I currently have a Motorguide Great White with a 45" shaft on my 1993 19'3" Intimidator. I am getting ready to upgrade to an Ultrex. The Motorguide fits perfectly and does not obstruct opening my rod locker on the left side of the boat (I have it mounted at an angle on the bow, not straight down the centerline of the boat). I am debating going with a 52" Ultrex, but I don't want it to block access to my rod locker etc. As expensive as they are, I don't want to order something that I'm not happy with. I really don't fish tournaments anymore so I may not necessarily be fishing water with waves large enough to make a 45" shaft come out of the water....but you never know. Does anyone have any input on the 45" vs the 52" UltreUx mounted on a 19'3" Intmidator?
