"I recently purchaced a 1994 hydrodyne grand sport with a PCM 5.8L EFI. The boat sat covered and unused for 3+ years and there is a good amount of rust on the throttle body butterflies and a little in the manifold (looking through the throttle body). The boat starts and runs well on the hose. My question, run some carb/EFI cleaner through it or pull the throttle body and rebuild it?"
