    Honda 9.9 burning oil

    The crank case breather might be run to the airbox, that's common on 4-strokes. Some ideas to check: if the oil is too full, it can pass oil through the breather to the airbox. If the motor was stored in the wrong position (laying on the wrong side) oil can get into the breather and into the...

    Frequent gunk in 1994 Honda 9.9 carb

    If you're using ethanol gas, that's your problem. Use non-ethanol gas (usually called Rec90 or Rec89), use stabilizer, and drain the carburetor empty if its' going to sit more than a week without use. Don't just run it dry, that's not really "dry", use the drain plug on the carburetor. Do not...

    50HP fuel connector - where to buy?

    Thanks I might have to give that a try. It doesn't say the year, and I've noticed for whatever reason the one that fits my year has been difficult to find, but for $10 maybe it's worth a try.

    BF15DK2 production year/value estimate from model/serial #

    Sea trial is the best way, see it run on a boat. As mentioned above, a motor can appear to run perfectly in a bucket, but actually run horribly on a boat. Also with boat motors there's no real hours/years metric as the condition will depend almost entirely on how well it was cared for...

    BF25D won't get above 1600 RPM

    Wow I can't believe it's already getting cool somewhere, it's still in the 80's here (S. FL). That said; really odd that it won't rev but is smooth. My first guess was going to be too much prop, but if it only revs to 2200 in neutral then it's something else for sure. Does it "sound" like its...

    50HP fuel connector - where to buy?

    I need the female side (fuel tank side) fuel connector for my 1999 50HP Honda. The part number for both sides (fuel line side and motor side) is 04104-ZW9-010, but it's $43 and I don't need both halves, I only need the fuel line side. Does anyone know where I can get the OEM part for the fuel...

    Honda Bf15a has cover with "2006" stated but not sure of year

    Does the cover says 2006 emissions compliant by chance? My 99' Honda had a sticker on the cover boasting about being emissions compliant for some future year, I don't remember which year.

    Broken Thermostat Housing Bolt

    We were typing at the same time! Are you the one who suggested the center drill to me several months ago for my BF50 exhaust plate issue? It worked fantastic.

    Broken Thermostat Housing Bolt

    Drill, tap and insert a helicoil or time-cert. There are kits online that include the drill bit and insertion tools. If it's broken below the surface, measure the size of the hole with a caliper and get a center-drill with an outer diameter the same size as the hole. Search Harbor Freight for...

    Excellent great job!

    1998 honda 75 hp completely dead

    My first thought is check the cam timing. Check the ignition timing too if it's adjustable. Also check the valve clearances and compression or leak-down test, with the goal being to figure out if any intake valves are leaking. Lastly, you've got it out of the water but in gear and revving...

    Hard to synchonise Honda BF50A - 98

    Did you clean the insides of the carburetors, in particular where the butterfly valves close against the carburetor? If not, then check that first. Once that's clean, use the adjustments on the linkage between carburetors to get them all balanced. If you haven't been adjusting those, then...

    Help please tohatsu 6hp

    If it does not run on the internal tank, and you have to continually squeeze the ball when on the external tank, then the fuel pump would definitely be on the suspect list. What happens if you use the external tank and ball to prime the carburetor, then switch to the internal tank? Does it...

    Help please tohatsu 6hp

    Based on my experience with my 2014 Tohatsu 6HP (probably the same as yours): If you're using the external tank, you do not need to open the vent on the internal tank. Turn off the internal tank and unplug the external hose before laying it over for transport. It will transport just fine if...

    1996 BF50 Honda Bogging out when trying to plane

    Excellent job sticking with it, hopefully it will run for a very long time. :)

    1998 honda 75 hp completely dead

    My first guess is, that looks like the trim angle sensor. What it's doing under the hood is anybody's guess.

    1998 honda 75 hp completely dead

    Start at the starter solenoid. Does it get the 12V signal when you turn the key? If no, the work backwards towards the key. If yes, does it supply 12V to the starter (check the big wire on the starter)? If no, maybe the solenoid is bad. If yes, the starter may be bad.

    Gas and Ethanol

    Don't bother trying to remove the ethanol from gas, it's not worth the effort. Your motor will run OK on the ethanol, it's just not good for storage. Stabil brand stabilizer seems to work good for me. My little Tohatsu 6HP only gets used a couple of times a year. All I do is drain the carb...

    Can't prime my fuel line

    If it's staying squished then it can't suck fuel from the tank. Something is obstructing the flow. Check everything between the squeeze bulb and the tank, and make sure the vent is open on the tank if it has a closable vent. If there is a fuel filter or fuel/water separator between the bulb...

    Tohatsu 9.8 hp oil recommendations

    Quicksilver is Mercury's brand, it's typically decent quality. Just check the spec on the bottle against the spec in the motor manual. If the specs match then you're fine. You don't need specifically "marine" engine oil, if the specs match then you're good. I've been using that gear oil in...
