Looking for some advice on setup for a Collins Mirage with a 280

[bteski]

I recently bought a 1996 four seat Collins built Mirage. It has a fresh 280, wizard pistons, Consumer box with raised limiter (Simon) but otherwise stock. Coned CLE 1.87 gear, Not sure why but this gearcase doesn't have a blowout ring, 10 1/4" jackplate, propshaft centerline 1 1/4" above the pad. last weekend ran 106 with a Drag 4 32 pitch @ 7500 rpm, Previous it ran 102 with a 32 cleaver not sure about rpm's as the boat was having electrical problems. All of the wiring & switches have been replaced just waiting for my GPS speedo & a new water pressure gauge to make it back from Livorski. My next test will be with a Drag 3 30 pitch would like to hit 110 but not sure what the boat weighs yet & not sure what to expect from a 280 with stock electronics and an alternator any thoughts. Thx Bob
