No that is not the issue. The issue is that the 2.5 EFI has a very low torque range for newer hulls. This was the reason for the 3 Ltr. EFI 200 and we were involved in that project. There were some brands of boats that had a much worse situation than yours, which is why in 2004 Mercury had over 100 leftover 20″ – 200 EFI 2.5 engines at one point. The engine works well on a Pantera Classic, and it was great for salt water boats that have a totally different hull than bass boats. Though on most bass rigs it was softer. In January 2004 we bought all of the remaining leftover 2.5 EFI engines in one swath and put a package out that liquidated them on the market. Right now we have debated doing something similar with another engine brand on the Pantera II or Pantera Classic models. The answer for most of your rigs (P3 & 200 EFI) was a 23 or 24 Tempest. We ran them on this set up with some moderate success. If they made a 23 Fury this would work, though tweaking a blade angle in reverse on a customization is not a good concept. It creates blade twist we dont like going backwards. Thus our answer to you is to try a 23 Trophy or a 23 Tempest. Do NOT put a set of wedge on this. It might help very slightly, though it is not the answer. The wedges were built in the mid 1970s to remove porpoise in hulls and adjust for OMC engines that did not have as much down trim as Mercury engines then. Wedges are for a boat that did not have or was not designed with enough transom angle, and some of the boats in recent years have been modified with wedges. The recent porpoising of two brands of boats has led to more recent popularity of wedges. We really dont think this is a good idea as they missed the design in testing on those brands and are adding modifications to tweak the errors out. To add something to improve performance is one thing, to do it to fix is another. Improve your performance and play with the propeller.
