    BF225A4 - Water Pressure Specifications

    What are normal water pressures for a Honda 225 at cruise and WOT? I finally got through going through all my pressure relief valves on my two 225s and getting them into shape--one was stuck partly open on one engine (which had head problems discussed in another thread here) and on the other...

    BF225 Help Locating Fuel Rail Screen

    I'm trying to figure out where the fuel filter mesh, 16614-P5G-003, is. I can't find an explanation in the shop manual. From the parts diagram, it appears to be on the port side near the fuel pressure regulator. Do I need to remove the intake manifold to get to it?

    BF225A4 - Cranking but not Starting

    My engines were removed from my boat for a few months over the winter as I had some transom work done. The engines were re-rigged after the transom repairs were complete and now one will crank, but will not start. I confirmed I have spark. My problem is fuel. My fuel pump does not turn on...

    BF225A4 - Overheat When Getting on Plane The First Time

    So, I've got a relatively minor, but strange issue with one of my 2004 225s overheating in a very specific situation. When I launch, idle out of the marina, then get on plane, I get an overheat alarm when at around 3,000 rpm as I get it up on plane. If I turn off the motor, restart, then try...

    BF225A54 - Timing Belt Tension Instructions Question

    Starting a new thread on this issue. This is probably a stupid question, but I'm having difficulty understanding the Shop Manual's timing belt tension procedure at 3-23. "Rotate the crankshaft pulley counterclockwise by six teeth of the timing belt driven pulley gear, then return the...

    BF225A4 - Whining Noise Primarily at Idle

    All, One of my 225s makes a whining noise primarily at idle, or low RPM. At higher RPM, the noise gets quieter or just gets overcome by the engine noise. I can't hear it at all at cruise. I used a stethoscope to try to find the source, and it sounded like it was at the gearcase/mid-shaft...

    225A4 - Where is this screw/part in the parts diagram?

    I slightly stripped part of the head of a screw when changing my high pressure fuel filter. The screw has enough left for me to turn it and tighten it, but I imagine it will be a problem down the line so I want to replace it. But I can't find it on any parts diagram. It's the screw that goes...

    BF225A4 - No "Beep Beep" when key is turned, but engine starts

    When I turn the key to start one of my BF225A4s, I do not get the "beep beep" and the lights do not turn on. But the engine starts and runs fine. The green light then turns on when I'm running. I'm assuming this has to be an issue with the ignition switch. It's the ignition switch for the...

    BF225A4 - Mid-Shaft Bushing Destroyed but No Damage to Mid-section?

    So... I replaced the mid-shaft bearings on both of my 2004 BF 225s. On one of the engines, the bearing was completely destroyed--I only found half of the brass portion. See photo below. I just brushed out all the corrosion in the mid-section where it goes so I could fit the new one in...

    BF225a4 - Flush Port Problems - What is this Allen Bolt?

    I've got a BF225a4 and the flush port doesn't work. I've flushed from every direction--through thermostats through the pisser port, etc. to try to remove the blockage. Water flows everywhere except the flush port. It all looks clean inside the engine looking into the hole for the thermostat...

    Lower Unit Oil Leak and Seal Kit Question for BF225a4

    All, I have new-to-me twin BF225A4 engines. They have been sitting up for a few months. After visiting my boat this weekend to do some cleaning, I noticed that there were a few drops of lower unit oil at the bottom of my skeg on one motor. After tilting the engine up and looking more closely...
