I am putting some break in hours on my 350Qs port 8 hrs star 38 hrs. The previous had the engines rebuilt but only these hrs in 2 years. He did not have the props tuned which I will do in the next couple weeks. My question is as I work up to higher RPMs at what speed should the secondaries kick in on the Carters?? What speed should the 31 get up on a plane?

I'm sure this has been discussed but my search is not productive therefore: The secondaries will open around 3100 rpm. Depending on loading planing speed for the 31 will be 15 to 17 knots. Be aware this is worth every cent paid.
Thanks Tim. I get my new bottom paint and props tuned end of the month I will see where I am at. So far at 2,000 and 10 kts fuel consumption has been better than expected. At 3100 I'm sure the burn will be way different.
Tim is correct. 3100
Between 3000-3200
Yes that is what I am seeing … hit 18 kts today at 3200 with some bow down tabs…
