Free: Contests & Raffles.
If you can at least throw a 60 hp on it you will appreciate it. You will find you cavitat and loose power on corners while pulling a tube with a 50. The salesman needs to get out and test this personally. He may provide better advise vs. just trying to make the sale. You may be disappointed if towing unless just going straight.
You get over a foot more beam on the Stryker! And a much beefier side wall. You will notice a big improvement in how it rides in heavy chop. The down side to the Stryker is it still has a small prop limit and the extra weight in the beefier construction can make them handle like a floating slug. But you do get used to it and the extra room is a very welcome addition.
