I have spent some years "cruising" through forums
, hardly posting
. But in my research
for this project
there was no discussion about this type of conversion. So, I decided to register and give back to the collective...
is a Falkon with 12VDC 1.5kW motor
. I just added a belt driven VTM clutch pump
to the main, primarily for this windlass
and a pot hauler. There is plenty of aversion to using hydraulics from what I read of other's opinions. Here is how I arrived at removing the electric motor
After a sleepless night on the hook, blowing 25-30kts with caps, swinging around between three other boats, two of them dragging, I hauled the anchor
. The batteries
must have been strained. I knew the short run to another bight would add some capacity, but I did not expect the resulting failure of ample capacity to restart the main a day later. No problem, start the aux, and charge away for a while...then realize the alternator
is not putting out and replace it with a spare. After some more aux run time, I had enough juice to coax the cummins back to life. This was almost a three day event, and really messed up some good fishing
I have since completely rebuilt the battery
system on board, but I have never been excited about having to re-set an anchor
, and have limited my ops to only one down/up of ground tackle per day.
Existing electric motor
works out to about 2hp at 2400 rpm
on a 4:75 worm consuming around 80-150A. This is about 65 lb-in of torque at the motor
Using Parker hydraulic motor MGG2-16, I expect to be able to idle the main and have similar output torque from the hydraulic motor. Also, I have additional flow and pressure capacity to provide 3750 rpm
, 75 lb-in torque, around 4 hp.
The one issue I am down to now, is the custom mounting plate to go from metric electric
motor mount to SAE 4-bolt, and a short jack shaft to adapt the motor to the worm gear
. There seems to be plenty of room.
I chose to install a spool valve, mounted so handle goes up/down, that is spring return to center after up, but friction detent down. This way I can clutch
out the wildcats, and use the gypsy
without hand on valve. Hauling in would always require hand on valve.
is a heavy steel
Roberts, with all chain rode
, so it's getting up there in weight. Just thought I would offer up my thoughts, in case anyone else was considering this type of conversion.
