Hi David,
Should be plenty of power, our previous 340 was amazing w/8.1 horizons, got up on plane like a runabout with a big block, though WOT was about 61GPH and best cruise was only .07 mpg...Did not matter to us being inland, as we usually go 10 miles out and hang on the hook for the day..
I know we've been on a 360 over the years, just can not remember the layout...
Not sure if this is a first boat, a bigger boat or what, but some must haves on our previous express cruisers were (our needs, certainly not yours perhaps)...
1. Centerline Master
2. Seperate shower
3. Camper back (not slant back)
4. Genset
5. Serviceability
In a comparable look, our 3700 Maxum we owned last season, addressed all these issues...
Other than that, that's about it, though I've not been a fan of the engine room space on SR's, (we've owned 5) the trade is a bigger cabin, which we appreciated greatly.
Keep us posted on how you come out, it is a buyers market right now, though not a single dealer/broker will admit it.
If you're not trading, that gives you even more buying power!
Good luck!
Lou
