    Fuel pressure adapter

    I’m looking to do some testing on my 150 before selling, but can’t locate the 6mm adapter. Every kit I’ve looked at doesn’t have it, so I ended up doing the free rental from autozone. Any ideas?

    Stuck spark plug - BF150

    I have one plug that will not budge and I’m hesitant to put too much torque on it as I would end up with a sheared plug. I added PB blaster, allowed for a two day soak (tighten/loosen) sequence to get the fluid down further and still nothing. My fear is that it is cross threaded as well. 1...

    Bf 150 flush port

    Wanted to try a different look with how effective the flush port is on my 150. Images started 20 minutes after I got off the water. You can see the difference in the starboard side after about ten minutes of flushing. Port side showed no changes and stern you can catch the manifold being...

    BF150 stainless prop selection

    Hi All, I’m currently running a stainless Mirage 17P prop on my Honda 150, and turn 6000 RPMs for 39-41 mph on my center console. It seems ideal, but many of my runs are increasing in length and I prefer to have a higher cruising speed (and higher top end if possible). I cruise at 3800...

    BF150 harness/plug??

    Hi all, This one has me stumped and looking at the wiring diagram has me at a loss. I think it is for digital gauges but want to double check. It’s six wires and the pictures should help!

    Bf150 flush port - will this work?

    When I purchased this boat three years ago, the flush port was blocked and needed to be removed/cleaned/reinstalled. Fast forward to this season, and I noticed a small leak at the junction. So, go to remove the bolt and off goes the head. Add in left hand drill bits increasing in size then go...

    Kill switch connextion

    Just when I thought I had no other projects to do, the world of boating has given me a new one. Honda BF150A6. Kill switch does nothing (don’t need it in to start, pulling it does not kill motor) There are two black wires coming from the kill switch with pigtail leads (taped). From the...

    Outboard to Bluetooth??

    Hi all, I may be looking in the wrong places so far, but does Honda have a similar product to Mercury’s vessel view, which plugs into the outboard and allows for real time data into your smartphone? Thanks!

    Lower unit dilemma

    Looking to winterize this week, however I want to repaint the bottom of the skeg before spring. I may also do the lower unit seals depending on fluid condition. My dilemma is if I should remove the LU to do this work in my basement this winter or not. I’ve seen outboards with the LU removed...

    Tube Set, Oil - BF150

    Quick question—-what is the role of this part (part 22 on the diagram) referred to as the “tube set, oil”? I see it connects to the head cover and then to what looks like the oil pan. Thanks!!

    Honda voltage gauge

    2006 Honda bf150 fuel filters and water separator

    Hello, I am having trouble understanding the removal of the two filters/bowls that have the suspension straps on them. Do I need to remove the strap prior to the bowls? I got a bad tank of gas and need to rectify all the mess. Thanks!!!

    Bf150 prop washer

    I thought everything was good to go until I checked my propeller yesterday. I either misplaced the washer last fall, or it just never had one in front of the castle nut. I picked one up yesterday, but it does not fit with the mercury mirage stainless prop (I cant access the hole for the cotter...

    Honda BF150 mid shaft bushing

    Hi All, After some reading it looks like this little $20 maintenance item can cause quite a problem if it isnt addressed based on the online horror stories. I do not believe it has been replaced (motor is an 06). The frustrating part is I did the water pump last year, so I need to drop the LU...

    BF150 Fuel Flow Sensor

    Hi All, I have an 06 BF150 that I would like to add a fuel flow sensor onto. I have an old fish finder that I would like to replace with a gps/ff combo that can also read this sensor. From what I have read, there is no way to hook up a new gps/ff to my engine as it is two years before that is...

Ive gone through dozens of threads, owners manual, and service manual, but are there any additional tricks or procedures you...

    Spare emergency parts

    I apologize if this has been hashed out before, but could not find it. Within reason, what spare parts do you carry for your Honda outboard? Prop? Fuel filters? Tstats? O2 sensor? Temp sensor? Key? Kill switch lanyard? I wonder how much is overkill, even when having a Seatow/BoatUS available.

    The drivers side bolt snapped at some point, but luckily the spring was held in with the broken bolts! Replaced the bolt today, but I do not like the looks of things in terms of support. On the opposite side, similar issue...picture describes it all. Basically, new springs were put in last...

    LED Indicator Lights

    Does anyone have ideas on replacing the small red indicator lights on a large panel? Some of them work, while others do not. I know for a fact the device works connected to it (i.e. master power, bilge, etc.) but the little red light not working is annoyong! They seem to be held in with large...
