I've run a Yammy115 for several years in fishing the shallow marsh areas of South Louisiana and have been pleased with how it handles grinding in the mud without a lot of problems with stopping up the water pump. Has anyone used a Suzuki DF140 in those conditions? It seems that some engines are a sissy when it comes to shallow water and I'm thinking of buying a 19' Fishmaster with a DF140 on it. Are they tough enough?
