Johnson outboards, model RDS-24L, would be a 1962 year model, 40 hp. the boat motor is a 50 hp.
More than likely 10W30. Your owner's manual will list the exact weight required. * I drive a 2000 Plymouth Breeze with a 2.4L engine. The owners manual recommends 5W30 weigt oil.
You didn't say which engine, but, The 24L DOHC engine is located in the top coil pack cover It is a rectangle shape plugin next to the fuel lines. On an 2.2L OHV engine follow the plug wires. It will be underneeth the coil pack. Either way the coil packs are sitting on top of the ICM....

For all the 2.3, 2.4L QUAD 4 engines, the head bolts are Torque to Yield. The porper torque value is 30ftlbs PLUS a 90 degree turn of the wrench. The bolts must be new every time ( NEVER REUSE OLD BOLTS). The torque values and proper sequence are including in the box the new bolts come with. BUT honestly, the torque value is 65ft lbs like all GM Chevy motors have been for eons.
