I have the 2247, 2847 and 2849. At close to sea level I would recommend the 2849. I run at about 1500 ft or less and the 2849 works best. Although the 2847 with a bit more cup might be the winner. Still looking for a shop that can add cup. 2847 is very close to the 2247 just a little better hole shot and a touch lower revs. I normally run 300lbs lead in bow 100lbs under each bag and a crew of 6 or 7 adults, but I have had over 10 with no issues. With a large crew i run all 500 in the bow or remove the 200lbs from the stern.
