Suzuki 2.5HP outboard dying

[andrewedmondson]

My 3 year old 2.5hp Suzuki was dying after running under load. I also noticed that the oil level was too high, black oil.
I performed a service and found a brush hair in the float chamber.
This didn't fix the problem.

After leaving it for a while it often is difficult to start. Once idling, it dies on throttling. Eventually it gets running with no load.
On load, it sounds too noisy. If I keep the throttle constant it keeps going. As soon as I throttle down, it dies. Then I can restart it and carry on.

I'm wondering if this is a serious fault, e.g. petrol entering the sump and thinning the oil (hence the oil level too high).
Rather than take it to a dealer, I could replace the carb but this is a gamble.

Sailing on a shoestring.

Just going through this myself. Have replaced jets with new ones (rather than trying to clear the tiny holes in the old ones) and just waiting on a new fuel cock as the inbuilt filter had collapsed.

Same here new slightly larger jets and a darn good clean of the carbie... pretty good now.. do a google search and there is plenty of info on what jets etc to replace ..

Jets. THe curse of all small outboard.

Fuel evaporates and leaves residue. The jets are minute and clog

I would love to be able to say a Williams is more reliable !

Thanks for the replies. Such a good forum this. I guess it's the number of subscribers.
I'll hold off taking it to a repair shop and order some new jets.
btw I have always use an ultrasound machine to clean the carb. What do you think about this?
