but what do you need to do if your carbs still arnt right. i have a 1986 omc sea drive 2.6L (175) and it starts up and runs good at idle and also when out of the water, she runs great. but when under a load the motor will not get the boa tout on plane. i can idle all day long, but she just wont just out on it. what is my problem???

Normally if you rebuild the carbs and its done correctly....and it still does not work. The problem lies elsewhere.

Compression and Spark are always the place to start. There is no need wasting your time if you are looking in the wrong direction.

Once you take out the plugs you have to replace with new ones right??

I have a friend who told me that outboard motors are a lot more expensive to work on than inboard/outboards ... Is this true?

i have a problem with my 1998 johnson 2 stroke 3 cylinders i toke it to the water for the first time sense last year and i did the winterize.but start at slow speed normal but when i go to 3/4 of the throttle to full speed start to struggle it doesn't die it just keep fighting to keep going and like after 5 mnts it goes back to normal but only for 1 mnt. i empty the fuel thank and lines new fuel filter and spark plugs and toke the carbs out to take the old fuel. but nothing could be jet needle?

From one Canadian to another: Great vid!!!!! Just bought a 1973 Johnson 25hp. Runs great, but I`m going to clean the carb anyhow (not sure when it was done last). Carb kit will be in today! GREAT tips on removing/installing the little frost plugs!!!!!!! I`ve always wondered how the heck to remove them. Not familiar with boat carbs, but I do 100`s of snowmobile carbs a year, this should be a sinch!!!! Thanks for the video, very clear and precise....thumbs up!!!!!!!
