Hello everybody,
At first I like to introduce myself here and since two days I am a proud owner of two LISTER CS 6/1 baby's.
One is born in 1956 and the older one in 1938, lucky me :-)
One of this baby's, the younger one, is already rebuild from a real Lister master and in pristine condition, the other one will be my guinea pig to learn everything about this great engines.
At the moment I am stripping the older one apart and try to get her running again.
I will use the younger engine in my boat, which I am designing at the moment and will start building shortly.
Boat will be 33' long, 6' wide, draft 2'4", weights 3 tons and will be used for extended Pacific Cruising.
This was the whole idea to get involved with Lister's, in my mind the most reliable engines on the planet.
Power to the propeller will be transferred via a belt drive, which will drive a shaft to a gearbox, from the gear box will be a second shaft which will drive the propeller.
Should work out fine.
I have a problem with the right dimensions for the propeller, my software tells me that I should use a 18" x 16" propeller.
But the engine produces only 6 HP and I guess that this prop would be too BIG.
I know that the CS 6/1 has an enormous torque (comparable to a modern 30 HP YANMAR marine engine) and maybe this size would be OK, who knows
The second problem I cannot solve at the moment is a proper cooling system.
I guess that I have two options: Radiator or Keel Cooling
I like to keep everything as simple as possible and therefore like to avoid pumps or fans, they always give troubles sooner or later.
A cast iron radiator (from central heating system) would be a simple solution, can anybody give me an idea of how big this radiator should be to be used in tropical climates ?
Have seen a few pictures in this forum and they where very different, one very small one and one quite big, so what would be right?
Maybe a big tractor radiator would do a good job too, how big this one has to be to cool my baby without a fan ?
Keel Cooling would be an option too, but no one can tell me the right size.
If anyone has experiences with a CS 6/1 in a boat, suggestions about propeller size and cooling system would be really appreciated :-)
Will put some pictures from my rebuilding story on my web site shortly.
Thanks for every comment in advance and it is a pleasure to be a member of this great forum.
Everybody has a good day
