Trolling Motor Question

[togzilla]

For anyone who has a trolling motor on their boat.
I have already decided on a new Minn Kota Instinct trolling motor for my Sea Hunt Gamefish 25. Trying to decide between a 87” inch and 100” shaft length. The distance between my bow and waterline is 43” so the 87” should suffice. Just wondering if anyone else with a similar size boat has an 87” shaft and is it able to stay in the water in 3-4 ft seas? Not concerned with the price difference between the 87 & 100 but more about losing some forward seating area due to the longer shaft. Any experiences with boat owners who have an 87” shaft would be appreciated.
