    Tracker gas tank vent?

    Have a new Tracker Pro team 175 with 60 Merc 4-stroke. When are you supposed to open/close the boat gas tank vent?

    If it has a built in tank there is a vent already built in. There should be nothing to do but gas it and go.

    Built in tank, but there is a valve on top of cap that can be opened or closed.

    Tracker went to the valve style vent at the top of the cap? My cap on my 2008 is a vented cap. I would buy a vented cap for it so i wouldnt have to mess with it.

    Just curious when you should open or close the vent? Should it normally be closed when not running motor, then open the vent just before I remove the cap to fill tank or open vent when I get ready to run motor then close it when finished?

    Yea thats right. Closed when not in use but open before removing the cap or open before you want to run the engine. I like mine being always vented in the summer it gets hot in the battery compartment and fuel swells too much.

    During heat vapor fumes will also develope and create pressure. I would leave it open most of the time, especially in summer.

    I have tracker PT185, the vent is thru the top of aluminum behind the engine. Everytime I am sitting in the water or come to sudden stop. Water splashes up and into the vent. Thus ending up with water in fuel issues. If I disconnect the vent hose and plug it or figure a way of having it as air exit only. Or purchase a vented cap, will that work?

    Other suggestions?

    If water gets in then that is a very undesirable setup. If you have the same style fill neck and cap as the later model trackers like mine then replacing the cap with a vented cap may be a better option. Have never had any issues with the cap on mine. I would think an exposed vent hose would allow alot of bad things to get into the tank. Dust and water being the worst. You have a pic you could post of what you have now?

    The 98 has a flat fill cap, maybe an 1/8th inch lip then it's the screw on cap which is more like a cheap cap. The vent sits 6 1/2" to the left. It to has a low lip.

    Same with my PT185... I can get water in the tank if I stop to fast when on plane (when water comes up over transom) I have to be careful and watch it...

    Enough water can get in to make it run like sh*t, but not enough to ruin your day/trip... just pull the primer bulb off the motor, screwdriver to push the pin in, and prime the bulb and fill up a glass jar about 4oz is enough to get the water out...
