Planning on trolling the upcoming season. I have always been a drifter from way back in the 80s. My question pertains to using a drifter sock/bag to slow me down. Unfortunately last year when purchasing my new rig I wasn't able to afford a kicker. Plan to in near future however for now I must make the 150 yamaha 4 stroke work for me. I would appreciate any ideas on whether just one on either port or starboard side or would I be wise to run two of them, one on each side? I have seen the plates that can be attached to the lower unit but I'd rather not. Give me some thoughts on this matter. Oh yeah, by the way with my 196 fishmaster and the Yamaha I tend to be around the 2.5 or so speed at idle. Thanks all and good luck to you as as always.
