Hey, I had a problem where my motor same as the video, was back firing do you think it could be my fuel filter?
In your video, you showed an impeller but didn't show how to replace it? Any follow up video on replacing that part? love the video very helpful. I have a 6HP
Brilliant video and explanation. I might try my own basic service based on this advice.
I found this video sooo helpful I have a 6hp Yamaha outboard and I haven't used it in a while and I went to start it and she wouldn't go so I really enjoyed this video and love your easy to follow descriptions and instructions
been looking for a video or some forum that can help me with the control switch on my Yamaha 6HP outboard
How I do gap the spark plug im confused what do I look up on KZread to make it between .6 and .7
i have a problem with my motor at full throtle it seems to be running lean and it goes like it should on 1/3 choke and it seems that i have to change to a bigger jet but shouldnt the original jet work for the motor or am i missing something
Thank you
Good video
Great video. Clear and easy to follow :)
Hello ! Was out on the water for an hr no issues with this engine. I stopped it for 25 mins and went to start again and it wouldn't. It's my first outboard and didn't know you have to put the throttle on a certain a position and then pull the rope, I have been pulling the rope without throttle on set position and It has always taken me 7 pulls or more to start it so I think I flooded the motor. How do I de flood? is there such a thing? I tried putting throttle all the way open and choke closed to possibly deflood and cranked it ten to fifteen times and then tried with throttle on the start position to crank but have had no luck starting, tried also with choke on for a few strokes with no luck either. Could I have fouled up the spark plug?
do you have any idea if there is a port for a hose to flush the system? It is not mentioned in the owner's manual and I cant find it mentioned online. Thanks.
great video really helpful, i have just bought a 2005 yamaha 4hp 4 stroke outboard seems in really good condition and starts well i just have a issue with it not idling, unless i rev it kinda shudders and then cuts out, any ideas for a person that is fairly decent at diy but new to outboards, if its not too intricate i could probably do it myself like i will this service thanx in advance

First step is to take the carb off and clean it out fully.

Great video. I couldn't help noticing that the in gear protection stopper is missing from your engine. It's a white plastic lever at the at the top of the engine that the cable goes to. Mine is missing too. Have you any idea how to replace these? The part number is 67D-15794-00 and is called a 'stopper'. Thank you.

Hi, what size are the gaskets?
I have a Yamaha just like the one in the video. Works fine but will not start unless carburator is emptied from fuel first. Any suggestions?

@@FixitSam Yes! Do you know what it does? I found out that mine was almost broken at the joint on the black box and the pipe. I glued it and connect it and now the outboard works fine. Before that, I had iddle problems and sometimes the engine stopped and had to pull many times to start against using the chock. So, if you know was it does you could help me a lot to undersand!

Hi Sam, I've just become the owner of an identical outboard to this (came with boat) and followed your helpful tutorial to replace the gear and engine oil and plug. My issue is that it won't start or even spark (I've never actually seen it running). Any pointers to what I should look at next (given I've replaced the plug) ? Many thanks

No spark at all? Are you grounding the plug as you test? If no spark at all check the kill switch first then the coil/magneto.

@@FixitSam Hi Sam, thanks for the reply. I'm learning as I go here. I don't know what you mean by grounding the plug. I've looked at the kill switch, lubricated it, added a spacer to ensure it was extended enough to no avail. I do notice though that with a full tank, the fuel filter is bone dry. Could that be the issue? (Blocked fuel line?) Thanks again - David (Mayo)

No offense, but changing the engine oil and not changing the filter? You may as well have not bothered. And, sorry, but most people will be doing this at the end of the season, ie just before putting the engine away for the season. So you change the fuel filter but dont drain the fuel out of the tank? Youze dude. Not the way we roll!
