    Starter plunger

    I tested the heating element inside with 12V and it got hot right away. Then I reassembled it tested again to se if the needle would move but it didn't. It was difficult to sense any heat from the ouside of the plastic body. There is a rod inside the "wax" chamber and when I pulled it out I saw...

    What are these Yamaha parts?

    On my Yamaha F9.9BM 6G9 S 008982 Z (1994) engine there are two canisters I can't identify. What are they?

    Yamaha 9.9 stalling

    I rebuilt the carburetor of my Yamaha F9.9BM (6G9 S 008982 Z 1994). It starts really easy but sounds like it's running on one cylinder and when I throttle up the slighest it stalls. I ran it again, wihout hood and when I put my thumb close to the carb intake it reved up. It seems like my thumb...

    Are the variants interchangeable?

    What are those numbers?

    For my Yamaha 30DEO 6J8 L 455099 G (=1988) the lower end casing should be 6J8-45300-14-EK (I think). I've found one casing numbered 6J8-45300-10-EK. What are those extra "14-EK" and "10-EK"?

    Yamaha pulling outboard bearing carrier

    This YouTube video shows how to pull the bearing carrier. One thing that isn't shown is that, as I believe, the gear selector has to be removed first. Am I right here or not? If the gear selector needs to be removed first, what do I do if it is, as in my case, stuck and can't be moved?

    Yamaha 9.9 1984 in the water

    My Yamaha 9.9 was submerged in water (almost fresh) for 24 hours. I took it home, removed the plugs, sprayed cylinders with oil, emptied and refilled the engine and gear-house oil. I then put it in the sauna at 60°C for six hours. Not being able to start it I removed the carburetor and cleaned...

    Yamaha 25 hp leaking oil

    Yamaha 25 hp 30DEO 1988. I filled the lower unit with gear oil today and found that a lot was pouring out of the holes seen in the photo. What are those holes anyway and why are they leaking oil?

    Yamaha 25hp shift rod stuck

    My boat with Yamaha 25hp was left outside for a year and I took it home to look it over and run it. I couldn't move the gear shift lever so I removed the lower part and found that the shift rod is stuck. I can turn the propeller but not move the shift rod i any direction. I guess I have to take...

    Evinrude 15hp no start.

    I finally purchased new ignition cables and with the spark tester I get good solid sparks 3/8" long so that was perhaps part of the problem. I have replaced the fuel line both inlet-to-fuel pump and fuel pump-to-carburetor with transparent hoses so I can see how far the fuel gets when I press...

    Evinrude 15hp no start.

    I bought a spark tester and while I was spinning the flywheel wathcing the spark gap I discovered a big, fat spark going from the ignition cable boot to the block. I guess it means new set of ignition wires.

    What year Yamaha?

    I just purchased a Yamaha 15hp 4-stroke outboard motor. I can't find the info when it was manufactured. I don't find the info conclusive. some say the bottom right letter (Z) is the year code and that would mean either 1973 or 1994, others say it's the last letter in the model name (M) which I...

    Evinrude 15hp no start.

    Thanks racerone Tested the plugs again for sparks. Watch the video clip. I think the spark looks good enough but I also know that plugs can produce good sparks in free air. When they come under cylinder pressure they may not. The next thing is the spark plug wires. I've already measured them to...

    Evinrude 15hp no start.

    I removed and disassembled the fuel pump and it looked fine. I saw a hole at the back of it and another in the mating surface of the block. Something moves the diafragm in the pump, so is it a piece of rod or the engine compression that is routed through this hole? If the pump doesn't work...
