I believe with the Pantera 4s that I have seen and the 1 that I sold, BCB was using a 25 Trophy I believe, now I read some others getting fantastic speeds with a Fury and the 200 Optimax, I mean they were Haulin the Mail, according to Rick and Ivan that boat as we discussed runs best with the 200 HO that you are working on, I believe Rick explained it as the hull design and Lower unit design simply Meshing, at least thats how I took his wording….As we spoke that boat and the Bay Cat were the 2 boats that simply knocked my socks off, the Pantera 4 for its size,agility,styling and Rough water wave taming, the Bay Cat for being able to run about 70 and being able to try and find your cell phone trimmed out across Norfolk Lake, that thing was killer……Tom You will have 1 of the Sickest BCBs Ever colored when were done with this bad boy, too bad you couldnt get that 225 HO on that back, I know its not needed but sure would be cool…..BrannonYour Signature …
