If I know I am going out in big seas and carrying 1000+lb loads, I put on the 15P Mirage. It gets the job done just fine. Honestly I hate fishing in a 23ft boat with 5 passengers on board . . . there's not enough space.
If you are sinking $14000 into a inline 4 200 and a v6 250 is $18000 then you might aswell get the bigger one.
I'm gonna put a 150 on the 23 just for Kmoose.
