20 Most Recent Honda outboard Questions & Answers

Hello, everyone.
The engine is generally healthy and what bugs me the most, has JUST been overhauled by a good mechanic, which included cleaning the carb, after which it started on 1-3 pulls and ran like magic.
Today I went fishing for the first time after not using the boat for about 3 weeks. The engine started fine (with 2/3 choke), I let it warm up a bit, with little-to-none choke. Idle was a tiny bit rough, but nothing major. When I set it on idle for the first time, it ran for about 3 minutes and died. Since then I could only start it with either choke or some throttle and it'd always die quite soon on idle or close to idle. When I try to start it warm with no choke, it'd sound as if it catches and dies off immediately.
The plugs are 1 month old and adjusted, oil's in order, no detectable problems with the prop or anything else.

I have a suspicion it might be either condensate or some grit in the fuel tank, which was stored in a rather damp place for 3 weeks, half full (although tightly closed). What should I check and is there a way to condition the fuel somehow to remove condensate and clean out eventual b/s from the carb without major mechanical work (I really don't want to pull the boat ashore before autumn)?

Thank you!

Hi there. The tips are generic and may or may not apply! 1)Does it have points with capacitor? It can be burnt or dirty.2) Check the cable feeding the sparkplug loose or cracked? 3) Remove the wires to your kill switch at the engine and try to start if it starts then with your ohm meter check switch working and wires for breaks or short circuits

Not the carbs, not the fuel pumps, maybe the fuel delivery volumes to the carbs by the fuel pumps. A restriction can cause the engine to suck the carburators fuel bowls dry if not enough volume of fuel is delivered. Do a fuel volume test

i would look for a leak in a fuel line or connection or a needle that is stuck open flooding that carb which will sometimes run out of the front of the carb and into the base of the cover. when the air intake cover is on you cant see this happen.

you probably have either a bad capacitor or more likely a short stator winding due to previous overloading

Verify that the double gang circuit breaker is good on both sides. Check for loose wire on breaker or receptacle.

If it's on a Ryobi Generator then it should be a real Honda Engine. It's possible that it's a knock off or was replaced with one. If you bought it new from a reputable source then it's real, if it's used or came from an offshore source for a really low price then it's a good possibility that it's a kkoxk off. In all honesty, from my experience they do a great job with the knock off engines & they're usually reliable and last a normal life span similar to a real name brand.

Either way, that mechanical Issue Remains, I'm assuming you're refering to the valve being stuck and basically keeping the engine locked up and not allowing it to the over when attempting to start it. Sounds likely. Did you take the spark plug out and turn it over to see if it'll turn over at all to ensure it's not just totally locked up? My suggestion would be to Remove the valve cover and spark plug so that you can see the valvetrain in action when(if so) it is turning over and observe it to see if your valve theory is correct!

Thanks and good luck my friend, see the infinity below please, have a great day!

The reduced atmospheric pressure at high altitude means the standard carburettor settings will not allow sufficient fuel to flow for efficient running.
The dealer or manufacturer should be able to provide details of alternative settings - the jet sizes are usually increased a few points for every 5000 ft above sea level.
The cooler temperatures experienced at high altitude would probably change the engine oil specification to a lighter or thinner grade.
