Just acquired a 89 176 in excellent shape with a 150 mariner mag II on it. 6'' jackplate..don't know measurement yet but will soon. Also running a 24" trophy. Is this a good setup?? Previous owner said would push 70...with light load...is this possible?? I figured low 60's but I've been a R&*(^r man and this is my first champion and can't wait to get her on the water..i've heard SOO much about their ride. I'll post pics soon...from the condition of this boat I stole her...just wondering other setups and what you've done, seen done, and experienced with this hull/engine combo...from the size of the boat and knowing what the old mercs/mariners would do should be pretty potent rig. I would think I could run a 25" with this small hull but it may be pretty heavy. Thanks alot and look foward to hearing from owners and previous owners..by they way...I fish alot...and have heard the trophy is where its at...although giving up 2-4mph to the tempest. Thanks again!!
