I just bought an 80 lb. Terrova I Pilot and used it for 10 days in the Boulder Junction area, my favorite place in the world. The features that the I Pilot offers are awesome but I experienced a few problems. About 6 times when I selected the anchor feature or the auto pilot the motor would spin about1 1/2 to 2 times and then stop. After spending $1400.00 this scared me quite a bit. I upgraded from a 55lb auto pilot that I had for about 8 years until it broke (my own fault, I didn't have the transducer wire properly fastened and it wrapped around the prop). In the last year of its life whenever I activated the auto pilot feature the motor would just spin in circles making it useless. The other problem I noticed was the battery life. I am a camper and one of the main reasons for getting the 80lb. thrust was to maximize my time on the water without having to recharge the motor batteries. My old 12 volt motor(rigged to two 12 volt batteries) lasted close to 7 days, using it sparingly. The 80 lb. I Pilot only lasted 2 to 3 days using it the same way (only using 1-4 on the power dial). I have 2 Trojan deep cycle batteries that are about 4 years old and cost around $175 a piece. I charge them with an on board charger every time I am done fishing for the day with the exception of when I am camping, two to three weeks a year. I also leave the charger on all winter. Granted the batteries are not new but last summer when I was camping they seemed to work great. So now I have a brand new trolling motor that seems to malfunction and draw a lot of power with the gps constantly running. I called the marine store where I bought it and they said to talk to the local factory authorized repair guy instead of helping me personally with my problem. Does anyone know how much the I pilot draws from the batteries, because even if the motor is not running the gps is always on. Secondly the spinning of motor worries me. And thirdly any info on alternative charging methods; outboard charging all batteries instead of just starting battery or charging boat batteries from truck while trailering. Any advice would be greatly appreciated. Thanks.
