Highly recommend the Fox Marine engine gateways! It will transmit the calculated flow from engine ECUs. I've thought about adding flow meters to the fuel lines for greater accuracy, but when I do a compare of what the ECUs (via Fox Marine Gateway) say is the fuel rate and the amount I refuel...
Quick prop question... for those with 7.4s... what are your prop specs and are you happy with their performance? I'm running 20" diameter x 25" pitch 4-blades.
Radar install and possibly autopilot... just can't decide if I'll get enough use out of it to justify the cost.
For those with Radar, any preference/guidance on the best angle for the Radar Mount? 3, 4, 5 or 6 degrees? I know she rides bow high... so thinking 4+... but would appreciate any...
Update... because the RPMs would drop and fuel consumption would increase at the same time... it was determined to be an ignition issue. I replaced the plugs, wires and distributor within the last year... so that left the ignition coil. I swapped out the ignition coil for a new one and we’re...
Cliff,
Thanks for the additional details! The batteries are brand new as of last year... two per engine and identical across both Port and Starboard. But, I will absolutely watch voltage fluctuations on the next run and see if there's something funny going on when the surge occurs.
Thanks...
The plugs are within the year and the wires in the last two. The injectors have not been changed during my ownership. May check to see what those cost and if a swap of them all makes sense for good measure.
To be a bit clearer, the ECM reads a heightened fuel flow when the surge is...
I am hoping someone with much more experienced than I can help diagnose a problem I'm having in my port motor... a 1997 Mercruiser 7.4 MPI.
Engine is generally running very well... starts right up... idles smoothly at 600 RPM... consistent throttle response through the power band... etc.
The...
