the graphs are indeed indicational.
PP has 3 (in general) versions:
- classic (magnet timing and optional switch), the ONE line display
- stargazer (magnet or GPS), multi line display
- Stargazer + Z-box (GPS, no magnets, ZO simulation, with accelerometer) --> this is the one I compare with ZO !
Then, throttle: cable or wire:
- Z-Box with drive by wire is as responsive as ZO (z-box with cable is not)
- Drive by wire also means: fuel injected engine (far more responsive than carburator)
- Any cable throttle is just slower (always)
- This means approx. a 2006/2007 or later model boat (throttle-by-wire got introduced during these years)
ZO is only available on drive by wire boats. (no retrofit on cable throttle)
Upgrade or not:
With Cable throttle:
- you have one option: PP
Wire throttle:
With PP already installed and multiline display.
- z-box is plug and play (DIY-15 minutes) and far less expensive
- PP has excellent support
- or replace with ZO, more expensive to buy, more expensive to install (no DIY)
- CHECK with your dealer if it works on your boat and engine (mine needed a NEW engine cable loom)
- ZO is 99% factory installed and their support.....lets say it took me a "while" to find out if and how it could be installed in my boat.
Nothing installed:
- Both PP z-box and ZO would work (but ZO with installation is far more expensive than PP z-box). AND for ZO CHECK if at all possible in your boat.
