I have a 2014 Puma FTD. I have 2 8′ Power poles. Lithium batteries for my electronics and trolling motor, but have an AGM for cranking. The boat has a 250 Optimax on it. Currently I’m running a Fury 26, but the whole shot seems to be lacking when boat is loaded heavy. I’m thinking of going to a 4 blade to help on this, and I am not concerned about losing some on the top end. I very rarely go over 70 anyways and the fury 26 will push my boat just over 80. Has anybody have any experience with the Razor xl 4 blade?
