Best Sea Foam product for 4 cycle snowmobile engine [SOLVED]

I have used original Sea Foam for years in my vehicles and outboard motors. Marine PRO is new. I will start using it in all my outboard motors.

Question#1: What is the difference between the original Sea Foam and Marine PRO?
Question#2: What would be the preferred product for 4 cycle snowmobile engines that also are used in a wet environment? If it makes a difference, my snowmobile is a 2012 Ski Doo with the 600 ACE four cycle engine.

Hi John,

Sea Foam and Marine PRO are both made from 100% petroleum ingredients that can’t harm your engine. The difference is Marine PRO is specially formulated to meet all the core things boat engine owners want in a marine fuel system treatment – it cleans fuel passageways, lubricates, stabilizes fuel, and provides corrosion protection to upper engine areas. Marine PRO doesn’t contain any alcohol, which is something marine engine manufacturers can be particular about.

For your snowmobile, Sea Foam Motor Treatment would be the best option.

Hope this helps!
