Best Outboard Power for a 76 23'

[thedog]

I have a pair of 150 etecs on my 23, flat out I run 38knts after I switched to four blade props , this is a bit slower than the 3 blades I used to have on it
top speed with the 3 blades was 46knts but the engines were only turning 5000 rpm. working too hard
I like the efficiency of the engines they hardly burn any fuel, total last season
was 3-1/2 to 4 gallons per hour, running trolling ect. with no problems
I understand that a single 250 would do the same as I do with the twins
less weight on the back end,
