Re: 10hp seahorse 1956---worthy project???
Ibe--I'm'presuming your motor is a QD-17. I have had mixed luck with starter springs because most of the time when I disassemble the starter pulley assembly the springs flies out onto the floor with great energy. I have two manuals: a Clymer manual for the 1956-1972 Johnson/Evinrude models, which is fairly good, and I ordered a Johnson Service Manual from Ken Cook. Do a Google search and you will find the site. I also got an original 1956 owners manual from them. These manuals have good pictures to go along with the explanation. Back to the spring: It will seem obvious when the starter housing head is removed. Once the center bolt is removed, be careful, because the next step is to lift the pulley from the housing, which will cause the remaining spring to fly clear if not careful. The new spring needs to be greased, the lack of which probably caused the old one to break, or just old age, then coiled into the starter housing counterclockwise (looking down at the assembly). Look to see where your existing spring is attached before removing it completely; this shows you how to re-attach it. Allow yourself some time to do this, unless you are familiar with this type of operation. The manual gives you a good guide.--Back to one of your earlier questions about fuel consumption. These motors are gas eaters, with much of the 24:1 gas-oil mixture going to lubrication and not power. They burn dirty, and are smoky, but better too much than too little. I have a four gallon tank which my motors make short work of, but the joy of having one of these solid old workhorses is worth it. Best of luck on the spring.
