Tell me more about your boat, engine, propeller shaft speed and the existing saildrive.
The boat is a custom built Lancer 36, originally
built as a race boat with minimal furniture.
The boat displaces 10,500 lbs on 29' LWL, so
it is very easily driven.
The engine is a Volvo MD 11C with a 110S Saildrive.
When I am able to get the machine started, which has always
been an issue, it will push the boat at 7.5 knots at 2500 rpm.
The shaft output is rated at 17 kW at that speed.
The ratio is 1.66:1.
The current prop is a 2 blade fixed , maybe a 16"x11", it seems
to be too much prop and the acceleration will throw off your
feet when you ease it in to gear. I will eventually go with a
folding prop of some sort.
I am guessing that I will not need a thrust bearing for the belt
drive, but I will build a composite structure to support the
Saildrive, since it was supported by the engine.
i do not know how yet to configure the ground loop
for the electrical system, that was connected to the
My expectation is to get into and out of the slip,
we are sailors and not motorsailors.
