This is exactly what I did....here are the results:
Stb Port
115 100 95 95
105 100 88 95
95 90 80 85
Also, the Port engine beeped once every ~30 seconds.......what does that mean?
Water temps didn't seem increase much.....stuck thermostats?
See how the water was coming out of the engines: between the lower unit and the mid-section. See video:
Another question: the charging system didn't appear to be working on either engine: do they not charge at idle?
If you look at the seam between the midsection and gearcase, you will see slots that are supposed to let cooling water exit.
Engine should have Quick start system where cold engines run at 900-1100 RPM until warm. Then idle should settle down to about 500RPM. Difference is noticeable. If that is not happening, I would check the 'stats.
Engines should charge a bit at idle. At 1200 RPM you should see 13+volts.
Thanks Chris........I don't have the boat home yet!

Did some research here.......possible low oil?
What about these gauges? The (2) the lower gauges next to the tachs.....I thought they were temp gauges........are they presure gauges? They did increase/decrease w/ the RPM's.
If that motor has plastic carb bowls, look for cracks. Motor can be run w/o air box. Source up some new spark plugs. They can be had at auto parts stores sometimes.
