ebay has some trim and tilt units, most are going to cost 300-500 $$. I would use a factory trim system. They just bolt on to the inside of your motors mounting bracket. Most of the work is going to be electrical. Hooking up a switch and trim relays. Im not trying to knock those cmc units, but i tried using a setback on a jet unit and it hurt my performance. I would try to keep my shoe of my jet unit as close to the boat as possible. The further you get the shoe from the boat lets water inside the pump casing it to cavitate. therefore getting a factory trim and tilt would not set your motor back like a cmc would.
Having drove and fished in a boat with and without trim and tilt. I would recomend getting it. it makes things so much easier for fishing, trolling in shallow places, planing off, top end performance.
just my $0.02
