    2010 Bf150 possible fuel starving?

    Any updates? I have a 150 and replaced the head. Runs great but usually the first throttle up when it get to 4000-4500 it drops back down to 2000 then I throttle back and throttle up and it’s fine. Doesn’t do it all the time and usually only at first throttle up or after starting when it sits...

    2005 BF225 Water In Oil - Advice Needed!

    Check behind the valves for a hole. That’s where mine leaked. It looked good everywhere else, once I pulled the exhaust valves there was my hole.

    My 2009 BF 150 milky oil update

    Just an update. About 12 hours on the new cylinder head and still going ok. No hiccups yet. A lot of slow trolling cause that’s what we do on Lake Erie. I haven’t had it to wide open just yet but close. Lake has been rough every time we go out. Lol

    BF130 water in oil and questionable compression

    I just rebuilt my head on my bf150. I had milk oil as well from a rotted water jacket in the head. My compression was lower than normal when I checked but I didn’t have the throttle open all the way so that could have been the reason. I found a complete head with crankshafts, rocker arms and...

    2009 BF225 Water In #6 cylinder and the Intake Manifold After Rebuild

    Yes. I have 840 hours 2009. I would post a pic but it says the file size is too large. I’m hoping to repair then repower in a few years and go up a few hp. Good luck with your adventures.

    2009 BF225 Water In #6 cylinder and the Intake Manifold After Rebuild

    I don’t have the same engine but on my 150 I’m currently working on there was a hole or holes in the cylinder head but only visible after we removed the valves. Otherwise it looked completely normal. Like others have said I would suspect the head. U might be ok if it only locked up and didn’t...
