Re: 1950's Johnson OB
Hi Dennis,<br /> The 1956 30hp is not quite 36 cubic inches, while the 1957 35hp is a little over 40 cubes - same stroke. Many parts are interchangeable, other than the cylinder head, block, & pistons. From the belly-pan on down are pretty much identical. Magneto parts, carb parts, lower unit seals, impellers, hoses, tank rebuild kits, some gaskets are all still readily available. Other parts might require a bit more hunting around. <br /> One word of advice - I see similar motors go as swap meets all the time for $50-$200 depending on condition. Beware of some motors on eBay, as they tend to be overpriced. There are deals to be had there, but there are also some motors with reserves that are outrageous. Those motors are fairly common - don't be fooled by "rare" and "unique" descriptions...<br />- Scott
