Hi folks. Wonder if anyone can help before I condemn my outboard to the metal recycling skip.
I have a Honda BF2 , yes I know they’re probably the worst small outboards ever made, all my other engines are Yamaha and they’re way, way , way better. I didn’t buy it , it came with a previous boat.
anyway, this little Honda has always started and run well enough. It still does. But on the last use I noticed a rather fast drip of oil down the side of the engine. Took it home and removed the cowling and ran it in a water butt and I’ve traced the leak to be the breather pipe that sits under the recoil mechanism. strangely , the oil is virtually pouring out its dripping so fast at idle, at high rpms the leak slows to a very slow drip or even stops. Any thoughts? I’m no expert but was wondering if piston rings have gone and it’s pressurising the crank case? But then it’s such an easy starter and I put my compression tester on it and it’s got decent compression.
seems a shame to scrap it as it starts first pull and has plenty of power. It’s kind of reliable but scruffy ..so perfect to leave on an old dinghy on the foreshore when I put my boat on a mooring for a few months in the summer.
but I can’t use it streaming oil like this it will run dry of oil in a few minutes and cause an oil slick too.
grateful for any thoughts or ideas to try.
