I've spent the last few weeks running a new to me 265 and pretty much all the responses so far are spot on.
They need a certain amount of motor trim to get that bow up out of the water or it bow steers quite a bit.
The 265 Express, IMO, is not for the weak at heart operator. You need to get/be somewhat aggressive with the way you run these 265's or they walk you all over the water. I was told in the beginning the 265 got better the harder you ran it. Now, after learning its quirks, I completely agree. Almost all of our days out on the water these past few weeks have been anywhere from 2-5ft swells, often as close as 5 seconds apart with confused seas and usually fast sometimes very fast current/s.
The first day or so running this 265 I pretty much hated it but then I started experimenting with different motor trim settings and when I started doing that my opinion took a 180. I ran anywhere from 23-33kts and most of the time 28kts, in the conditions I was running in, was my sweet spot. A few times just messing around when I only had a 2-3ft, spaced 8-10sec apart I ran it up to 35kts, and I was VERY impressed with how well it handled but at those speeds my fuel consumption with the twin 250's wasn't nearly as impressive.
Best advice I could give a new 265 owner is play with your motor trim and throttle settings, ALOT!! The more time you spend out on the water trying different settings the faster you will learn what works for you and where you like your settings for your conditions. There is no substitute for time out on the water.
