I've been fishing the 101 # Ripetide Minn Kota for years and love it. Thankfully I purchased the 3 year extended warranty, as it's be reshafted a couple times, don't buy it without one as it's not as indestructable as they claim

. Otherwise I love it, but you'd have to actually take some measurements on your bow height off the water to make sure you have the shaft length to make that work. Remember any kind of chop or rollers and every time the bow comes up so does your motor. I have a 52" shaft on my Lund and it's perfect for my boat.
I'd also recommend a good on board charger, one designed for 3 batteries and is completely waterproof and sealed. Saltwater demands a minimum of 24V, but since going 36V years ago, I'd never go back.
