Got out for a few hours for a shakedown on boat. Everything seems to be ok. Wet a few lures without much success. Main lake was 50 degrees and coves 52. Made a couple of runs down lake at wot and was surprised at speed attained! Actually broke 70mph. Never even came close to that in the past. Put two coats of Pro-tec sealant on hull during week previous. The only explanation I can think of.
