So when a 150/150 is 150 pounds over mtow
For future reference, keep in mind that there is a 150/150 conversion which legally raises the gross weight by 160 pounds and if you stumble across one of those......life goes up from better to good.
My M model has this and the gross weight on Mighty Mouse is 1,760 pounds.
Another option to think about is the 152 which has a gross of 1,670 pounds.
The stock Lycoming is around 110 HP but if you find a 152 with the Sparrowhawk mod, you're up to the 125 HP mark.
This isn't as good as a 150/150 as that level of enthusiasm is tough to beat but it's superior to the stock 100 HP 150.
Decisions, decisions, decisions......
