HULL OPENING CUT OUT
The pump to powerhead opening in the hull is the
most important factor to consider in a Jet Drive instal-
lation. There are three areas of concern:
1. Location (a) of the pump to powerhead hull cut out
relative to the boat bottom for proper ride plate
seal fit.
2. Dimensional control of the cutout - corner radii
(b), straightness (c) and size (d) for proper grom-
met installation, and corner radii (e) for ride plate
seal fit.
3. Flatness and thickness of the area around the hull
cut out for proper grommet sealing (see drawing
on next page).
