VesselView on a 175 Optimax?

[TSR6]

Hello!

I have a 175 Optimax, Model 1175P73EY, and long story short - the boat itself is older and re-engined in 2013 or 2014, and I only have Fuel Level, RPM & Trim gauges (fuel level needs a new sending unit - so technically it doesnt work). I thought that VesselView Mobile might be a good substitute?

What would be helpful for me:

• Fuel Consumption - How detailed is this? (aka... can I find a sweet spot for longer rides for the best economy vs. speed more in that 38-48mph range - we have a fishing trip that we go on where we do 50-100mi on the water each day.)
• Water PSI - I honestly don't know when the impeller was serviced, it pee's fine - but this should give me an idea, right?
• RPM's - I suspect the boat's RPM gauge might not be the most accurate
• Fault Codes

It's totally app contained, correct? (No cell service needed? We do fish a lake that has zero service)

Someone had suggested I check to see if my engine was compatible with VesselView mobile, but I thought they all were after 2006 or so?
