just traded motors with a friend. i now have a 1999 tohatsu 50 2 stroke on a 98 grumman 1648 sticksteer. the prop is toast and there are no markings on it, and he had it on a 17' skiff (heavy) so he was underpowered. i have to have a prop, but without a baseline to go on i'm not sure what to get. if anyone has a similar setup let me know what diameter and pitch your running please.
