you need to go on ebay, look up ZAP two part liquid epoxy, setting time 15 or 30 minutes and use that…………….I presume the deck is timber………………if not and it is also abs, you need a plastic glue…..best is plastiweld, but make sure that the plastic used is hips, and not true ABS because abs is a different compound to hips and you'll need plummers mate plastic glue for water piping.
