Sea Foam Marine PRO for a 5.7 V8 Volvo Penta engine [SOLVED]

Just bought a 2005 Crownline 226 LS with a 5.7 V8 Volvo Penta engine. Is the Sea Foam Marine PRO good for this engine, and if so, do I put it in with full or empty tank?

Great question, Eric. Marine PRO will work great in your Volvo boat engine! When added to fuel it’s always working to clean, lubricate, and protect the fuel system.  How I do it: I always try to add any Sea Foam treatment when the tank is low to max the cleaning concentration. Have fun with your new boat!
