[QUOTE="fishing66, post: 420102, member: 21255"] Howdy, Thanks for your note and yes, some more info is available. I added a set of TH Marine 5-degree transom wedges and took the boat out on a lake yesterday to test. The bow rise is gone and the boat handles well. The engine height is not quite dialed in yet and it will probably take another trip or two to get it exactly right.....too high and it cavitates, too low and it plows. I installed the Rockproof UHMW intake foot and that did indeed lower top speed by about 2 mph over the stock foot. That's not a deal-breaker as impact protection was the goal of this entire project. There are some minor issues to work out such as placement of the transducers etc. The real test will come when (not if) I have a serious rock impact. Not looking forward to it, but hey, that's jet boating! :oops: [/QUOTE]
