    Is Honda Marine Grease Compatible with Lithium Based Marine Lube?

    The shop manual for my BF250D says to use water resistant urea based grease for most of the lubrication points and zerk fittings. Does this mean that Honda Marine grease is a polyurea based lubricant? This type of grease in not compatible with other lithium based marine lubes. When you mix...

    Flush Hose Attachment Point BF250D

    I'm embarrassed to ask such a dumb question, but the flush hose pulled out of my motor and I can't figure out where it attaches to the cooling jacket or block. I can't even see how it can pass through the cowling. Nothing I can find in the shop manual shows where it is connected. Please help...

    Dark Oil in BF250D

    I just had my marina do the first 100 hr service on my BF250D. They told me that the oil was very black. Dark enough for them to take note of it. I did the 20 hr service myself and the oil was clear. Barely able to read the level on the dipstick. So something must have happened over the next...

    ECO Light on HD-4 G gauge

    Does anyone know what the ECO light on the HD-4 gauge is about? I thought that it had something to do with when the variable valve timing shifts over. But depending on sea conditions it seems to turn on even at pretty high rpm. See below: Edit: It may not be clear from this image, but the...

    Removing Cover on Honda Top Mount Control Box

    BH250D Vacuum Leak?

    I just did the 20 hr service on my new BH250D. It surges a bit at idle and when I listened to it with the hood off I hear a sucking sound. It gets very loud when I shut the engine down. I hope that you can hear it in this video. Is this normal or do I have a vacuum leak?

    Newer Honda BF250 Question

    I'm considering repowering with a Honda or Tahatu 250 hp engine. I've been told by a dealer that Honda has made some changes in the 2018/19 model year that includes the elimination of oxygen sensors. While I know that these have been problematic in the marine environment, I'm concerned that the...

    Testing BF50 Overheat Switch, Horn, and Warning Light

    A friend of mine picked up an older BF50 that appears to have been assembled from parts taken from several different engines. While it runs well, we found several wires disconnected from the harness both at the engine and the control unit. We would like to test the overheat warning mechanism...

    Draining Vapor Separator Tank on DF40

    "I need to store my engine for "I need to store my engine for several months so I have gone through the usual winterizing procedures (fuel stabilizer, changed fluids, fogged the cylinders). But I don't see any reference to draining the VST in either the owner's or shop manual. I thought that...
