Well, It's not a Saguaro. Looks like a Sleekcraft to me, but the chines are different, and is that a delta pad bottom?

Omar or Ralph can probably ID it from those pics.

How long is it overall?
That's a berk 12JC pump you have. Perfectly fine, but looks in need of a rebuild.
Bad news is that trailer looks to be for a tunnel hull. It's gonna need some work to make it fit that boat, but not too overwhelming. Theres a few tandem trailers around pretty cheap that might make life a little easier/better for you in that regard.
