hi every one
Does someone have the service manual for this boat? When I start the motor, they re a knocking sound for about 3 sec. Then it’s stopping, wondering if it’s in the jet section.

Is it in the water when u start it?

 

[Stephane Poirier]

No I started in the yard yesterday.

 

[bronze_10]

Well the pumps make all kinds of racket when not in the water! But I have not hear elanyone calling it a 3 second knocking sound. You sure its not coming from the engines?

 

[Stephane Poirier]

It could be I did not let it run ´cause I was’ t in the water. But it stop right away after a few sec. I could post a video?

 

[bronze_10]

Video would help...

 

[Stephane Poirier]

Looks like the video extension is’nt working, can I sent it true your email?

 

[bronze_10]

U have to post it on YouTube and then paste the link here..

Just to be clear
The knocking stops or the engine stops?

It hard to hear anything in the driveway

You could pull the impeller-shaft to eliminate the pump noise
Its should only take about 30 minutes and instructions are in faq at top of page

 

[bronze_10]

Yes.. I like @Scottintexas approach.. Its not hard. . Pull them then start it again and see. From the video it sounds like it is coming from the engine but its hard to tell.

You can pull the plugs and the cover in the connection to the pump and rotate the engine. It sounds bad.

Change the plugs and gap them.

Thanks for the answers guys,
1- could it be comming from the jet gates?
2- what plugs are we talking about?
i'm new in the boating

 

[Scottintexas]

i'm still confused, does the engine stop by itself or do you mean the knocking sound goes away (while the engine is still running) ?

by jet gates do you mean the "reverse bucket", that won't be causing any problem,
"plugs" probably mean spark plugs, these engines can be very finicky about spark plugs,

Where are you located at?
How long have you owned the boat?
When was the last time it ran correctly?
How old is the gas in the tank?

 

[Stephane Poirier]

Where are you located at? Québec Canada
How long have you owned the boat? 4 months
When was the last time it ran correctly? first time out
How old is the gas in the tank? 2 weeks

the motor does'nt stop the sound does'nt go away,
i will try it again in the water tomorow, if it's still bugging me i will pull the both shaft out and mak it run without it
when i bought it 4 months a go, at the dealer, everything was checked they've said!?!
look pretty much as your's i'd like to ear one run out of the water.
thanks

These boats sound like you are running a blender full of bolts when you start them out of the water. Check the oil level (should be at the low mark on the dipstick when cold) - do NOT fill to the high mark or you will over flow it, and get oil on your air filters. Once you've confirmed you have the right amount of oil and it doesn't look milky on the dip stick, I'd run it on the water. If she runs fine on the water....off you go! If not, come back here and we'll continue to assist.

 

[Scottintexas]

Iagree with Julian, to me, it doesn't sound much different than mine out of the water,

be sure to look at the FAQ tab at the top of the page for lots of great tips and DIY ideas and in my signature below the link for a list of known issues with this type of boat,

Especially take the time to watch " how the cooling water flows in my Yamaha" and make sure you understand how the cleanout plugs work and consider some type of lock for them.

 

[Stephane Poirier]

Thanks for tips
i will try it tomorow

 

[Stephane Poirier]

Well finally it run’s fine on the water, yesterday was awsome riding it on the lake. Easy to start, sound’s smooth, water flow’s out on each side, the only thing is I have a hard time to keep both motors at the same RPM, always 0-500 RPM different. Does it really matters? Or it need a adjustment? Thank you for the earlier help!
