That depends on the boat of course will need to know exactly what one it is because varies from brand to brand, but as a pure guess around a 70 hp max.

Re: Engine on 20' pontoon

My 20' sweetwater has a data plate on the console that states max weight capacity,max number of persons and max hp. Mine is listed at 75hp. I have an 85hp on it and it does fine.

Re: Engine on 20' pontoon

You should have a data plate, somewhere. The two Starcraft 20's we owned were both rated for 75.

We had one with a 75 Merc. 2-stroke and one with a 75 Merc. 4-stroke.

The 4-stroke weighed considerable more and you could see it when the boat was at rest. The 4-S fuel economy was twice that of the 2-S.
