More fun stuff from the cobalt manual. Lol

Yes I found this information. The reason I'm asking is because Cmatt mentioned that they came in 1.47 for sea level and 1.61 for Tahoe and I wanted to confirm what I have. I know the PO did use it in Tahoe. The gearing would require different props.

Hi All Revisiting this; I called Merc Cust service and it turns out I have the 1.47 gear ratio and will be using the boat in the Sacrament Delta. What size prop should I be looking for? 1999 200 with 5.0L EFI. I has a Turning Point 14.5x17p aluminum prop on it right now but I would like SS and possibly more speed.

So are you going to do any water sports or you just want speed?
Because your going to go with a 19 or a 21 ss prop. 3 or a 4 blade.
Mercury enertia is a great prop. I also used a mercury vensura (offshore) 4 blade prop. 3 blade mercury vengeance prop is a good cheaper ss prop. I take it this is a mercury alpha drive.

I may tow a skier once an a while but mostly just running from point A to B so speed is a priority. My thought is a 14.5x19 SS prop.

See if you can find a enertia prop.
