Fishing from a boat, instead of the bank, is still new to me. Please bear with my novice type questions. I have a 1988 Bass Cat Pantera 2. I have had the engine, Evenrude XP 150, looked over, including the compression. All seems well. However, I have not been able to plane-out and aquire hardly any speed. I have went to a four battery system and both live wells were full if that added weight had any performance effect. Any thoughts would be greatly appreaciated. Thanks!
