I have experience running a new 46 w/ 1075's. It is very impressive. The 46 Cig is fast, we've seen 116mph. It is a lot of fun to run, and very predictable. The 1075's idle, shift, and are very smooth. The first thing I noticed is how the boat doesn't slow down like you would expect when you back off the throttles, it makes you realize just how good the bottom is. It is a big, twin engine, V-bottom pleasure boat, with cat like performance. There is a considerable difference between the 46' and 42' models, and their both very good. after you run the boat you realize how much technology has changed from the straight bottom, triple engine boats to the new 46. It is a vast improvement, faster with less maintenance and more reliability. It also has a greatly improved price tag. You could have this or your choice of any 3 of the classic triple 1000hp #6 drive 47' Apache's, 46' Cigarette's, or 47' Fountain's. 16 spark plugs or 72 spark plugs....Hmmm...I would probibly go for 16.
