We used the 250 DI last year for charter, used it for 250 hours. The main bracket broke on two engines, the engine rubbermounting broke, the tilttube broke, and the gear broke. We had to change the sparks twice as often as the comersal claimed. We had to by 400 l. of 2-stroke oil. That was two barrels. One thing is that it costs money, but we also hat to fill up our 8 l. tanks every second time we used the boat.
We also have a 225 four-stroke Yamaha. It has more than 500 hours on it, and no problem what so ever, Not even changed the sparks!
We sold the Rudes and bought two 250hp Suzuki. They do have more weight and maybe one or two knots slower, but to us it is more important to have a troubblefree engine, and also less noice.
We have not tried the E-Tech, so that might be another ballgame. But it still uses more plugs and oil.
The 200Hpdi is probably a good engine, but the 300 HPDI was a disaster last year, and the Yamaha - people did not help all thei customers. Ask Petrov!
He, by the way is also opting for Suzuki, about the same experience as we have with our 4-stroke Yamaha. He is running something like four Suzuki 250hp.
