40 Horse Johnson

6 posts in this topic

I just bought a new /used Lund with a 40 Johnson 1993. It has what appears to be an early oil injection system( no more pre-mixing) I asked the seller at the time about any low oil warning lamp or a auto shut off.There is none! Now we all can be a little forgetfull at times but this could be an expensive mistake! Are there any retro units that could be installed to prevent this from happening? T-290

I once owned an '88 Johnson 40hp and that was a pre-mix model. It turns out that I once had an incident where a buddy and I forgot to add oil to the gas on our spare tank and when we hooked up the spare tank and went full bore across the lake, the motor recognized the problem, and automatically shut off! They have sensors in the motor that detects oil and prevents a blow out. I never had any warning signals or anything...just a plain jane motor.
I am sure yours has these sensors.

Buddy of mine has a 40hp Johnson not for sure the year either a 90 or 93. It is oil injected, oil pump quit working motor didnt detect problem. Now he needs new head and pistons. I would be careful with the oil injected motor. Buddy was told if he fixes motor he should just mix oil in the gas. This way you know for sure its getting oil.
Just my two cents worth......

    • Three favorites at the moment.  By the time they upload, I may change my mind.
    • A few from Maplewood State Park on April 16th.  Non-professional, but they stood still long enough for me to get 'em.
    • You might be able to figure things out this week.  How big is your sump basket?  Is the  pump kicking in now?  Sit there for 15 minutes and count the number of times it cycles.  That should give you a decent idea on how much water is coming in.  Then figure out about how high the water has to go before it flows by gravity.  The spec for the pump will say something like that it can pump 2,000 gph at 10 feet of lift.  (the gph drops dramatically the higher it has to pump the water).  The answer to your specifics will give you an idea of how big of a pump you need.  If you match the size of the pump as close as possible to the amount of water your will face you can maximize the amount of time the battery backup will last.   Faced with this problem I took a standard boat sump pump and modified it so I could hook up a garden hose.  The I took an old shop extension cord and wired the pump so I could hook it up to a car in the garage.  So just prior to having Noah float by I could hook things up in the garage and be good to go for as long as I had gas in the car to pump up the battery.   Now that I am adult I bought a generator and wired the house to take care of things.
    • Inevitably at least twice each season I will leave the house, drive 45 minutes and walk some of my favorite grouse spots for hours and hours, seeing nothing.  Admitting defeat on that day, I will drive 45 minutes back home, only to find a covey of birds in the driveway...
    • Colonel E.H. Taylor Small Batch Maker's Maker's 46 Bulleit Glenmorangie Highland Single Malt   Copperwing Distillery in St. Louis Park has a nice smooth whiskey. Supposed to introduce a new bourbon in a couple weeks too.
