My Father and I recently purchased a ned Lund Crossover XS 1875 (18' 10") weighing about 1600lbs. We are concerned that the prop the dealer has on will really limit our top speed at WOT.
Currently the boat is equipped with a Viper 20" pitch SS prop. To the best of my understanding this prop will likely get us to only around 45Mph? This seems awfully low considering our much heavier fiberglass boat could achieve 52Mph with a 150 Suzuki.
Can anybody please give me some advise on what prop to select prior to us picking up the boat as we have to travel 15 hours to pick it up! We ideally want a prop that is capeable of around 50Mph at WOT, good on fuel at cruising, and good for general use aluminum boats.
Typical boat use: 3 people, 2 trolling batteries. Occasional watersports including tubing.
Any advice is greatly appreciated!!

Your boat is compares closely with the 185 Alumacraft.A Viper is not the best prop for your type of rig. A Rebel with a 19" or 21" pitch would be a good starting point as would a 20" RX4.Engine height is critical for good performance so start with the 3rd hole mounting height. The 4th hole may even be needed but can be determined with a sea trial.Evinrude drivers ran an Alumacraft 185 last summer in 4th hole on the nationwide Edge demo tour and it reached 54mph with a 22Rx4 propeller.
Remember that most testing is trial and error and it is important to work with a dealer who is willing to work with you.
