I was wondering what size shaft length I need for a 2001 Tournament V-18? I just bought the boat in the fall and I'm getting her ready for spring. It has a 45 inch shaft bow mount Minn kota that I'm looking to upgrade and I'm wondering if 45 is good or if need a longer shaft. I'll be fishing on some rougher bouncy days but if I can get away with staying at 45 inches I'd like to. Hoping someone who's had the boat can chime in as I'm not really sure how close to the waterline the bow normally sits in the water. Thanks
