I have recently bought a 2012 175 Bow Rider which seem to have a strong petrol smell but there is no indication of a fuel leak, does anyone have any thoughts ?.

Check you fuel lines and around the fuel filter when the engine is running. It is possible the lines leak only when under pressure. Make sure you properly vent prior to start up.

This fuel smell coming from the vent ?

You overfilling the tank, air gets warm and the fuel expands pushing fumes out the vent and if overfilled fuel will come out the vent.

And yes i agree, check all fuel hose clamps etc.

Absolutely do not run the engine if you suspect a leak. This can lead to a fire or explosion.

As Chief Allen mentioned, check the vent, as well as all the hoses and clamps. Pay particular attention to the filler hose.

As indicated he already checked for obvious leaks and found none ! This leads to my post. I just fixed a boat that had the smell of fuel and no leak could be found. However by lifting the hatch turning on the blower, starting the engine after a few minutes I was able to find the leak which was at a fitting and it only leaked when under pressure.

I recently smelled fuel. Looked by the motors and in the bilge and saw nothing. Left for a week and came back to a STRONG fuel smell. Looked again and found my starboard tank had a small pin hole leak. I caught it just in time. Always question older aluminum tanks. Just say'n
