    Prop Slipping? Cavitation?

    We went camping this weekend at the lake and thus were able to get our pontoon out and really run it around. We have a 24' pontoon with a 1995 Johnson 28HP motor. I realize that we are underpowered, but that's what came with the boat. My question is this, when I got several people on the boat...

    Seafoam - How Much?

    I was wondering how much Seafoam you are using per gallon for maintenance/fuel stabilization? The can says 16oz treats 6-12g of fuel/oil mix, avg 2oz/g. Do you mix it at 2oz/g?

    White Smoke - 28HP Johnson

    I put 10oz of Seafoam into 6 gallons of fuel when I refueled the boat today. After running around the lake for a bit I noticed some white smoke as I was idling into the dock. Would the 10oz of Seafoam in the 6g of fuel be enough to make it blow white smoke?

    Decarboning - Which Method?

    Reading through the boards here I have come across three different methods for decarbing a motor. I have listed them below; is one method any better than the others? Method 1: Take a can of seafoam put 3/4 of it in the gas tank, with only 1 gallon of premixed gas. put the rest in a spray...

    Tilt Control

    I have a 95 Johnson 28HP motor. It does not have power tilt/trim on it. Is there anyway to "lock" it in the down position? If I reverse it quickly it has a tendency to kick up out of the water. I can pull it out of the water and it locks up. To lower it I pull back slightly and move a small bar...

    What is this buzzer for?

    I have a boat with a 95 Johnson 28HP motor on it. I was under the helm and saw a buzzer hooked into the wiring cable from the motor. Is this an engine overheat alarm? Is there any way to test the buzzer/sending unit if it is an overheat alarm? Would it be possible to install a light, ie an LED...

    Carb Rebuild Observations/Questions

    I just finished rebuilding/cleaning the carb off my 95 Johnson 28HP and I have a couple of questions: 1) There is an orifice in the plastic carb cover called the intermediate orifice, part #9 in the diagram below. This orifice is open to the outside air. If you spray into it the spray comes out...

    Carb Cleaning - What to soak in?

    I got my carb rebuild kit today and I'm ready to tackle this adventure!! I have a can of Gumout carb cleaner and a can of compressed air. What should I use to soak the parts in, or is spraying with the Gumout sufficient?

    Carb Rebuild & Fuel Filter

    I am getting ready to rebuild the carb on my 95 Johnson 28HP. Somewhere online I had found step by step photos on rebuilding a carb. Does anyone happen to know that link? I was thinking I found it on here. I have seen tashasdaddy's thread, but this was a different one. Also, I want to add an...

    Replaced Plugs....Are These Normal?

    I replaced the plugs on my 95 28HP Johnson today. I have attached pics of the plugs I removed. Do they look normal? I was thinking they looked fouled. I was also able to get rid of the "lean sneeze" at idle by adjusting the low speed screw out, although when I came back later it started...

    Which Spark Plug for 1995 28HP

    I want to pick up a couple new plugs for my 95 Johnson 28HP outboard. I looked on the Evinrude/Johnson website but I could not find what plug I need. My engine is a J28ESLEOC. Can these be picked up at most auto part stores? What gap should I use? Gary

    Anchor Recommendations

    I just purchased a 24ft pontoon and it does not have an anchor. The only anchor my local Wal Mart has is a 10lb mushroom. That just doesnt seem like it would hold my boat. I am looking for suggestions as to what type/size of anchor I should get. Thanks, Gary

    Electric Choke

    I just purchased a pontoon with a 95 Johnson 28HP motor. It has an electric choke. The previous owner told me to just hold the switch until it clicks a couple times and then start. He told me not to hold the switch. Is this correct? How do these work? Does it stay on for so long and then turn off?

    '95 Johnson 28HP

    I just purchased a pontoon boat that has a 1995 28HP Johnson outboard on it. The seller told me that it had not been run since late March and it started up quickly and seemed to run fairly well, however it seemed to be loading up a little bit. I was thinking maybe it's gummed up from sitting...

    1979 Mercruiser Impeller

    I have a couple of questions. 1) I have found a 1979 19ft Kona boat with a 260hp V8 Mercruiser in it (thats what the owner says). Any idea which engine this might be? 2) The owner says that the lower unit impeller needs replaced. How hard of a job is this? I have replaced water pumps...
