which would you choose. I have the 35hp with no mods now. I would like to upgrade to either of these to get a little more speed under load hauling. My current motor does great when its me and the dog. When It's me the dog a buddy decoys and guns other equipment I get impatient. so which would you choose. I like the cdi technology, but would the 45 mag be more powerful? how much more than a 35 does the 45 weigh? thanks for your input.
