Have had the Puma out several time now and can load and unload with no problem. She gets on plane at 14 MPH and from there ya gott hang on. The problem I have is getting on plane. I have tried leaving it right on level, trim down, trim down some more and also tried trimming up. I have a 275 Verado and a 27 Tempest plus with all the plastic pieces in it. When I pour the power to it, the bow goes way up and I am looking at the sky.I am not afraid of going over backwards but you cant see anything in front of you.At tips, pointers or starting points would be appreciated. I have had several other boats and dont ever remember having a problem like this.I know after doing things for a long time you dont even think about it. I am no where near that point yet.ThanksJohn
