Triumph owner here seeking advice on jack plate.Can y'all help??

[geoboom]

I am a new owner of a Triumph 190{18'6"}bay boat.The boat is powered by a Evinrude 90 FICT.The previous owner had a hydraulic jack plate on it but the dealer through which I had gotten it took it off.He said it had a blown cylinder but I think it was because it voids the lifetime warranty on the hull.Anyhow,I was wondering if a manual plate was in order.I have been looking around at some other guys performance and I think I am way low.Plus I go in some shallow water fishing.I am getting 31mph @4500rpm.Please help.Plus this is a killer site for sure thanx-Geo

Did the dealer take it off after you paid for the boat ? Also a jack plate will definitely help you thanks.
