    200 hp stalling

    First up try cleaning out the IAC valve located right on top at the back of the motor on the starboard side. It had a gauze screen which gets blocked, use some throttle body cleaner or similar and compressed air to clean it.

    1200hr service on BF225

    Yes, it's the dumbest thing Honda's ever done, put the commercial maintenance costs past astronomical. It's a big job but now they're there they must be done or problems with corrosion will be worse than before because of the screw that retains them

    Honda 225 Outboard Ignition Issues - Won't Start

    Have you got a workshop manual? If not you can download the factory manual for free, just google Honda BF225 service manual and look for it. That will give you a proper troubleshooting guide. It's very difficult to talk you through it.

    1200hr service on BF225

    No need for that, normal service plus all internal anodes. You don't do injectors, timing belt only if necessary, check for cracked ribbing. What year is your motor? If younger that 2013 the powerhead needs to come off to replace anodes on the lower water gallery.

    Honda 225 Outboard Ignition Issues - Won't Start

    You need a wiring diagram and a voltage drop test, a good auto electrician would fix this easily if you don't have the knowledge to do this.It is definitely low voltage but the problem could be anywhere between the battery and efi power supply.

    I'm getting frustrated. Hard Start.

    What happens when you put the seemingly faulty starter on the other engine? It could be drawing slightly more and you have a voltage drop across the isolator. This is why the fit up manual states the smaller positive wire must be connected to the battery, not the isolator.

    One more question, where is the smaller pos battery lead connect?

    Don't worry, that screen troubles most people struggle, there's a trick to them using a thin blade screwdriver to release the clips. I feel your frustration with tis motor. If all your efforts with the VST fail, try checking spark on innitial crank, if spark is good then remove the plennum and...

    I'm getting frustrated. Hard Start.

    Just try something, try turn the ignition on then off after fuel pump has cycled without starting the engine, do this about 4 times then try starting and see what happens. If the fuel system is losing prime then it should start using this procedure. If this fails, try swopping the O2 sensors...

    2010 BF50D Fuel Pump issue

    Thought you said you had serviced the injectors, I'm guessing now you did the youtube clean, not a fan of that, espeacially when they are playing up as a result of stale fuel. A sonic clean would fix them but go ahead a buy new one's , they'll make a big difference. Also just in case, make sure...

    1997 HONDA BF50a RUNNING DETERIORATING AFTER 5 MINUTES !!

    Just to add to this, tie the boat up well on a dock and do all these tests at the dock with motor running under moderate load.Do a cylinder drop test too while you're about it. If a cylinder is dropping in and out then when offending cylinder is disconnected, the revs should remain constant with...

    1997 HONDA BF50a RUNNING DETERIORATING AFTER 5 MINUTES !!

    Testing a cdi with a resistance test in my opinion is the worst test there is. Mercury recommend a dva meter and test voltage output with the engine running. You should get around 5 volts from each trigger coil (I have known a few of these to fail), and a min of 100 volts at the terminal into...

    Do your valve clearance, it's quick and easy and it will improve idle quality. Intake 010" ex 12"

    1997 HONDA BF50a RUNNING DETERIORATING AFTER 5 MINUTES !!

    Try pulling one plug lead off at a time, if one cylinder is playing up you will be able to identify it, that should be your starting point
