    Honda BF50 Overheating, Oil from Exhaust

    Was the oil inside the motor milky? Did you figure out why it wasn't peeing? Was it running fine for some time then suddenly overheated, or did it overheat as soon as you left the dock? How long was the drive back to the dock while the overheat alarm was going off? There is not enough info...

    Honda BF75L cooling water issues

    Sizzling sound is probably water boiling or steaming off somewhere. Getting it that hot risks creating new problems.

    Honda BF75L cooling water issues

    I'm not sure the answer to your question, but two things: first if you're using a descaler that actually works, you're going to want to do some serious flushing with fresh water as soon as the descaling is done. From my experience, the measurement would be in minutes, less than an hour. Strong...

    9.8 Tohatsu dies out after initial start

    I'll bet you've got a leak in a fuel line under the hood somewhere and what you're smelling is gas that leaked out, and when the motor is running air is leaking in.

    9.8 Tohatsu dies out after initial start

    It's possible if the float was sticking or the float valve had some debris stuck in it, but you put a new carburetor on it so that makes a float issue unlikely. If you think it's flooded, remove a spark plug and check if it's wet with gas.

    9.8 Tohatsu dies out after initial start

    Does squeezing the ball resolve it?

    9.8 Tohatsu dies out after initial start

    I'm with these guys, sounds like a fuel delivery problem. If there's a squeeze ball in the gas line, squeeze it and see if that temporarily resolves it. You can also open the drain screw on the carburetor bowl and check if it's full of fuel.

    Honda BF75L cooling water issues

    Sometimes if you spin the weed whacker string while you insert it, you can get it to walk around the corner then you can push it in further.

    Honda BF75L cooling water issues

    Stiff weed whacker string is stiff enough to dislodge some debris, but flexible enough to bend around corners and soft enough to hopefully not scrape up the metal. If it's a fresh water motor that is in otherwise great shape, at some point it might become worth it to remove the head and...

    Honda BF75L cooling water issues

    It's odd that a fresh water motor would clog up with mineral deposits, maybe it's something else (sand, grass, etc..)? It's also really odd the previous owner removed the thermostat, that's not normal. Do you still have the guys contact info? Maybe you can ask him why he removed it. But...

    EPA mixture screw covers 2003 BF50

    When it's running on 2 cylinders, quick open the drain on each carburetor and make sure all 3 bowls have fuel. I was out fishing one day and suddenly mine started running on 2 cylinders. I took everything apart very carefully and found a tiny piece of rubber from an old fuel line blocking the...

    Have you run it in a bucket in the past without problems?

    Honda BF75L cooling water issues

    Has it overheated ever since you owned it? If yes, I'm going to take a wild stab in the dark. How does the paint on the prop and lower unit look? If it's missing a bunch of paint, perhaps the previous owner ran it into a sand bar or similar and sucked up a bunch of sand and that could be the...

    Honda BF75L cooling water issues

    On Honda models I have seen, the above-water exhaust ports don't typically discharge any water. You should have hot water coming out the prop with the exhaust.

    Can you change a Tohatsu 9.9 hp to 20 hp?

    See if you can find anyone who has used it. Also make sure it's all OEM parts, ask the person who is selling the kit if it's OEM or aftermarket parts.

    Honda outboard BF 15

    Turn the idle screw out? Figure out why it's revving too high. Is the choke partially on? On some motors putting the choke on also opens the throttle, check if yours is like this. Did the problem just start out of the blue, or after some work was done on it?

    Can you change a Tohatsu 9.9 hp to 20 hp?

    Look up your motor and the same year 20HP on a site like Partzilla and start going through the usually suspects one by one looking for differences in part numbers. Carburetor, intake manifold, ECU, etc.. If you can get a handful that are different, then start figuring out the differences and...

    Can you change a Tohatsu 9.9 hp to 20 hp?

    We had some childhood fun with an old Firestone, the kind you wrap the rope around the top to start it. I'm not sure what horsepower it was, I'm going to guess 2-3HP range.

    Honda BF75L cooling water issues

    Remove the thermostat housing and fire it up. You'll know pretty quick if water is reaching the thermostat. Have you checked the impeller and water pump in general to be sure it's in good shape? If the thermostat is missing, I'm going to guess the previous owner had some sort of overheating...

    Hit starting wire bundle with screw.

    Thanks for letting us know the solution. Hopefully you're up and running now! Be sure to seal up those wires, if any salt gets in they're going to corrode end to end.
