Not sure how deep your lake is or any features or vegetation. When I fish from my kayak, I use a portable fish finder. Gives me a depth, structure, fish and weeds read out. Have done much better locating them with that. I drift fish 98% of the time. Bottom bounce weights and 3' leader with snap swivel on main line. Have done extremely well with that set up. You can get over a school without spooking them with a motor. You may even try jigging which I stink at. Good Luck!!!!!
