    Converting from a 1958 18 hp to a 1956 30hp Johnson

I see the 1956 just has a choke and start button configuration with only a wire going to the starter solenoid and the mercury safety switch. For the choke...

    1954 Johnson RD-15 Cooling system

    I just bought a 54 Johnson RD-15 25 Hp on eBay. I have seen some reference to the " water tubeless" design on the lower unit. I'm not clear on how that works compared to the water pump tube I see on my 58 FD-12. Any clues. Also, in general, I know the RD's changed style in 1955. Other than...
