i had a 2007 h180 with a tower and i find its missing power to jump up when you have 4 adults.i just got a 2010 h180 ss with the 4.3l and its alot better.good take off, strong and very quiet at higher speeds compare to the 4 cyl.i am suprised the 4.3l is better on gas than the 3.0l i had.i am doing the same trips with it and coming back with more fuel in the tank than the 3.0l engine.i had to check and yes the tanks in those years are are the same litres holding.

.if you will be pulling a skier or a tube get the 4.3l. trust me i being there.thats why i traded in the 2007
