[QUOTE="onthewater102, post: 417532, member: 13702"] There has to be a way of calculating how high to raise the mounting point based on the anticipated top speed of the boat and the amount of offset based on how quickly displaced water will rise to fill the void behind the boat and then based on the speed of the boat @ top speed. I should from this be able to determine how much the water will come up after clearing the transom in order to set the height of the new mount accordingly...but I can't find the information I need. I tried guestimating by taking measurements off of several different manufacturer's setups but there doesn't appear to be a direct relationship between offset distance from the transom and the distance above the bottom line of the boat that the cavitation plate ends up set to. I thought perhaps this would have been due to the top speed of the boat but the aftermarket manufacturers of these tilt-trim setups have no way of knowing what that would be for all applications.
