I had a Suzi DF140 on my 6.3 Ocean Pro and it was good for 40kts (just !!). It had been rumoured that this engine only produced circa 126 HP and I always felt that the DF 150-175 would be a wonderful engine on this hull.
The choice is yours, I have operated Suzuki DF 90, 140, 200 and 250 engines and have found them all to be reliable and economical.
