Suzuki Outboard Engine Shut Down While Underway

Marc of Wefings -- I should of listened to you from the beginning. Both the dealer and I thought is was the kill switch or possibly the neutral safety switch. Next time, if there is a next time, I will pay much closer attention to you, because you obviously have a lot of experienced with these sort of failures.

Thanks!

This fall of 2010 my 90hp Suzuki started normally, then ran rough. I shut it down, and it wouldn't restart on several tries. When it did start, I smelled strong odor of gas. Made it to my marina, where mechanic diagnosed "blown fuel line" inside cowl. Could that have been caused by a faulty harness install, engine vibration or what?
 
I suspect the fuel hose was faulty due poor materials, age, construction or if the gas contains alcohol and fuel line was not rated for alcohol, the fuel line broke out from the inside.
 
The Suzuki manual suggests replacing the fuel line every 2 years. I keep an eye on mine, specifically the portion in the direct sunlight.

I'm glad to hear there was no other damage or fire.

I see you are not too far from my neck of the woods.
 
Many thanks, Fellows! I'm sure that the fuel line should have been checked and replaced.

Does ethanol in today's fuel cause deterioration of fuel lines?

Lots of info on the 'net about this subject. According to one source:

"Periodically inspect/replace fuel lines.
Again, solvents are the culprits. They compromise the integrity of fuel lines, restricting flow, and they decompose fuel tank pickup tubes, leading to loss of fuel supply to the engine. New fuel lines resistant to deterioration are available from Mercury Marine, marked “USCG Type B1-15-SAE J1527 EPA Compliant.” The line is gray to resist damage from sunlight. A good rule of thumb: If a fuel line leaves residue on your hands, change the line."

The "solvents" in this case are those contained in the ethanol fuel.

--------------------------------------------------------------------------------

I heard that in this months BoatUS web Magazine but do not have acess to the article, they have an excellent article about fuel hoses made in Malaysia and other places that state they meet the appropriate standards when they don't. Can cause serious problems as they tend to start to deteriorate immediately, especially when exposed to ethanol. They were used by both manufacturers and aftermarket, as they thought they met all requirements. The bottom line is that you should check your hoses for the country of origin as well as the specifications printed. The only ones you can be sure of as made in the USA.
