduce drag when under sail, as well as prop-walk when under power, we decided to give them a try.  One of our friends at the marina has touted them to have reduced drag on his boat so much that he gets an extra half of a knot to a knot more under sail than when he had a traditional fixed prop.  The price for the Campbell Sailor is comparable to a normal Michigan propeller which made the decision all that much easier. We've heard from a lot of people that when they first get them they always wonder whether or not there was a mistake made and they were sent too small of a prop by accident, and funnily enough, we thought the same.  The difference is humorous, and with it installed, Moitessier looks like a fat man wearing a tiny hat.  Hehehe.  

My pretty Proppy garden

Before we installed it, Frank had to lap it to the shaft.  This process is better explained here. Basically, lapping fine tunes the fit between the shaft taper and the propeller, making a tighter tolerance fit.  After it was lapped, Frank sandblasted it with a sandblaster borrowed from a neighbor on a steel boat (God, I do NOT miss owning a steel boat!) then applied Interlux 2000 primer followed by 3 coats of Pettit Trinidad Hard Bottom Paint on both the prop as well as the shaft.  The thinking behind this is that hard paint holds up a lot better to the wear incurred on the prop.  We had inquired with the yard about their experiences with various methods of reducing prop fouling, and this is what they had suggested.  They say that they get 2-3 years on the large sport fishers doing a lot more motoring than we will.  Again, we'll see how it all works out.  

The fit before lapping.  The light areas are the only
 places of contact between the shaft and prop.

Strut Your Stuff

In the process of cleaning off the strut to be bottom painted during our bottom job, Frank noticed several cracks that ran horizontally across it.  This is the aperture that holds our second cutlass bearing that in turn holds our propeller shaft in place.  As we all know with metal, a noticeable crack usually means severe corrosion, and we didn't want to risk having this fail on us.  After freaking out and thinking about what the heck to do with this, we started to do some research on how to get this piece re-made.  We had considered both braising and TIG welding as a way to repair it, but quickly ruled that out after talking to a few local welders.  This left us with having to get a new piece cast, as the old one was not an off-the-shelf part.  Most of the foundries we looked into had a lead time of 12-14 weeks.  We were a little disgruntled to think that this final and unexpected piece of the puzzle would keep us on the hard for an extra 3 to 4 months.  After calling every place we thought would be an option, we found one over in Washington that promised to custom cast it with a 2 week lead time. The price for this including the tooling and new cutlass bearing, surprisingly, was comparable to getting a new off-the-shelf prop (maybe they didn't realize that it was going on a boat and forgot about the 200% marine grade upcharge).  

Original strut
Cracks :(

Frank wanted to remove the strut without having to pull the shaft.  We were told by people at the yard that this was not possible, and since Frank is super stubborn he wanted to prove that, indeed, it could be done.  After rigging up ratchet straps to pull it off, as well as heat guns to heat up the caulking, he was finally able to get it off with the help of a paint scraper and a hammer.  After removing it from the boat, it was a matter of shipping it over to Morel Industries in Seattle, WA.  The strut weighed a hefty 50 lbs.  We chose Morel Industries not just for its quick turnaround times, but also because of their reputation as a competent foundry (they are responsible for casting the pieces required to make the tight rope that Nik Wallenda recently used to cross the Grand Canyon.)  The foundry used sand casting to replicate the old part we had sent to them.  It took 4 weeks to get the new part (one week each way to ship) complete with a new cutlass bearing pre-installed.  Even though the new part was as close to an exact replica as could be made, subtle differences still occur due to shrinkage during the cooling process.

Finally off

The new piece needed to be properly aligned before it could be bolted back on the boat.  This is the fifth job we've hired out as the precision needed to align the piece was not something Frank was comfortable tackling on his own.  John, at the yard, was responsible for doing this work.  He first had to get the shaft to sit straight where it wants to sit without the droop caused by its own weight.  To accomplish this, he took the length protruding from the boat multiplied by the known weight per inch for a 1 1/2" shaft.  He then took this number and divided it in half.  With that, he knew how much force had to be applied to the aft end of the shaft to get it to sit dead straight.  Once that was accomplished, he then had to align the strut to the shaft and the boat.  He first buttered up the strut and the boat with thickened epoxy.  While it was still wet, he screwed 4 screws (one on each corner of the strut) through the strut and up into the hull.  He was able to use these screws, by tightening and loosening them, to align the strut to the shaft, the way you would align an engine.  When it was properly aligned, he let it sit until the epoxy had fully cured.  Once it was all dry, the adjustment screws were removed and the 6 bolt holes were cleared of the excess epoxy.  We used silicone bronze bolts to firmly secure the strut into place for good, as the old bolts were stainless, and stainless steel and bronze do not play well together underwater.

Installed
Now that this is finally installed, it is just a matter of sandblasting it along with the shaft and propeller before applying 4 coats of Interlux 2000, followed by 3 coats of a hard (non-abletive) bottom paint to keep it all from fouling.
