I have a 2003 190 DC. I want to install a trolling motor. What size shaft do I need? What thrust is the best for this boat? Do I need the Triumph Motor mount, or are there other options?I have a 140hp 4 stroke Suzuki. My speedomitor does not start recording until I get to about 4,000RPM. I think I might be having a cavation problem with the pick up tube. Anyone else having this problem?
