Logically, they ought to use less fuel than their bigger block cousins but no doubt someone will correct me on this!

I have the 2006 Evinrude catalogue in front of me. Weights for the 25" versions are:

250 (3.3 litre) - 238kg (534lb)

200 (2.6 litre) - 194kg (427lb)

That's a weight difference of 42kg (107lb) per engine

In a twin set-up, the smaller block engines will be over 15 stone lighter!!!

I hope this is usful info!

Chris.

Thats one hell of a difference hanging off the transom!!!

We have a 225 on the demo boat - the SC1000 are the standard instruments and can be linked to any GPS with NMEA output. There is also the option of upgrading to the SC5000 (the instrument in the middle of the picture) which presents much more infarmation. The alternative as already mentioned is to go for a Navman GPS - some of their stuff accepts the Smartcraft interface and will provide an enormous amount of information as well.

plus dates on when they would be available were all over the place with nothing firmed and i did not want to be in a position of waiting till may/june for an engine and missing out on some fun

plus was not a big deal as i may go for building a bigger model at some time

Hugh trust me they are no thirstier and there no less reliable over the coarse of four or five days crusing in scotland along side someone with a 200 opti on the back of a 6 mtr. rib and my 225 E tec on the back of a 7.3 mtr we were doing on average 60 miles a day all through the rev ranges we worked out that the fuel consumption was pretty much the same and as far as reliablaty I know this is not a commen occurrenece but his compresser blow up just out side the harbour at Tobermory and Mr. E tec had to tow him 26 miles back to Oban the tecnhology is amazing even to the first time you turn the key there is cranking the engine over as the management system knows which piston is next in line for firing and the start is instantaneous very spookie

So if linked to GPS via NMEA output what information is esxchanged/viewable?

I've checked out the Smartcraft interface and it looks pretty comprehensive. Are there any other brands apart from Navman that are compatible?

With the sc1000 it is limited to GPS speed, and a couple of other things, with the sc5000 it is fully integrated, so that you have fuel to next waypoint, course to steer to next waypoint and so on - with the Navman stuff it is all on the one screen, so that is a replacement for the sc5000 and a GPS all in one - added to the fact the sc5000 screen isn't the best in the world and it is an expensive unit, I will probably be fitting a Navman unit to the 2006 demonstrator that we are building at the moment - with a Verado 250 on it!

If you go to the Navman website and look ofr the Smartcraft compatible units you will see the amount of combined information is extensive.
