I'm in the middle of this project myself. I debated back & forth a few times whether to epoxy the pumps or use the Blowsion bracket. Ended up buying the bracket...mainly because this is my first SJ build & didn't want to screw up the placement & give myself a clearance issue later in the assembly. Other than the cost, the other negative on using the bracket is the pumps sit about 3/8" above the hull liner instead of flush, so they won't keep the ski as dry. I removed the scupper on mine because I'm using that thru-hull for my dual cooling. I know some people don't like doing that because they feel better having a mechanical backup that won't fail like an electric part. My simple fix for that concern was to wire each pump on a separate fuse. The way I look at it is, even if one pump fails, a single 500gph on a 3/4" hose is still gonna dump a lot more water than the stock scupper on a little 3/8" hose.
Here's how mine looks so far...obviously the wiring isn't done & haven't yet installed the pissers & hoses.
square box on the other side of the shaft with a hose running through it right in the way of where i want to install it. Can this be relocated? If so where and how?
