I am purchacing a 2005 Palmer Tiderunner 195 but haven't decided on what to power it with. I have concidered a Yamaha 150 HPDI 2-stroke, Yamaha 150 Four stroke, and Suzuki 140 Four stroke. I am an avid waterskier and fisherman so it is important for the engine to be able to get out of the hole quickly as well as idle for long periods of time without loading up. I was leaning toward a Yamaha 150 four stoke over a Suzuki due to the larger displacement of the Yammy. I have been reading about problems with the new Yamaha four strokes, however, and am a little concerned. Do the Yammy 2-strokes have similar problems? Will the HPDI be able to troll okay without the 2-stroke smell and loading up? Any advice or opinions would be appreciated.
