    2016 Tohatsu 20 issues

    Agree with the above, if it started exactly when the bag incident occurred, then the water pump is a good place to start, it's possible lack of water cooked the impeller and now it's overheating and going into protect mode, if the motor has that feature. You could also start by pulling codes to...

    1995 Honda outboard BF50A carb problems

    I can back this up, I swapped the fuel screws in my 99' 50 a couple of years ago, adjusted for the best idle and haven't looked back, a huge improvement over the way it came from the factory. Edit --> I just realized you said the air adjustment. Are you referring to the screws that open the...

    Is the timing belt a known weak point on these?

    Honda BF50a milky oil…did I buy a bad motor

    That's a good bit of oil. That plastic cowling is held on by I think 2 screws. I tried to remove mine once but the screws were stuck from years in salt, but they look pretty easy to drill out if you really want to get it off. If that came from you having the valve cover off then you should...

    15HP Yamaha, 2017 era, any known weaknesses?

    I may be checking out a used 2017 Yamaha 15HP this weekend, can anyone fill me in on any potential weaknesses on this particular motor that I should look for? It is on a 12' boat that is used in salt.

    Stalls running at idle speed

    They're really fragile, I think they're designed to pop off easy, as in break the head off the screw easy. When I took them out of my motor they broke off super easy. It looks like Honda sells replacement kits for at least some motors. Check on the parts list for that specific motor, and if...

    Stalls running at idle speed

    If you can find the non-USA equivalent of that screw, or maybe a repair part for that screw, then you can replace it with an adjustable one. I did that on my 50. The head breaks off super easy, then use a left handed drill bit or easy out and the screw comes right out since it's not tight. I...

    Honda BF50a milky oil…did I buy a bad motor

    Mine will often bounce around at idle (it's obviously the tach misbehaving), but by about 1200 RPM it's working perfectly. It has been like that since the day I bought it and I guess I just learned to ignore it. If you find a way to settle it down at idle then let me know, that would be a nice...

    Honda BF50a milky oil…did I buy a bad motor

    I don't recall where mine are set, I think I started about 1.5 or 2 turns out then just adjusted for best running and never went back to check where they actually were. That said, these are fuel screws, not air screws like you see on 2-strokes. So 1.5 turns out will be leaner than 2.125 turns...

    Honda BF50a milky oil…did I buy a bad motor

    Regarding being cold blooded: I've got a 99' 50 that I bought new in 99'. When cold, give it the choke and about 1/5 throttle and it should fire right away. Pull the throttle back to keep the RPMs reasonable and bump the choke a couple of times to keep it running. It will warm up and start...

    Cool, that makes all the difference. I'm interested to see how they do.

    BRP reveals a new style of outboard, Rotax powered, horizontal crankshaft....

    It's about the air intake being below the waterline, that's the challenge. I guess my point is, I doubt we're going to see these marketed for ocean going saltwater boats.

    BRP reveals a new style of outboard, Rotax powered, horizontal crankshaft....

    They would have to put a snorkel on it for ocean use. For example, picture backing down on a fish with that motor, it would be completely submerged. I couldn't find an example on youtube with an outboard, but picture the video below but with that motor. We've done this several times in my...

    BRP reveals a new style of outboard, Rotax powered, horizontal crankshaft....

    4T outboards have been around forever, Honda started making them in 1964. I bought my Honda new in 1999, it gets year round use in salt and the 4th hour meter is reading over 500 hours, I don't know how many hours total it has as it went several years without an hour meter after the 2nd or 3rd...

    30 hp four stroke Tohatsu

    Then figure out why. Check the spark plugs, check the kill switch, and on down the line until you find the cause. But first figure out if that's the case.

    Honda 50 Ticking/Whirly Sound

    That definitely sounds like something hitting. Try your idea, paint the magnets and edges of the coils, run it for a few then look for missing paint.

    Honda BF50a milky oil…did I buy a bad motor

    First the gearbox - if the oil is milky it's got a leak. You can pressure test it to find the leak, but it might just be easier to change all the seals while you're at it. For the powerhead - it's an old motor so corrosion is definitely a concern. Odd that it had no thermostat, I wonder what...
