    How to install a Fuel Pressure Gauge on your 3.5 v6 Honda outboard BF225

    OK this may work for other models as well the BF225 but I cannot confirm. This is IMO a needed item when it comes to trouble shooting problems with your outboard. Nearly 218% of BF225 engine trouble boils down to fuel delivery in some form or another. The other 43% will be "other" things...

    Fuel Pumps for the 3.5l V6 Honda outboards - High Pressure Fuel Pumps $54.99

    Guys I cringe every time I read a post that involves replacing these overpriced $200 fuel pumps. You can buy the pumps from Autozone part number 5211009 for $54.99. I've been using them since they were $47.99 about 5 years ago. I replaced the pumps in my 2002 BF225's and they haven't missed a...

    2002 BF225 RPMs and Power dropping off under load

    OK guys one of my twins has decided to be a problem child. It runs fine in neutral up to 6000 + RPMs. In gear it'll only go up to 3000 before it starts coughing and bucking. It has to be under load to do this. If I bring the other engine up to 4000 rpms first I can get the "problem child" to...

    Ok so I'm having to chase a problem and I have the chance to change my fuel pick up tube. The current tube is 5/16" Stainless tubing. Is this adequate? I installed it out of necessity at the time but I have the chance to correct it if it is to small. What size does a pair of these engines call...

    BF225 Fuel Injectors interchangeable?

    Look at the Accord fuel injector. Looks like Honda may have done this to eliminate carrying multiple parts that can serve the same duties. I'd like to get the specs on the Accord and BF225 injectors to see if they are the same. Accord injectors go for $33 NEW.

    I know the replacements look a hellofa lot the standard Honda Civic Fuel Injectors that can be had for $22 + core. It would be IDENTICAL in appearance if it had a longer discharge collar.

    BF225 Fuel Injectors interchangeable?

    Has Honda changed the fuel injectors used on the BF225s during their production run? I received and installed an injector that was marked differently from the one it was ordered to replace. The fuel injector related miss has vanished and the engine is running like new since I installed the...

    So I just noticed that the flappers that are on the inside of the intake manifold cover are stuck open. By design they should open and close with vacuum but mine are stuck open. What problems would this cause? Its the flappers that are on the inside of #4 in the diagram...
