84-87 Force 320 question....
I have a 86 Force 320, looking for others with same hull with TRS....
what engines are you running?
Prop brand and size?
GPS speed and rpm max?
I have 420's with TRS, running 23P Mirage and get 64.9 at 5000 rpm so far, I am thinking this is all she has but wanted to compare with others with same boat....any info would be great!

My 87 with a 3" raised X and extension boxes with 454mags (365hp) ran just shy of 68mph (GPS).. I have 502's now with 450hp and so far it ran 71 gps, but that was with 24b1's at 5400 rpm's and 3/4 throttle.. The motors are suppossed to run at 5100 so I'm guessing with bigger props my boat will run somewhere around 80 give or take!!
