Hello all , fishing for zander here in Finland. Last year when trolling boat would not go slow enogh to catch bigger fish. Recommended is 3.5 km max for the smaller fish and that is the slowest i could go trolling. propeller is 10-1/2x13, what is a reduction in speed dont need much but very confused, i know if i change diameter it will fall but what about pitch, my local shop is sellling this now, will this help. https://www.motonet.fi/fi/tuote/386078/Hustler-potkuri-H1-1012-10-34-x-12 or is anything on this page better https://www.motonet.fi/fi/kategoria/351/437750/Potkurit-ja-keskiot
