Nissan 9.8 Outboard Two Stroke Problem

They say confession is good for the soul. This weekend my brother and I took the "new" 1965 Cal 28 for a spin in San Diego Bay. After driving all night from Phoenix, we elected to motor across with a Nissan 9.8 outboard in the rain to Coronado to the Burger King. Thereafter, we planned to motor over to the fuel dock near Tom Ham's Lighthouse to fill the tanks. We never untied a sheet, nor hoisted a sail. The Genoa remained bagged below. The two anchors were stored away, too. Big mistake. We pulled the kill switch on the Nissan at the public dock in Coronado and it just kept on firing. It would not shut off. We pushed and pulled on the kill switch, but nothing happened. We decided to unplug the fuel line. We returned from our Burger King breakfast and hooked the line back up. I pumped the primer a few times and noticed a vaccum in the line. I thought it would slowly resolve itself and thought about it no more. I started the engine, and it ran smoothly. We decided to wait and let it run a while, just in case. We finally headed out, convinced the Nissan was running smoothly. About 40 yards from the dock, the engine died. We quickly tried to restart it, but to no avail. My brother kept working on the motor, while I looked to hoist the sails. The wind pushing on the hull quickly pushed us across the bay towards the rocks on the other side. Hurried attempts to hoist the sails (all sails either remained covered, tied down, or down below) proved fruitless. The shore line rapidly approached. With about 20 feet to go I prepared to fend off at the Embarcadero Pier, where several fishermen and gang members watched our approach with interest. My brother some how managed to keep the boat from striking or going under the peer for about 20 minutes. While fending off and battling large wakes, wind, etc., the gang members shouted to the approaching police boat, "they just dumped three plastic bags of cocaine in the water when they saw you coming!" They also commented, "Looks like Broke Back Water." Wewere able to laugh about what almost proved to be a total disaster. We convinced the cops to give us some time before they called Boater Assist. We discovered the vacuum problem and were finally able to pull away unscathed, our egos totally deflated. Here is the question. What's going on with the kill switch? Is this an easy fix? If not, is there some mechanic nearby who could remedy this problem without charging me an arm and a leg? Sorry so long a message.

My only suggestion would be to check the plug and see if it is fouled. Maybe it was "dieseling", that is hot debris around the element that ignites the gas mixture and keeps the engine firing even with the ignition off. You didn't say how many cylinders but I'd change the plugs and see what happens. There must be better mechanics around here than I but that's my $0.02. Mike Kennedy Conquest cal 40 # 96 >

If the outboard has been unused for a while, there's likely some gummed up gas residue in there, or something else chunky that migrated into a small place and stopped it up. You can clean it out using various solvents, or go to an auto parts place and buy a gallon can of carb dip that you can use on various other gas-powered devices. Just be careful of plastic parts. I also use a little rubber squeeze syringe for "compressed air" to blow things out. It's like a rubber turkey baster--a squeeze bulb with a pointed tip. Go to the drug store. Most carburetors can be disassembled carefully with out damaging the gaskets, if you are careful. I have a 1938 Johnson with original gaskets, although I finally broke down and bought new ones for the 1965 Sea King. And that little pump bulb on the fuel line is a gas pump, not a vacuum pump. It squishes gas up from the tank to fuel pump and then to the carburetor. Most of the fuel pumps are activated by engine vacuum, acting on a diaphragm, but that's not related to the fuel line bulb. By the way, I've had balky outboards that required me to keep squeezing that bulb if I wanted to get home. It's a sure sign of blockage in the fuel system. I had an experience like your many years ago. The engine died at an inconvenient moment. Couldn't get sails hoisted in time. Anchor rode wasn't secured to anchor. Big mess. My anchor is always secured the rode and ready to deploy now!!! Chris Campbell

Most outboards use a magneto to make the spark. A magneto makes the high voltage by the magnet spinning by a coil, no battery needed like for an ignition coil. You kill the spark by shorting the coil by pushing the switch. If the switch doesn't close, you don't kill the spark. Disconnect the switch and measure the resistance when you push the button, it should be less than a few ohms, or try shorting the wires, bypassing the switch, if it doesn't start, replace the switch.

I accidentally fixed my kill switch last week. After trying to start the outboard with no luck many times, I pulled the cover off and started poking around. I was getting a bit of a shock from somewhere down low when I tried to start the motor. I traced the wires and found a corroded and broken brown wire coming from a splice in the line. Notwithstanding the break in the line, the starter motor still functioned. I was somewhat confused by this. I carefully disassembled the motor and was a bit dismayed as a large part of the assembly went into the water at the dock. Undeterred, I forged ahead. I carefully snipped and stripped the visible black and brown wires protuding from the wrapped tape. I bought some tape and another two foot piece of similar gauge wire and returned to the boat. I untaped the rest of the line to find I had four different colored wires, and I failed to notice which colors were connected to each other before I snipped. I had a black and brown coming from the Nissan, and a yellow and red coming from the hull. I traced the lines back to the battery and sorted them out. I taped it all up thinking my starting problems were history. Not so. I pulled the two plugs and noticed they were very wet. Ever since the death of my kill switch, I used the choke to kill the engine. Turns out, my method finally caught up with me. I'd been flooding the engine and she refused to start. In the fixing process, I cut the rope starter and had a real mess on my hands. The rope recoiled into the housing. That was another challenge. I put the kill switch back on the throttle control, and voila! All worked wonderfully. I believed I was working on the starting problem. I was very happy to learn I fixed the kill switch. I fixed the rope pull, too. I then "dove the boat" in an effort to find my missing Nissan part. Success was realized on the third dive. I felt pretty good when it was all over.
