Thank you John , thank you LazyPelican ,
I have 29 hp engine , after service – all was ok. My question is , how many knots I gain when I change propeller – when I changed prop in my last boat in Poland / 8 m long , 3 tonn , 16 hp engine , for 3 – blade , I found 3 kn , but I lost 2 kn when Im sailing .It is reason that Im thinking about folding prop.
Im sorry to disturbe you , but in Croatia we – unfortunatly – so ofen use engine.
