Anybody know what the main difference is between regular seafoam and marine pro?
Is it worth paying the extra $$$ for it?

Sea Foam Motor Treatment is a general-purpose fuel and oil system cleaner, while Sea Foam Marine PRO is a specialized, marine-engine-specific version that adds features like enhanced corrosion protection, better fuel stabilization for marine storage, and is formulated without alcohol to meet the stringent requirements of marine engine manufacturers. Both are 100% petroleum-based products that clean and lubricate fuel systems, but Marine PRO is the superior choice for marine applications due to its tailored formulation.

The label is the only difference. Well and price. There might be a slight change in the formula but I wouldn't pay for it. Use good fuel and it's not necessary.

Seafoam was invented to keep outboard fuel fresh in the 30s. It’s in the name. Fuel is much different today to where the product doesn’t do what it should, and it may never have.. but regardless you don’t need the marine version as the original was the marine version. It’s pale oil, alcohol and naptha

I've always liked Mercury Power Tune over Sea Foam . . . it seems a lot stronger in terms of carburetor cleaning and combustion chamber cleaning

Seafoam is a SLOW acting solvent. It does not suddenly dissolve all the crud at once and block tiny fuel passages.
I use it 1 time about each year to regain the lost mileage do to crummier modern gasoline.

Since you didn't ask if Seafoam itself is worth the money, I'll leave that alone. If it is a product that works for you then by all means pay the extra money for the extra benefits.

However, this question is like asking people if it's worth paying for the sprinkles on an ice cream cone. Some will tell you not to eat ice cream because it's not good for you. The rest will debate whether sprinkles are worth it or not, based upon personal preferences. If you like sprinkles in your Seafoam, go for it.

This is prob the best description of the great seafoam debate. Personally I wou.d not pay for the sprinkles but I would def eat the ice cream because sometimes, imo, about 70% of the time it fixes my problem and worst case I just spent 8 bucks on ice cream and I feel good either way.

It works okay as a decarbonizer, which isn’t what it was designed for. Water itself can work okay as a decarbonizer though

Used it as a fuel additive (carbon inhibitor) in the boat until I switched to an oil with carbon guard in the formulation.

Add 1 oz. per gallon as a carbon inhibitor and fuel stabilizer to the 2 stroke mix for the lawn equipment

there is no mechanic in a can
Sure there is.....how many mechanics will just clean out your motor with SeaFoam, then charge you 150 bucks for " service" ?? The mechanic used the same can as you or I, but charged you for adding it to the gas. My old retired mechanic friend admits to doing that on a few ocassions in his working days. Back in the 70-80's, many marine mechanics used a can of snake oil to solve an issue with an outboard motor. A can of liquid can't make physical repairs but when it comes to cleaning....it works when used as intended.
