How long will you let your boat sit before draining the gas from your motor?
Ok, like I said....noob here...what is...and how do you...fog a motor?I would not drain the gas at all. Unless you are storing it for a long period (more than 6 months) I would just put in an additive to the fuel (pickle the heck out of it) and then fog the motor. This is only if you are not going to run it for more than 3 months. The fogging basically puts a layer of protectant on the inside of your motor to protect from corrosion, rust, and other damaging elements when not running it. The best thing to do for a boat is to run it every once in a while. This keeps everything free and lose, and oils your inside parts to protect them. Hooking them up to the flush and running it at idle is better than nothing at all if your not going to fog it. The next time you go to run it, put some fresh gas in it and make sure it warms up properly before each use.
some guys spray fogging oil into the carbs as the engine runs out of gas, Others will pull the spark plugs and spray the cylinders while turning the flywheel some by hand. Either way you are putting a layer of oil in the cylinders to prevent flash rusting and sticking of the rings. Has nothing to do with keeping the carbs or fuel clean and is really for times when the motor will be stored for long periods or stored on the water as all that moisture and fog can condense in the engine. If you are one of those guys that parks the boat in Nov and doesn't bring it out again until April you need to drain your fuel and fog your cylinders.
several brands around this is just an example. http://www.zoro.com/i/G2696933/?utm...w6PuBgKseAhzCX4xKKB5JRCE9LnKpF3yQ8aAjyw8P8HAQ
I drain the carbs every time its the best way to keep the carb in good shape. You have 2 ways to do it the easy way and the hard way, easy way unhook the fuel line from the engine run it until it dies. Hard way take the cowling off and crack the drain plug on each carb.
thay makes absolutely no since running the engine will drain the bowls adequately look up "venturi effect" then get back with meOn a carburetor engine unplugging the fuel line and running it until it quits leaves fuel in the bowls.
Most engines with bowl drains......you are talking about a coupla minutes time to do it.
If I used the boat once every week or so, I'd drain the bowls.
This gas today aint nothing even close to the gas we had 15-20 years ago. This stuff is crap.
Carb bowls have a low spot, designed to allow a small amount of sediment to collect to protect the "pick up" from clogging. Running a carb "dry" does not truly remove all of the gas just most of it. a small amount will remain in that low spot. Running them dry helps lessen the chance of issues, draining prevents it. The small amount left in the low spot will turn to goo, dry up. varnish and then when the carb is loaded again with gas it can break loose and clog stuff. Running dry is better than leaving full, draining is better than running dry. Some carbs have the drains hard to get too behind breathers etc. Drop a drain screw into the "dark abyss" and you have to tear stuff apart to get to it or try to chase down a replacement so pack a paper towel under the screw to catch it if it escapes. That also catches the gas that runs out.thay makes absolutely no since running the engine will drain the bowls adequately look up "venturi effect" then get back with me
