Verify that the stainless steel tang that holds the plastic choke lever in place is doing its job, after a while they need to be re-bent back in place to apply enough tension on that choke rod notch to hold the choke in position. Evinrude in those years used a different 5 digit model code, as 10424 S. It had wishbone shaped wedges near the plugs in the combustion chambers. Many boaters are not interested in these motors, preferring the electronic ignition, and I have to say if I had a choice I would also, but the older point system has performed quite well until modern technology came along. Twist grip to start position.
Also the shift handle is black plastic. Manuals available for most year models: 1965 1967 1966 1969 1968 1971 1970 1972 1971 1973 1975 1974 1977 1976 1997 2000 1999 1985 1987 1986 1989 1988 1991 1990 1993 1992 1994 1993 1996 1995 1998 2002 2001 2004 2003 2006 2005 2006 2007 2008 2009 2010 2011 1979 1978 1981 1980 1983 1982 1984 1983 1986. It makes sense when shutting down these motors using a single carburetor for what may well be a extended period of time, to disconnect the fuel line and run the motor unit it dies, using up all the fuel in the carburetor. And the upper latch cowling lever is located at the rear and under the edge of the cowling, rotating it down allows you to remove the upper cowling to access the engine compartment. If you need to rewind the old spring, or replace the large wound coil.
Depending on the year there will be 4 or 5 pins. Which brings us to replacing the spring, take the old one out, but be careful in that if it uncoils from the housing it can be dangerous, like a snake whipping around. When re-installing the thermostat on these, it might be wise to add some anti-seize to the cover threads. Instant download of the factory repair manual for 2007 Johnson two-stroke, two-cylinder 9. If you make the conversion to the newer head, the coils may be slightly different configuration, but they can be made to function as the mounting bolts are all the same locations. Now you can wind the rope back onto the spool then locate the spool's inner peg into the eye of the spring. It is not unheard of to have a bad new spark plug, but rare.
If you need to check on parts and do not have a actual parts list booklet, one of your best sources is They have a complete listing of about all of the Johnson and Evinrude motors showing exploded parts views with part numbers where you may be able order parts online from them. If you hook up the wires to the battery backwards, you will more than likely ruin the rectifier. These buttons for both type 3 and 4 also incorporated a man overboard kill switch. My articles are probably the most complete information you will find for the 9. However there are a few things to keep in mind.
One thing that I have found is that the pre 1977 motors which have the points and condensers seem to be a little cold blooded, in that they have to warm up before they will stay idling as for trolling. A machinist is naturally going to be more experienced with the procedures. These factory gaskets have a self sealant on them. Rather bad it you are running in salt water. Another problem could be leaky reed valves at the reed valve base. The other larger hole washer needs to be installed under the anchor bolt's head, otherwise the starter gear will not stop on it's upward motion and bind in the flywheel gear teeth.
Neutral Safety Position : The electric start versions also have an electronic neutral safety switch, which is an inline switch between the actual starter button and the starter itself. A problem in buying a used carburetor is that the part number may be hard to read as it is only stenciled on. To kill it by either the clip missing or by you pushing the button, you connect the wires, grounding out the wiring, killing the motor. This point setting is usually stamped on the armature plate under the flywheel, and on the inside of the flywheel, so if you remove the flywheel you can see this setting. With the motor assembled in a running situation this Ell is about impossible to get at.
All 15 hp motors for both Johnson and Evinrude were called 15hp. The idle jet venturi system is also slightly different between the two. And a dose of compressed air and flushing did not solve this one that was stuck open. And this engineer had never worked on one of these motors. The only thing I could come up with was that maybe it was on the verge of failing when he took the motor out of service, just setting in a heated room allowed the internal components to break down and short out. It is suspected that possibly they want the design to run for long enough to really perfect a better part? It also needs to burn the oil that may accumulate in the piston ring grooves so they do not become seized in the grooves which create more problems. He was from the old school and thought that at that time the electronic ignitions were far less reliable than points equipped version 1974-76.
If a problem occurs, check the 2 hold down machine screws and the neoprene gasket under the fuel pump. No powerpack was needed nor used on these early magneto ignition motors. As shown, the 1 red wire comes from the starter switch and attached to the terminal block. For an explanation of possible water tube grommets deteriorating where they attach to these exhaust tubes, possibly causing water blockage for a link to my water circulation problems article. When I asked today for help with the ignition on the 9. The same applies for the thermostat cover. If you turn it on full blast, you may blow out a internal motor water tube grommet, or at least force water past it and very likely will see water coming out of the juncture of lower motor mounts and the lower where there is a gap near the shifting rods.
I suspect that could be from 2 situations. I have seen it on 2 1974 9. The word is that the newer thermostats are constructed of a stainless steel, a better material if exposed to salt water and operate better than many of the older ones. Hard Starting When Cold : The one most common problem with hard cold starting, if the motor is in reasonably good running condition, can probably be contributed to someone who uses the motor strictly for lake trolling and is prone to adjust the idle jet lower than it is actually designed for. These holes are there so that when the motor is being run in the water without being in gear, the backpressure is vented out thru these holes. Now it will fall on top of the block, so you can retrieve it with a small magnet.
This, in addition to extensive research, is how Clymer repair manuals achieve an unmatched level of detail. For safety, disconnect the spark plug lead, then ground it to the cylinder head. There is also a small spring and plunger inside all this, making it slightly hard to keep everything in the proper locations while making the final assembly. This one was so bad that after I installed a new thermostat, I dissected the old one, it had the small internal shaft seized so tight inside the outer tube that no way could it operate. It does make sense that bad fuel could have been one component of the problem. Even after the new overboard water indicator tell tale was implemented, the old vent mist holes were left in the upper housing.
