    Honda 150 hp BAPJ crank/no crank

    A wire cable that is rusted inside its plastic case will do this, caused by an invisible hole in the plastic. The voltage drop rest should find it

    Honda BF50A Trouble restarting after running great for hours

    The filter feeding the engines from the tank is likely a water separator, spin on. Anytime you check it, drain it’s contents in a clear container to check for water or dirt. Many running issues are caused by fuel being old or full of water or dirt. In addition, using a fuel additive like sea...

    2002 BF225A chokes over 4000 rpm after several hrs of running

    That qualifies as bad.😁

    2002 BF225A chokes over 4000 rpm after several hrs of running

    Are you still going to run it on a portable tank with a good load of sea foam? Honey coloured gas is likely not good gas.

    2004 Honda 150 vtec VST drain location

    A crushed filter would seem like a source of fuel flow restrictions. Bad quality filter? Wrong filter? Too much fuel pressure? Wrong pump?

    2002 BF225A chokes over 4000 rpm after several hrs of running

    Did you check your filters, the old ones and the new ones? Cloudy fuel was likely really bad fuel. Run a portable tank with sea foam for at least 1 tank or 2 at say 3000 rpm or higher, see if that improves anything.

    2004 Honda 150 vtec VST drain location

    You should get the Honda factory manual for your outboard, don’t bother with anything but the Honda manual. My pet peeve with boats/outboards when they are not running well is fuel tank/fuel contaminants. How old is your fuel in the boat’s tank? When you changed fuel filters, how dirty were...

    2002 BF225A chokes over 4000 rpm after several hrs of running

    Did you drain the boat fuel tank and clean it out? I’m thinking a fuel tank sitting around that many years could have contamination. Do you have an external water fuel separator filter- check that and see if the filter is clean. Drain the filter into a clear container and also cut the filter...

    Inductive Tach Setting for Honda BF25D

    Try it on both settings, see which seems correct? I’m thinking idle is around 700 rpm give or take, see what number you are getting?

    BF 9.9 Dies soon after starting

    Do what Jgmo says, he knows these small Hondas very well. I’d say based on the speed of the outboard shutdown, it may not be an overheat. On a vinegar flush, yes you need the engine running in a barrel. I used about 4 jugs of food grade vinegar in a barrel, ran the outboard at 2000 rpm for a...

    Wanted Honda Vertical Shaft 41112-ZV4-750

    Check Yumbo too, they only sell OE parts, they are in Japan. Sometimes they have old parts availability for items showing as discontinued by local dealers.

    Honda 225 jerking and choppy while trimming down

    My 1999 owners manual specifies the fluid, I don’t worry about the brand. I use the same stuff in my 1963 Pontiac power steering. It’s not a high stress usage.

    Honda BF150 erratic running at high RPM

    20 hours a year since new- how big a fuel tank are you running? Could be an old fuel issue? Did you find anything dirt or water wise in your fuel water separator or the filters you changed?

    Honda 200 HP shuts down after 10 minutes of slow trolling

    The shop manual from Honda may have a good troubleshooting section on this, get the one for your engine.

    Honda BF135a Overheating if we go over 4k RPM

    Have you replaced the water pump recently with a new impeller etc? Is the outboard pumping lots of water through the telltale?

    Honda 225 jerking and choppy while trimming down

    You’ll need the same type oil/fluid the mechanic used to bleed the system, it’s easy to do. I use a long necked oil squirt can and my 1999 Honda calls for the pink power steering fluid, I used a GM spec available just about anywhere. Cycle the engine all the way up, remove fill screw, squirt...

    Running issue with 2008 BF225 with 1000 hours.

    And a valve adjustment may correct the cold idle problem.

    Running issue with 2008 BF225 with 1000 hours.

    I’m not a serious engine rebuilder mechanic, just read stuff that I retain randomly. If you have good compression, but you are burning oil, would a treatment with Yamaha ring free help? Your plugs- are they all similarly appearing, or does the one with a bit lower compression look worse...

    BF90D overheating at WOT

    I find AI is good for common problems with common issues. It’s a generic checklist of things to check. I worked on a Clarke Troller once, nothing in AI for it.😁
