Nissan NS3.5B Kill Switch

[jauguston]

I see my newly aquired engine has a kill switch that is spring loaded "OFF" with a orange plastic clip holding it in the "ON" position. For my use that seems like it would be a PITA. Do they have a conventional "ON-OFF" switch I could put in instead?

Do all three bolts under the cavation plate hold the gear case on or is the one that looks like it holds the zinc only for the zinc. Wondering how many of them I am going to have to break (-:

The zinc bolt is only for the zinc. The kill switch with lanyard has been required, by federal law, for quite some time now.

Thanks Elvin.

I have not run the engine yet due to the busted head so the question is, how is the engine normally stopped. Will it stop with the throttle lever all the way down?

Just for my education what is the lanyard supposed to be used for or is it one of those "The government says it must be there just because" (-:

The kill switch also acts as a stop button. With the lanyard in place you can still press on the button and stop the engine....You have to keep the button depressed until the engine completely stops. Sometime back in the late 80's/early 90's the Feds decided that people were being thrown out of boats in record numbers(?). The idea was that people would attach the other end of the lanyard to their person and when they were thrown out of the boat the engine would stop...Instead of circling back for the kill. I think it was a good idea that 99% of people ignore because "It's not going to happen to me"

A few years ago I was boating in the cheasapeake bay and a guy had been thrown out of his boat. His boat was circling him like a shark. The coast guard was there matching the boat speed/circling and throwing a rope& bouy trying to hit the throttle to stop the engine. They eventually did but not before they broke out the guys windshield and a couple of gauges. The guy was lucky though that the boat didn't circle back and hit him. All of this would have been avoided if he would have just used the safety laynard.

And Elvin is right, to stop the motor, simply press in on the button instead of pulling the cord. Both methods work.

And more importantly, attached the cord to yourself. People get thrown overboard more than you realize.

Re: Nissan NS3.5B Kill Switch

Got the gear case off and stripped .The stuck bolt by the zinc luckily broke right under the head so I had something to get ahold of after a lot of heat and dead blow hammer blows to get the gear case off. The four bolts on the water pump were tight but came out. The upper bearing plate below the water pump was a bi**h to get out. The vent hole was plugged and the top bearing was shot so I had to get it all apart.

I have the utmost respect for you guys that deal with salted up engines for a living. What a mess.

This afternoons project is putting it back together.
