125 HP on my 1975 20' SF..Under powered ?

[Texascoastalfish]

Hey Yall,
I'm new to this board and purchased a 1975 20' CC. It has a 76' 200 HP Johnson. It has seen quite a bit of Salt water and Im just not sure of its lasting power. It runs and shifts OK. Havent been on water. I want to power down a bit to a 150, or maybe 140 looper. Family member has a 125 Force that has been well maintained. I know the pitfalls of Force outboards, being as they are no longer made,I can get this motor dirt cheap and run it on my CC until I get a newer 150. QUESTION. Does anyone know if its enough to push my craft at 30+ knots ? Anyone know the Min HP rating ? The Max is 175 I believe and this 200 is a big 'ol V6. I am very excited about the clean up and rebirth of my new baby. I live dowm in Galveston Texas and hopefully the pride of West Bay someday. Thanks in Advance !
