Supposedly the sexy surf fishing is still on, roosterfish and such. Ya might need a bigger boat to quote a movie.

I ran a 12' ugly stick and a reel the brings in 56" of line per turn, but when I was down it was low season (March) did end up having fun with a mess of salt water catfish. but that was just a bait rig and squid.
On the beach in Mazatlan it took 3oz to hold bottom, so at you would need a steelhead/salmon at minimum you usually need a 75 yards plus cast.
You can have fun though it is worth the hassle.
Hire a boat too, it's worth the pain, I believe there is a fleet right in Punta Mita I was there 14 years ago nice place, it was out of the way back then.
