There should be a sticker under the engine hood that tells you the make/model plug and the gap.

The dealer showed me that... I didn't know about it either.

Here is some information to changing your 4-tec spark plugs;



4-tec plugs NGK brand, DCPR8E Gap/ 0.7-0.8 MM or .028-.031in.
To replace the plugs remove the Oil dipstick, remove the plastic cover over the engine, replace the dip stick. Unplug the wire from the spark plug coil ( it's part of the spark plug cap) wiggle and pull the cap/coil out of the spark hole. Be careful not to break it. Loosen the spark plug, insert the cap/coil in to grab the plug and remove it. Gap the new plug, remove the screw top on the top of the plug, insert it in the cap/coil push it in the plug hole. Use a socket to tighten it. Snug it up go about 1/4 turn, loosen and snug it up(this compress the seal ring on the bottom of the new spark plug). Put some grease on the coil cap where it meets the cylinder and insert on the plug. Connect the coil wire. Do one spark plug at a time. Replace the plastic cover. This should solve your problem.

You really need to add your Seadoo model and year to you avatar for future questions/problems. Use mine as an example.
