I recently aquired an unknown outboard, it is a mixture of orange and white, The only markings on the cover is a number 4. I managed to find a half legible serial number on the side and a part number off the leg. Having researched it a little bit I have deduced that I have a Cresent Marin 4 or Monark 4.
Apparently this is the same engine as a volvo archimedes penta 4hp. It has good compression, nice clean gearing and have cleaned carb and fuel tank. Unfortunatly there is no spark.
I have removed wiring from cut off switch, also the wiring went to a panel at the front with 2 small holes in it side by side. I have removed all of this wiring and connected straight from primary coil (on stator) to points, This is what the wiring looked like it was doing in a round about way. Would like to get engine going, if need to stop can just cut off fuel, block air or worst case remove carb (easy to do).
I have checked primary coil for resistance (ok) secondary coil from spark plug lead to other output terminal reads 3.6kohm and I believe it is supposed to be 6ohm.
The secondary coil is encased in plastic and I have tried to remove this with no joy.
Where can I get parts from? (I'll post a picture tomorrow of stator and see if anyone recognises)
The secondary winding has a part number of Bosch 11Z 3, I was hoping to renew this but can't find anything similar
Which sparkplug do i need for this o/b?
