20 Most Recent Honda outboard Questions & Answers

The carburator needs to be cleaned, the idle jet is the first one that stops up. Make sure that the oil is up to the level and fresh and make sure that you have a clean tank with fresh fuel. You could do a Californian carb clean: rev it up and put your hand over the intake to create a vacuum till it almost stops and do that a couple of times, the jet could clear up in mild cases.

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

Type Honda, the model number of your motor, customer service into your computer search engine. It will being up Honda customer service web sites you can contact and ask for info.

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.

Maybe you can ask your supplier to get the wiring diagram

Check oil alert switch, ignition switch and connections.

For your question, i have replied many people, why generator set can start but not generate electricity?
Here is some reasons for reference:
1.After the diesel generator is stopped, the residual magnetism is often lost, because the material used for the magnetic pole of the exciter is close to the soft steel, and the residual magnetism is small. After the shutdown, when there is no current in the excitation winding, the magnetic field will disappear.
2.The magnetic pole of the diesel generator loses its magnetic properties.
3.Damage of excitation circuit components or circuit breakage, short circuit or grounding phenomena.
4.The exciter brush is not in good contact with the commutator and pressure of brush holder is insufficient.
5.Excitation winding wiring error, opposite polarity.
6.Stator winding and rotor winding of generator set open circuit.
7.Poor contact between diesel generator brush and slip ring, or insufficient brush pressure.
8.Diesel generator lead wire wiring is loose or switch contact is poor.
9.The fuse box is fused.
10.The "auto-manual-de-excitation" switch on the control panel is in the de-excitation position (automatic generator set has "auto-manual-de-excitation" switch).
11.The voltmeter is damaged.
12.Rotary rectifier module is damaged.

Most of the time it is either the Capacitor or AVR that has blown (depending on what is fitted on your generator.). Check out our videos on how to test them.

I think there is overload .kindly measure ur load of consumption. Do not run the generator set with high load it can be cause of circuit breaker Tripp off .

Honda Electrical... | Answered on Jul 27, 2019

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

Honda Electrical... | Answered on Jun 03, 2019

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