Stainless prop will also alter revs for same pitch

Great video … I am quite new to the game and still learning.. I have an old 1978 zodiac sib in mint condition and have a 15hp 2 stroke mariner .. I have seen the recommended WOT .. but how will I know on the water what the revs are ?
Keep it up .. vids are great
Thanks
Glen

@yicafresh it is difficult without a tachometer you just have to go off engine sound and use your judgement
