Follow this to your air filter. Face the rear of the boat. The plastic cover atop your motor with the label 3.0 v6 hides the throttle body. It's actually a sealed airbox, not a cover. This is where air is sucked in to the motor. Look on the bottom left (facing the rear of boat) of that plastic air box and you will see about a 3/4 rubber tube plugged in to the plastic air box. The air filter is located where that plugs in to the plastic body. Give it a 1/4 turn and it comes free from the plastic body. Just check for good air flow. Give it a clean with a compressor. If blocked then you'll need to find a different one. I've been able to clean mine w/o issue.
The fuel filter, if original, is a gold can about 1.5inches in diameter and is at the front of your lift pump, which is black and sits atop of your VST. It's where the fuel lines come from the boat's tank. I've always been able to back flow fuel through it and keep it clean. Not had to find a replacement. I'm sure you can find one.
