Need ideas to stop porpoising?

I talked w/the mngr of CapSante for quite a while yeaterday and he did an excellent job of patornizing me and saying my suggetion on a bow raising prop and raising the motor was expensive so, I can see they are not going to be any help. He did say that Honda does not like other mfg's props on their motors. Looks like any fix will be out of my wallet. Although he did suggest a whale tail or doel fin, said he has seen them om the big Hondas. He did say he would check on that and get back to me but I am not holding my breath. They already have been paid for the motor and installation.
