Over the last two years they have put a lot of different engines in the TXI in Aus, from the 5.7 320 hp to the 5.7 350 hp, some had the 6.2 410 monsoon, now you can get the new Malibu M5Di Direct injected Engine 5.3.
I like the new Nautique but 170k is way to much when you can get a fully optioned Prostar for under 100k. MC is making big in roads in Victoria and I give Malibu 2 years max before they go to fully importing the boats from the US.
