Sorry i have not gotten back to you sooner. I apologize for that. There is no particular rule concerning your engine. Our rules do state that each boat must have a working livewell. i would think that your portable livewell would meet that requirement. Our next tournament is on Pirkey this weekend. Our meeting is at Trinity United Methodist Church, 3470 Gilmer Rd. at 6:15 this Thursday night. You would need to attend & be voted into the club, pay your dues($25 per angler),& your entry fee ($35 per angler) to fish with us this weekend. I know this is short notice, but i hope you can make it &come fish with us. Thank you for your interest in Sportsman Bass Club of Longview.
