    BF5A revs up then wants to die after throttling up or closing choke

    Title says it. At first, the engine would start but couldn't maintain idle, so I cleaned the carb, replaced failing parts, and inspected all jets/passages. Replaced/cleaned fuel system components and fuel lines. Now the engine will idle, but wants to die out after throttling up or closing the...

    BF30A Bogging under load mid to high RPM

    Engine is a BF30A 1997. Bogging only happens under load; when not in gear the engine will rev up to the limiter just fine no issues. When under load the engine will rev to mid rpm no problem, but as soon as I give it the beans it just bogs down and won't put out any more power. Sounds like the...

    Hey guys, you've saved me with this engine in the past (BF30A LHSA pre-1997), and I'm hoping you brilliant people will do it again, cause I'm all out of ideas. Let me give you the run down. I would say this engine started having suspicious problems about a week ago, 2 trips before the engine...

    BF30A - Reasons for sudden weak telltale?

    My motor is a BF30A LHSA pre-1997 with over 3000 hours on it. The telltale usually runs very strong, but recently, it is running quite weak. I will add that the transition from strong to weak was very sudden. At the beginning of a fishing trip it was strong, and at the end, it was weak. I have...

    Stuck Choke? Honda 30

    Hey guys, I've been having some issues with my Honda Bf30A. After coming back from a fishing trip not too long ago, the motor was idling really high. Not sure if this was related, but that same day I found out that my lower unit oil seals were compromised, and that the oil mixed with water. I...

Yeah, the motor eventually sucked up enough water to put the water level below the cavitation plate, and sucked air for a...

    BF30A Oil pressure light questions

    Couldn't find any helpful info online so I figured I'd ask you guys. My green oil pressure light has been behaving interestingly. Ever since I bought this motor, the oil pressure light would flicker green at all times when the motor was running; I noticed it would flicker green faster at higher...

    BF30 loud clicking noise from flywheel

    Hey all, I have recently noticed a loud clicking noise coming from what seems like the flywheel area of my motor. The noise started after I heard a loud CLUNK come from the lower unit (maybe the prop) of my motor while I was putting my boat back on the trailer in the harbor. It seems to sound...

    Hey guys, I'm not sure if this is actually a problem or not, but my bf30a Honda outboard seems to be overheating. After running for only about 10 minutes the lower unit and engine block are both too hot to touch for more than a few seconds. Not sure if this qualifies as overheating, or even if...

    After following all the procedures in the SELOC manual to replace the timing belt on my BF30A Honda outboard, the motor does not start.

    Just so you guys know, I am very new to boating and working on outboards. My BF30A Honda outboard has a small tear in the timing belt. It still runs fine and I have used it several times since I noticed the tear; the tear has not gotten any bigger. I am curious as if it is safe to continue to...
