    Propeller stuck...

    I am working on my old '73 Mercury 402 and i ran into a problem. After a verry long sleep (>10 years), last summer i woke up this motor, changed the impellor, the ignition and the spark plugs and had a verry good time on the water. Not one problem during the whole summer.:cool: I know this motor...

On the back of the boat there are two plugs, one of them is at the lowest point in the hull, and the other is in the lowest point from the splashwell. I noticed that the plug from the...

    Mercury 402 Heavyweight

    I have a '74 Mercury 402 Thunderbold 40HP 2stroke Longtail, and i'd like to know the weight of this motor. I think my 14 Ft boat has to much weight on board, as the transom is verry low when i am not at speed. Does anyone know how heavy this motor is? What is the difference wit a 25HP 4 Stroke...

    Problem after WOT

    I have a '74 Mercury 402 and it seems to run fine at WOT. When I slow down after running it for a few minutes at WOT, it seem to stall and even almost stops when i don't open the throttle quickly. The plugs are new, and so is the switchbox. Carbs are cleaned recently, and the fuel is fresh. Any...

    Outboard climbing inboard

    It took me a lot of work to get my Mercury 402 Longtail back to life after 15 years playing dead in a barn.. Now it is running more ore less, but it seems that it does not like the water. When on the boat, forward is not a problem, but as soon as i go in reverse, it tries to climb in the boat...

    Kill switch Mercontrol

    I have a Mercury 402 with a Mercontrol controlbox. According to the laws on small boats I need to connect a Kill-switch on my motor. Do I need to pull new wires to the motor, or can i make a connection in the Mercontrol?

    Rectifier Mercury 402

    I am looking for the posibility to charche my batery on my Mercury 402 Thunderbold 40HP 2stroke. According to the electrical drawings i found, there should be two yellow wires to the rectifier. These two wires are missing on my motor, and so is the rectifier. When the motor is running, and i...

    timing on Mercury 402

    I have a 402 40HP Thunderbold and i have trouble setting the idle speed. Shouldn'd there be a second marker on the crankcase to set the ignition? There is one white line on the red flywheel, but nothing to align it with. My idle speed is about 1500 RPM in neutral, and i think this is to high...

    reverse trouble?

    I have a Mercury 402 longtail outboard, and i ran into a problem last weekend. I took the motor out for the first time, and it seemed to have some trouble running on idle. Everytime i put the motor in neutral, it just stopped. I tried to set the idle-srew on the carb, but it gave me some...

    Boat Manufacturer

    Does anyone know this type of boat? I am looking for the brand, type and year. I think it is a European build boat, but that's all i know. I could not find any numbers or other info on it. They told me it was a Cresent, but this info seems to be wrong. I contacted Cresent in Sweden, the boat was...

    fuel consumption Mercury 402 40HP

    I have a '74 Mercury 402 40HP 2stroke longtail, and i would like to know how much fuel i need for a day out. I am thinking about getting a fuel-tank from 23 Liters. Will this be big enough? I realise that there is not a solid answer for this question, because there is a big difference between...

    I have a Mercontrol control box on my 402 Merc Thunderbold. The box has an ignision-key, electr. shoke button, a shift-lever and a throttle. I noticed a plastic cap on the front-side of the controlbox. When i remove this cap, there seems to be a three-wire elctrical connector underneed. Can...
