Not to sure what is included with the Yamaha package,but my evinrude I command is a very nice system. You have a lot of sensors that can be added to the system. Not to mention, the gauges are so easy to see at all times. But I also would not be without the power steering. Remember,build your 1st boat last!
When it was all said and done you would probably not have been happy with that upgrade anyway (assuming we're talking Yamaha). It's one of the smallest actual increases in power to the prop for a ridiculous premium difference in price. The reason is because of how good the 150 is (not the VMax version, I'm talking the regular grey version). The Yamaha 150 is well known to really be roughly a 163 where the 200 is 200 or possibly a smidgeon less.
