Received. I do not have the ability to check both fuel pressure and spark output. I will go back to check the serial number Jason.
Marine Mechanic: Jason, Marine Mechanic replied 1 year ago

If you do are not able to check fuel pressure or spark what kinds of questions did you have for me?

Ask Your Own Boat Question
Customer reply replied 1 year ago
Well, I am not a mechanic. Are ordinary people usually knows and have the tools to measure gas pressure and spark output?
Customer reply replied 1 year ago
My question is easy. What are the possible causes?
Marine Mechanic: Jason, Marine Mechanic replied 1 year ago

There is nothing easy about it. There are way to many things to list, I could speculate for hours.

Ok then Jason, it means that my issue can not be resolved by E mails.
Sorry.
Customer reply replied 1 year ago
Without being a mechanic, I found out that my air filter made from sponge disappeared few days ago. i have changed it with a new one.
Is it possible that dirt came into my low pressure gaz filter?
Thanks Jason for you answer.

Hello, my name is***** will assist you.

Do you still need assistance on the motor?

Ask Your Own Boat Question
Customer reply replied 1 year ago
I did not receive assistance so far, just questions. Again since my air filter collapsed and possibly some small parts went into the carburetor and fuel filter should I try to first change the lower pressure gaz filter?

Hi Charles, sorry for the delay. Yes, the identification number is ***** Model Jan 2008 115XL4S sold in Canada.
Marine Mechanic: Charles, Marine Mechanic replied 1 year ago

Thanks, ***** ***** motor stalls, does it actually die, or just lose RPM? Is there a primer bulb in the fuel line going to the engine?

Ask Your Own Boat Question
Customer reply replied 1 year ago
Relevant questions Charles. The motor looses RPM and dies a few second afterwards. No, there are no primer bulb going to the RPM. I removed the gas cap earlier today, and the motor ran very well at idle for about 16 minutes, then stalled. Maybe a coincidence but at the same time high waves appeared. Maybe there is water in the thank. I will check later tonight when there is no waves/shaking so if there is water in the tank there will be no mix with gaz. Hope we will be kept in touch Charles.
Marine Mechanic: Charles, Marine Mechanic replied 1 year ago

If there is water in the tank, it would be on the bottom, the fuel would be on top of it. But the engine would have not run for so long. When you get to the boat, remove the fuel line from the front of the engine, then look inside it to see of it is coming apart.

Customer reply replied 1 year ago
The motor ran Very well on idle this morning for 20 minutes, then stalled. Fine I will change the fuel filter, and check the gaz line on Tuesday. Thanks Charles for you advice.
Marine Mechanic: Charles, Marine Mechanic replied 1 year ago

Did your alarm happen to sound when the engine stalled?

Ask Your Own Boat Question
Customer reply replied 1 year ago
No Charles, no alarm, just like if there were no gaz or air going to the motor.
Marine Mechanic: Charles, Marine Mechanic replied 1 year ago

Make sure that the fuel line going to the engine from the boat is not collapsing internally.
