AC are the OEM spark plugs and they are excellent plugs. I would recommend you buy AC/Delco Iridium Spark Plugs. They are as good or better than any others you can buy. NGK are also great plugs and I have been told they make the AC plug but I cannot verify that.
Remove the spark plugs, dump in some 2 cycle oil over each piston, replace the spark plugs, turn the engine over 1 or 2 times, Let the Jet Ski stand for a while.
I don't know when Cadillac started doing this, but they eliminated the coil packs and have since been using coil on spark plug coils. They are directly over the plugs on the engine. You have to remove 4 or 5 bolts to access them.
For replacement plugs, it is recommended to use stock Toyota Denso spark plugs. They are dual electrode and pre-gapped at 0.044". If the engine has been modified, the type and gap on the plugs may vary depending the modification and desired performance.
Bosch spark plugs has been a reliable brand. And many auto parts stores and auto mechanics would recommend them. Some Bosch spark plugs come with a warranty.

Well, honey, a 2004 GMC Envoy typically has six spark plugs because it's a six-cylinder engine. So, unless someone's been playing around under the hood, you should be good to go with six spark plugs. Just make sure they're all in there snug as a bug!
Spark plugs can dry out relatively quickly, often within a few minutes to an hour, depending on environmental conditions such as temperature and humidity. If a spark plug is wet due to fuel or oil, it might take longer to dry, especially if the engine has not been running. In some cases, it may require several hours or even a day for a spark plug to fully dry out in damp conditions. Regular maintenance and proper engine operation can help prevent spark plugs from becoming excessively wet.
Spark plugs not producing enough spark. Battery doesn't have enough charge. Old fuel.
Engine is likely Hydro-Locked from ingesting water while running. Remove the spark plugs and try to crank the engine.
I'm not a mechanic but it sounds like there has been a mixup involving your spark plug wires , either at the coil pack or at the spark plugs
