    1990 NISSAN NS9.9B2

    Unless it's corroded, a new carburetor is likely not needed. For a proper cleaning you have to take it apart. Use the little tube to shoot cleaner and compressed air through every hole, especially the small ones (wear googles). Putting the disassembled carb in a hot ultrasonic cleaner for a...

    3.4 gall honda fuel tank fitting

    If it's just leaky and you can't find the part, you might be able to extract any o-rings inside and just buy replacement o-rings. If you have a local Ace Hardware (or good hardware store) check there. Our local Ace has a pile of different o-rings. You can measure with a caliper.

    1996 BF50 Honda Bogging out when trying to plane

    Excellent! Please report back and let us know how it goes. It's amazing how much crap comes out with a proper descaling rise isn't it! My motor was the same. I flush the heck out of it, usually 15 min on the muffs while I scrub the rest of the boat, but apparently not all of it comes out...

    1996 BF50 Honda Bogging out when trying to plane

    A few things; the Barnacle Buster is going to be exponentially stronger than vinegar, no need to bother with the vinegar. After you're done with the chemical flush, flush the heck out of it with clean water to get all the chemicals out, you don't want to leave that sitting in there. To flush...

    1996 BF50 Honda Bogging out when trying to plane

    Any acid will be rough on anodes. Acids take electrons and anodes give electrons, that's why they interact so actively. I left my anodes in, mostly because after 20 years in salt I thought trying to take them out was going to do more damage (broken bolts, etc..). If the sand is packed in...

    1996 BF50 Honda Bogging out when trying to plane

    One bottle was more than enough, I think I used a little more than half the bottle. We have muriatic acid for the pool and Rydlyme is not the same. I couldn't tell you chemically what's different, but they behave different right from the moment you open the bottle. I understand not wanting...

    1996 BF50 Honda Bogging out when trying to plane

    I did not know these older motors had a limp mode!? You've got the right idea, but the wrong approach IMHO. I did a lot of research before descaling my own motor. Long story short, strait acid is going to be really rough on the metal in the engine, including the anodes. A buffered acid will...

    I have a BF15 HP Honda with a Power Prooblem.

    Easy things first, does the throttle plate open fully when you give it full throttle? Also did you double check the shop to make sure they gave you the correct carburetor? Maybe compare to the old one if you still have it, to see if the new one is smaller. Also is that a 2 cylinder motor? If...

    I have a BF15 HP Honda with a Power Prooblem.

    Are you sure the correct OEM carburetor was used? If yes, it should be jetted correctly right out of the box. If an aftermarket carburetor was used then all bets are off.

    2.5HP Mercury/Tohatsu/Nissan Outboard No Longer Starting

    Not knowing how much you took it apart, did you put the reeds back in properly? While waiting for the compression gauge to arrive, treat it like it's flooded and see if that helps. Remove the spark plug, be sure the spark plug is grounded or the run switch is off (to keep the electronics...

    MFS 9.8 rusty

    boats.net has parts, but I don't know what it costs to ship to Italy. Tohatsu sells around the world, there must be a dealer in Italy somewhere. If you use the motor in salt, spray everything under the hood with silicone spray when you're done for the day. The silicone won't hurt the rubber...

    MFS 9.8 rusty

    I'm going to attempt to translate. The bottom bolt is rusty and he would like to replace it. Why are there numbers on the bolts and what do they mean? Answer: I believe the number "7" on the bolt refers to the grade, or strength of the bolt. Find another bolt with the same marking. Or you...

    2002 25 hp rebuild

    Great, hopefully it will work. Not knowing which sealant you used, I'm hopeful you chose one for engines that will be tolerant of gas and oil.

    You're going to need to disassemble to seal it correctly.
