Bravo basics in gearing
I apologize if this has been beaten to death already but I did a search with no solid answers.
My Bravo 1 originally had the 1:5 ratio but the previous owner changed it to 1.65:1. Is the gearing change in the upper, lower, or both? Can I just buy one half with the 1.5 ratio?
Also, does a billet top cap help reliability?
My Baja 272 is currently propped with the 1.65 setup but I just upped the power and figured reverting back to the original ratio would be easier than buying new props as I have a variety for different conditions.

Unsure yet, but it should be right about 600-650 total. I know a B1 is inadequate but have read everything from people running their 800hp with no problems to blowing them up with the stock 454 mag. I'm just hoping to get through the summer and sort that out next winter.

If the drive is off, you can count revolutions of the drive input shaft, compared to the prop. If it is a 1.5 drive, the propshaft will make 1 turn, and the input shaft will make 1.5 turns, or to make it easier to see,, for every 3 turns of the input shaft, the propshaft will turn 2 times.
