I have a 65-68 OS S30 r/c marine engine I purchased quite awhile back & it seems to have never been run .
It has no starter belt marks on the flywheel & it has very nice compression.

Now to the point ...

Does anyone have a manual They can copy & send out to me on this engine ?
It has two barbed connectors on the back of the crank case & the pressure port for the fuel is on the muffler ,so I am not sure what the connectors are for unless they are connected to a cooling coil to keep the bottom end cool.
I don't want to take it apart to find out since gaskets are more than likely not available.

Thanks

Ok . I figured out the barbs on the back of crank case are for cooling . I took the cover off to find out .


I still would like a copy of the manual for it if anyone has one . Thanks

Post #5 has a pdf of the manual for the OS S30 R/C, it is the airplane version of your engine:
