Depends on what you are trying to do.
Keep the engine clean, Seafoam.
Stabilize fuel Sta-bil.
Either will not work for the other.

Im using the blue Stabil and Yamaha Ring Free In my 03 F90 for 6mo. now. no complaints w the 10% Ethanol BULL%#*& like before.I crank it every 3 weeks if I cant take the boat out in that time.it seems to run better w the blue Stabil.Ive used the Ring Free since I got the boat in 07, as did the previous owner.

Re: fuel additives - Yamaha

My Yamaha dealer recommends the following:

1) Ring Free Plus
2) Startron from Starbrite
3) Yamaha 2 cycle M oil

I bought my 2000 150HP OX66 from a very conscientious new owner. He did the Ring Free and M oil, and I'm not sure what he did re fuel conditioner/stabilizer. Check out the Startron, it seems to be the next best thing after Stabil and Seafoam.

Stabil Marine and Ringfree all the time, and with a fuel/water separater you should eliminate most fuel-related problems. My motor is a 1999 and never had a problem or had to clean the carbs, runs like brand new. If you think the additives are expensive, check the prices of carb re-builds and other fuel problems.
