I'm with ya Moose! I went with the 6" manual plate because my engine was spraying water all over the place because the cavitation plate was too low, it's was on the middle hole. I now have the cavitation plate at 1 3/4" above the keel and it's perfect. Really easy to dial in the engine height with this set up. Here's what I bought....

When you see this product you wonder how they make them for this price. Danny would have to go the next size up which is up to 400 hp. He's in the big boy league!!
