Here’s the owners/operators manual. Not sure if I have the parts breakdown.

Glancing thru it I see 16:1 is the recommended fuel mix and not 24:1.

One Canadian quart 40 0z into 5 canadian gallons (160 oz) = 40/800 oz 20/1

one US quart 32 oz into 5 US gal (128 oz) = 32/640 oz 20/1

easier is 1 L of oil in 20 liters of gas = 20/1 🙂

Just re-tapping into this topic as it has been a couple of years, but does anyone have a pdf copy of the parts manual for the Johnson RD-13 1952 25hp?

I see the owner’s manual above for the 1952-54. Is there a unique owner’s manual for the 1954 25hp RD-16? Does anyone have one? I have the parts catalog for the RD 12, 13, 16, 17C, and 18.

While the part # for the manual remains the same there were later printings which are different. In the lower left corner you see the part # 302765 2-54 which I think means a printing from Feb. ’54
Mine shows “Remote-Steering, Speed & Shift control” on the last page. I did not look for other differences. Sorry not for sale.
If you want other parts catalogs I have the following for sale RD-14, RDE-16, RD-17, RD-17S, RDE-17, RDE-17C, RDE-18, RDE-19M and RD-21
