That's what we're getting at - similarities. The important thing to know / find out are what are the differences between the engines?
I have been told that the ECU is different. But at over £1200 to change it it's not good value.
I can see that my throttle butterfly doesn't open fully - does it on the 175?
What's the difference between a 150 and a 175?
An extra 25hp would be handy if it's simple, cheap and reliable to achieve.
