OK, 3 prop shafts in 1 year, 2 in the last 3 months. I am running Bravo X drives with Sportmaster Lowers on an F29' CAT. 1.33 gear ratio turning 4 Blade Bravos, 34P props. High X dimension. Stock 496HO motors. Yes has the small prop shafts, but they are sheering off inside the carrier bearing where the shafts are the largest. I saw a mention in another thread of going to after market stonger prop shafts. Anyone had this problem and know the correct fix? Getting expensive leaving a Bravo on the bottom of the river this often, not to mention the shop costs.
