I am looking for some advice please. I have owned a small sport boat for years but I am now about to order my first pwc. I have decided to buy the new 2011 Gti but I don't know which motor is best. I have read that the 130 is comparable with the 155's low end torque and start up power but the 155 has about 5 miles per hour more top end ( around 60 as opposed to 55). Is this accurate? Also is the "power loss" of buying the 130 really worth all the fuel savings that it claims. How much difference is there between the fuel consumption of the 130 vrs the 155. I am hoping you experienced riders out there can help me out before I place my order. ( Oh...I will be towing ski tubes and pulling my kids on skis) Any advice would be appreciated. Thanks!
