What does it means when a spark plugs gets wet with gasoline

It could mean the plug is not firing, or the injector may be at fault, like having a stuck open injector or leaking. First make sure the plug is sparking.

What could I damage on my boat fuel line? Primer bulb, any filter ... ?

There could be several reasons. I'd first look at stuck floats in the carbs. I believe there's 3 carbs and if all spark plugs are wet all floats are sticking.

But assuming it didn't overheat, and the spark plugs are wet with fuel (as opposed to water) - sometimes a defective coil will short out only when it gets warm (most time they short all the time). They can be tested.

A very good mechanic once told me there are only four things to concentrate on: Suck, Squish, Bang, and Blow. In other words, Fuel delivery, Compression, ignition system/spark, and proper exhaust. My experience has been that I've never had to worry about Blow (knock on wood) with an outboard. Others have however.

Additional advice: The number 1 cause of outboard problems is gas. Todays fuels are great for fuel injected cars but break down sooner than old gas mixtures. Always put a fuel stabilizer in you tank. It's cheap and only takes a few ounces to protect from hundreds of dollars worth of carb work - and avoid sticky floats.

1997 Gastron boat cranks but wont start

Start with taking the spark plug out. If it is a light brown/tannish color and dry, then you most likely have a fuel supply problem. Check fuel supply lines, fuel pump if you have one, plugged jets/orifices in the carburator. If the sparkplug is wet and smells like gasoline, then you have a spark issue which could be coil problems, bad spark plug wires, bad spark plug, batter that is almost dead.

Good luck

I have 2007 1098s that turns over but wont start.i have fitted a new battery and sparkplugs but that has had no effect.have also checked all the fuses.

After you have turned it over for a bit, take the spark plugs out and look them over. If they are wet and smell like gasoline, then you have a spark issue (coil, spark plug wires, etc). If the spark plug is dry and has a tannish brown color to it(although if you just replaced the plugs it will just look new and dry), then you have a gasoline issue in which you need to make sure fuel pump is working or plugged fuel filter if it has one or some other disruption in the fuel supply line. If you take them out, figure out which way they look and report back if you like and we can go from there.....

Good luck

Wet spark plug

Spark plug gets wet because it's running too cold. Loosen plug and retighten only tight enough so it doesn't loosen from vibrations. Just a tad beyond hand tight is enough. This way the spark plugs heat is not dissipated to the cylinder head and run much hotter burning away any excess fuel deposits.

Larry - the manual isn't really going to help you get this started. Press the primer bulb - if provided a couple of times to get gasoline into the cylinder. You may hear it squirt - or even see it drip from the carburetor. Try starting. If it didn't, remove the spark plug. Is it wet with gasoline? Is the chamber filled with gasoline fumes (you can slowly pull the starter rope to move the piston up and force the air in the cylinder out to smell for gasoline). It wet, dry it throughly. If there is no gasoline odor, give a brief spray of starting fluid or ether into the spark plug opening - and install a new plug - or the clean old one. Attempt to start again. If it tries to start and sputters, you likely have a fuel delivery issue. Make sure the shut off valve at the bottom of the tank or inline on the fuel line is open. If it is, I suspect that the float in the carburetor or needle valve needs to be cleaned / adjusted or replaced. You may want to have this done for you as there are some very small parts involved and attention to detail when re-assembling will be required. Carburetor rebuild kits are available for most of these engines.

My van will barely start only if I push the gas pedal to the floor. And still then will die almost right away. I can smell tons of gas, Plugs are wet with gas too. I did change the o2s and have the same...

I don't think it is your O2 sensor especially from the catylatic, because you mention smelling like gas and presence of gasoline. "Plugs" hopefully referal to the spark plugs, try to trace where you see gasoline and where it is coming strongest from. This is a case of leaked fuel line, fuel rails, fuel injectors.
1) Trace the source of where it is wet, there maybe a leak somewhere and you car is not getting the amount of fuel pressure to combust and thus make the engine dies. 2) Check your fuel injectors, fuel line rail, could be leaking or become loosen and is spraying gas when the fuel line is pressured into the spark plug socket. 3) You may have a dead spark plug one or more, and isn't combusting the gasoline, thus creating no compression leading to engine dying. 4) Leaking head gasket. Best is tracing where the gas is spewing from. That should help.
