I am working on putting together my SX order and have a few questions. 1) The lake we will be using has a maximum length of 25 ft for a pontoon from the forward most point of the pontoon to the aft most point of the pontoon as measured prior to registration. The boat info sheet shows an LOA, a pontoon length and a deck length. Do I need to go with the LOA which is the longest which basically puts me at a maximum a of 23 ft boat? 2) We want to be able to pull tubers/skiers and lake has a maximum speed of 40 MPH. Is a 150 engine sufficient? 3) What do you recommend for flooring. Is the basic good, or would you upgrade. Thanks!
