Questions regarding re-power on 13' Whaler

What would the performance difference be between the older 35 Evinrude and a new 25hp Mercury 4 Stroke? I have also been looking at other 4 stroke engines and wanted to know if the weight difference is going to have a major effect on performance. These are the weights of the various models I have been looking at: Existing 35 2 stroke Evinrude - 121 LBS 4 Stroke Engines 40HP Mercury - 210 LBS 25HP Mercury - 157 LBS 40HP Honda - 205 LBS 30HP Honda - 174 LBS 25HP Honda - 174 LBS 40HP Yamaha - 183 LBS 40 HP Evinrude E-Tec - 240 LBS *** I was surprised by this as Evinrude claims this is a lighter weight engine compared to their 4 stroke counterparts.

The boat is rated for 40hp and that to me is a better choice. I don't think a 25hp would be enough for me on my prior 13'.... I had the same motor you have on your 13' and I wouldn't have wanted any less.. Maybe someone else here might have that Yamaha engine on their 13' and can tell us more... Unfortunately, the E-tec 40hp has the same block as the 50 and 60hp.... That's why it is so heavy.
