Donna, we are back in the air! So fun to hear that 550 and feel its power. The climb performance is amazing for sure!

I’ll always be grateful for all you’ve done for me. Thanks for being so thorough and making sure everything was planned out.

I will try to give you updates as time goes on! Thank you so much for everything

The Davis conversion to the Continental 550 with the Black Mac 88″ prop was the the best investment I have and could have made to my 1976 Cessna 185. The plane with is now turbine smooth, the performance is night and day difference. On floats especially it is almost instantly on the step upon full application of power, where as the old engine would chew up a significant amount of water trying to achieve same results. I am able to operate in smaller lakes with a larger safety margin than before. In cruise with the power pulled back to 22.5″ squared I see the same fuel burn I did with my Continental 520. I could not be happier. Donna Jones was great to work with, she made all the coordination through my mechanic shop and the installation / shipping to Alaska was painless.

Just wanted to give you an update on the Skydive Fargo plane. They are very happy with the climb performance behind the new engine. They are able to take a full load of 5 jumpers up to 12k almost as quick as the 182 with a 550, 3 blade prop, and extended wings can take 4 jumpers up. It for sure made a big difference from the tired run out 520 they had on there. Thanks again for all of your help with the swap!

I finally flew 9385N this weekend and what a treat. The engine prop combination on the Skywagon is absolutely silky smooth. Both times up Trued at 160 knots at 25 squared at 18.5 GPH.

Very happy with the outcome and just wanted to say Thank You again for the time, advise, and attention for pulling everything together.
