Without seeing it it’s hard to pinpoint exactly what the issue is. It’s possible it’s not getting enough fuel, I would check the lines and the jets in the carburetor. Or, it could be something as simple the choke not being set right. This has happened to me before with other low hp outboards. Hope this helps and best of luck. Thanks for watching!

I bought this motor as a project with no service history, and it was sitting for years. So therefore, a full service was necessary in my eyes. Maintenance and preventative maintenance goes a long way when it comes to outboards. Lower unit fluid is an every season replacement, and the motor did not run at all until I clean the carb, adjusted the float etc. Yes, the impeller was fine but I had already ordered it because I didn’t know the current impeller’s condition. The motor went from not running/barely starting, to first pull start every time. Thanks.

@JDAutoMarine Жыл бұрын
I would say that considering both the 5 and 6 horsepowers are 1 cylinder engines, the only difference is the carburetor being a little bit bigger, allowing it to have more fuel/air in the engine. You can probably get a bigger size carb for a 5hp, and just tune it right for that engine. Hope this helps.

Thanks for you time on this video. I've heard that one can change horse power simple by switching carburetor from a 4hp to 5 or 6hp any thoughts? Dose the propeller also need to be changed?
@JDAutoMarine Жыл бұрын
I wouldn’t say change horsepower necessarily, but by switching to a bigger mm carburetor it could potentially increase your horsepower, only slightly though. When it comes to propellers they don’t affect horsepower. You can certainly buy a higher or smaller pitch propeller depending on the needs of your boat. A smaller pitch prop will usually give you a better hole shot but slower top speed, higher pitch prop will give you slower acceleration but better top speed.

I know the feeling! I would say if it’s taking a while to start but is eventually starting, it could be weak spark - Bad magnetos at the flywheel / fouled spark plug. If not that then possibly a fuel issue, I’d check the vent on the gas tank, and the fuel lines running to the carb for leaks.

It could be a few things. You could either have the impeller in the wrong direction, a missing woodruff key, or perhaps the water tube isn’t fully hooked up to the top of the water pump housing. Another thing is that the water jackets could be clogged with salt,debris etc. If they engine isn’t pumping water consistently and shutting off that means it could be overheating. If the side of the motor on the water jackets are not cold then the engine is not being cooled properly. Let me know if this helps.
