    I want to add a third toon of smaller diameter

    I have a 24ft pontoon boat that has 23" diameter pontoons. It has a factory aluminum deck and I built an enclosure on it to make it a weekend houseboat. The interior is minimum and I plan on keeping it that way. It currently has a Mercury Classic 50 for a motor. I had it on the Mississippi...

    How to test VRO system

    Just picked up a 1985, 70hp Johnson with the VRO. It hasn't been running in at least 5 years. Is there a way to test the VRO before I attempt to start it? I don't want to learn too late that the VRO wasn't working and ruin the motor. I've deleted the VRO on another engine in the past but...

    Troublesome motor??

    Sorry, thought I listed that it's a 70hp. Don't have the model or serial number. I've just been in messaging communication with the seller. I'll see if he can provide the serial and model #. Below is a photo.

    Troublesome motor??

    I am thinking of buying a 1997 Johnson 4 stroke outboard with fuel injection. I didn't realize they had fuel injection in those years. Is it true fuel injection and does anyone have any thoughts on this motor? Thanks for any input.

    yamaha 4 stroke cold start problem

    Above is the video on cold start issues with Yamaha's. My apologies on calling them solenoids. I believe the term is cold start valves. I have removed both and tested them and the needle moves slowly as it should when warming up. According to the video, that closes off the additional fuel...

    yamaha 4 stroke cold start problem

    The needle moves slowly when energized. Good to know that it only gets power when running. I checked with the key in the on position and it did not get power. First chance I get, I will start it up and ensure power is to the solenoid. I have tried several starting methods, including just...

    yamaha 4 stroke cold start problem

    I have a 2001, 80hp, Yamaha carbureted 4 stroke that will not start when the engine is cold. I have to give it a shot of starting fluid at the beginning of the day to get it running. It will start fine the rest of the day. I had the carbs cleaned last year by a mechanic. The motor has 2 cold...

    110 Johnson, sputtering and coughing

    Low 80's, 110hp Johnson that I can't get to run smoothly. VRO has been deleted. Plugs and coils are good. Fuel filter replaced. Had the carbs cleaned but not much faith in the mechanic. When I got it back it was leaking gas from the small fuel lines. He didn't replace them and I had to bring it...

    Recently picked up a very clean 1982 Mercury, 50 hp. Compression test is about 150 in all 4 cylinders. Put it in the lake today for the 1st time and it had intermittent power, never getting on plane. Brought it home and ran it with muffs. Removed coil wires one at a time and noticed no...

    Intermittent alarm

    I pulled the plug apart and removed the oil tank. I ran the boat on muffs today and the alarm went off shortly after starting. I checked the temp of the heads and they were about 82 degrees and the "bubble" water jacket was at 64 degrees; clearly not overheating, and has a good water stream...
