So I am looking to buy my first inboard and am looking for something like a 07-09 XLV or possibly a LSV. I also love the Supra 21v or 22ssv. What I am finding is that most of the boats I find for sale have the 325 HP engine. I live in Salt Lake City, Utah and most of the lakes are about 5,000 ft. in elevation. I talked to the dealer here in town and he said that he would definitely look for a 340 HP engine due to the altitude here. Maybe the 325 would be ok for a little smaller boat like the LSV or the 21V but he has me worried about not having enough HP, especially for a bigger boat with 8-10 people onboard. I would love any thoughts you have. Thanks in advance.
