Ok you guy's are not going to belive this but I traded a 60's model 9.5 for this motor tonight! A few days ago I answered an add looking to trade for a 9.9 to 20 Hp for this simi-running 93 -15hp Evinrude with broken pull start. After a few emails I call the guy and he tells me that when he got it it ran good but all of a sudden it quit he put a new coil on and that is when the pull start broke he thinks the float is sticking also. So I tell him I might be willing to trade a 1975 9.9 thinking he would laugh at me but he says sure if its running. So yesterday evening we get to meet and I decided to through the 9.5 in the truck also. Well the 15 looks descent so I pull the pull start off and check compression which was not easy as there is no pull rope groove on this motor but with three pulls I was looking at about 112-115 on each cylinder. So next is spark........no spark! I start looking an there are what looks like mouse chewed on wires coming out of the power pack and several spors with fresh looking electrical tape. At this point I am ready to walk away and tell the guy so. He then tells me he is willing to add cash to the deal and he hasn't even looked at my motors yet. So I tell him I am not willing to let go of the 9.9 but may on the 9.5 he then asked how much extra cash I wanted. I was really floored and wondering what is really wrong with this motor but figure what the heck and tell him, no cash even swap. Done deal.
Make it home and tear into it! The pull cord was an easy fix, just set and rewind the coil spring. Then I start pulling all the electrical tape. Three if the wires coming out from under the fly wheel where slightly melted in one small spot but all were tapped to gather so able to short each other out. Fixed this and all bare spots then tried....dang still no fire!!!! That is when I look down at the tiller handle and notice a red button! Holly Cow! This thing has an emergency kill with no clip installed. Head out to the boat where I keep my extra clip and pop it on. Pull the cord one time and not only is there spark but she fires through the spark tester and runs for a second. So at this point I am stoked! I swap to the bottom cylinder to test for fire and.........none back to the top and none! So now I am scratching my head. About this time the wife makes it home and I am showing her what I feel is a diamond in the rough explaining what I have done so far and what is happening showing her the wires that I fixed and that is when I find the ground to the emergency kill laying in the bottom around the motor. When the PO changed the coil he didn't put it back. So I fix that real quick and just want to try it. She fired right up and ran great at anything above half throttle and like I have said before these little motors run great on one cylinder. After about another hour of checking testing and fiddling I have determined that the power pack is bad or half bad and only sending fire to the top cylinder.
