I don't think the 135 has a water outlet like your 175 Daydreamer.
The 135 has a few more B-days under its belt.

My 90 Johnny has a T-fitting like you mentioned KrackerJack. The hose runs to a plastic fitting that snaps into a hole on the lower section of the cowling. Right there at the fitting is a restriction point that gets stopped up easily if you run through much sand/mud. I dropped it in the drink last time I had to remove it to remove a blockage. The small purple mister nipples found in the irrigation isle at Lowe's work great for directing the spray away from the motor and far enough out that it can be seen at a glance, if you don't want to drill a bigger hole and go factory that is.
