Another step forward in the outboard repair project

Sunday, December 30th, 2007

  I finished working on the lower unit of my outboard Merc 3.3 hp engine. As stated in previous blogs, the engine was lost at sea and then recovered. Though, filled with sand.

  The picture above shows the lower unit clamped next to the engine on my home made stand. If you look closely you’ll see all the sand still inside the unit. (more…)

wharves

  This chilly winter day is a good chance to write a little about Mattapoisett, why we spend our summers there, and why it’s the home port for Galatea. The picture above was taken of Shipyard Park and the Wharves on a calm early morning last summer while motoring the Jenhiu about the harbor. (more…)

Forget about making Biodiesel

OK, I was all gung ho about making my own Biodiesel fuel at home. How hard could it be I figured. You add some methanol and some lye to vegetable oil and bingo.

NOT!!!!

Bio-Diesel Conversion

Saturday, December 1st, 2007

   I’m excited by my upgrade plans this winter to convert Galatea into a nearly 100% “green” vessel for the 2008 season. She’ll be propelled by the wind or bio-diesel fuel.

  Bio-diesel is mostly vegtable oil. In fact, the Yanmar diesel engine in Galatea could run on pure vegtable oil. But that could pose potential problems in it’s actual use. That problem being pure vegtable oil is a highly viscous liquid. In order for vegtable oil to be used in a diesel engine it needs to be pre-heated to decrease it’s viscosity. Which is exactly what automobiles do for straight vegtable oil engine conversions.

  For sailboats, a pre-heater isn’t practical. The solution is using a blend of vegtable oil, methanol, and lye to create bio-diesel. These additives change the chemical composition of the vegtable oil to produce a fuel that has a low enough viscosity for use in a diesel engine. And the beauty of bio-diesel is that it can be mixed with petrol-diesel in pretty much any ratio. So, sailing up the coast of New England for a long trip wouldn’t be a problem with having to find bio-diesel. (more…)
