Yes, I got the boat from NJ I was looking at. It's on Lake Norman now, in North Carolina, and will also be seeing time in Tampa, FL. I think the props are Mirage Plus but I'm not by the boat right now to 100% confirm. Drive gear ratio's I'm not sure. How do I check that?

Might be easier to pull the coil wire or plugs on the coil, put in gear, then jump the slave solenoid. Crank it over several times counting the prop and the crank
Edit: make sure to feed the drive water when doing this, no reason to take a chance

My only concern would be bumping it exactly one rotation. A 1.65 gear could be confused if you were not exact IMO. I'm not a mechanic just someone who has been through Tec many times in APBA LOL

1997 Scarab 29, Twin 383 Mercuiser Mags (350HP each, stock), Bravo 1's with 23P Mirage props spinning out. I am only getting 65-66 mph @ 4,900 RPM's with drives out, tabs up. Shouldn't this boat be going faster? This model supposedly does 67-68 mph with stock 350 MPIs which I believe were rated at only 300HP vs the 350HP of my engines. Suggestions on getting more speed? Different props? I feel this set-up should be going 72-73 mph.

You can count the teeth on your gears if you take the drive off or put motor at top dead center on the timing mark, put in forward gear, mark you prop location, rotate the motor with a breaker bar one full rotation, see how far your prop traveled (should be 1 1/2 turns) That's a 1:1.5 gear. That's how they used to tec our boats in APBA Factory classes. Don't forget a 1.65 gear is pretty close.
