[AirForceF111D]

Hello, I am new to this forum. I am also am old man, so this is my first forum too. I have a 1978 Baja 18' open bow jet boat. It has a Hardin H300 motor, which is a Old's 403. I am desperately looking for a Hardin Marine Owner's Manual for the motor. It has all the specifications from the type of oil and plugs to the bore stroke. If anyone knows where I can find or purchase one, I would greatly appricate your help...

Thanks for your time!
