Greetings. 1. Performance feedback: Our first C-Dory was a 1991 22' cruiser with a Johnson 70 and kicker. Second C-Dory was a 2007 22' angler with twin Honda 40's, whose total weight approximated that of a heavy 4 stroke single, or a lighter single/kicker combo. There was absolutely a difference in handling between the 2 setups: With the 70 the boat had a light, nimble feel and it was easy to get the bow down when conditions required, but I often wished I had more reserve power. With the 40's, the stern seemed firmly "planted" in the water and the bow rode higher. Ended up installing Permatrims on both 40's, which really helped handling at speed. With the 40's, my top speed was higher and overall the boat was more powerful, but had a heavier feel about it. It was suggested to me by the dealer that the best weight match for a modern single engine with the CD 22 hull was the E-Tec 90, which is apparently a fine engine, but I could not bring myself to choose a 2-stroke after years of using 2 cycle oil on previous boat engines. 2. Personal opinion/bias: If I were selecting a new single main engine for a CD 22 it would be a Honda EFI 90, Honda being my engine of personal preference. I personally cannot see needing any more than 90-100 total HP for this hull, or wanting the extra weight it would add, though some have gone higher and report satisfactory results. Good luck with your repower. Mike.
