Look under the left exhaust manifold. If you see a black snap on plastic cover, you have the 03 or newer model .The high pressure pump is behind the black cover. The low pressure pump is next to the water separator front of the right exhaust manifold.

According to the S/N, you have the late model GenIII fuel module(assuming it is a Bravo drive). It is located on the starboard side of the engine, lower front. The vacuum hose goes into the regulator mounted on the top. There have been a few problems with paint under the regulator getting sucked up and stopping up the screen. It is very easy to remove the regulator. Just 2 screws and pry it up. Make sure there's no loose paint. If it's a twin engine boat just swap regulators.

Okay great, thanks I will try all of this on Saturday. This is my first time messing with the fuel system. Any tips on doing this safely without getting gas everywhere?

It's a returnless sytem, so you have to relieve the pressure in the rails. Do it in a well ventilated [ outdoors preferred ] area, rap some rags around the Schrader valve while pressing on thevalve with a small screwdriver. Do same when swapping the regulators over, with rags underneath catching some spill.
If your symptom switched to the other engine , you'll know to replace the regulator.

You guys rock. Thanks so much for the help. I pulled off both filters then swapped the regulators. For the first time since buying the boat both engines are sounding identical when they run. No more smoke.
