I recently purchased a Javelin 379T 150 fast strike combo and the previous owner gave me a manual (looks like 6") plate with it. He said that it was on the boat when he purchased it but didn't like the way the boat handled and was told to take it off. I was debating about putting it back on because I was under the impression that the jackplate should help the performance on most boats. A friend of mine that used to have a 379 also told me to leave it off. He said the way the 379 hull is made that it handles lots better without one. He had taken the one off of his also. Any opinions? So far two say no jackplate..........
