see my crystal ball was right. The HVS was pulled and someone did not how to set it all back up and phase then it correctly, then check cam angle with a real scan tool after the fact to dial in that spec. Merc is the same way. Not properly set up and phased - Will set alarm 100 % and even shut down and or will not exceed above the 2000 K to 4000 K depending how far off your NOT phased properly is out (for a jist).
for many years I have had to do so many of these thru out since 2001 because people think you can set timing with the HVS. - It is way past 100's of them as being out of phased. Like I said you can not set any sort of timing with the HVS. This all applies to - MEFI 4 and up and ECM / PCM 555 and PCM 09 and up and all E controls not using a true distributor - all marine side of course. just for a jist of the apps and set up. the HVS cap also becomes bad as 5 and 7 crossfire so a new quality cap and rotor is must. Start there first and see if that helps - it will not help and if not cured your HVS needs to be phased / set up properly. there is your fix = crystal ball |

do not forget new cap and rotor and a quality one at that. report back the results since I have sometime on this one. I always like to know how spot on I am or not.

Will Do! It is going on the Diacom today so I will report back with my findings. Thanks Again!

the winky blinky is not going to tell you crap. Such outdated way of testing and you will never fix anything with it. Also it is for use MEFI 1 thru 4 only. You do have MEFI 4 for the GXI - E. I strongly will have to say if you are working boats buy the scan tool techmate pro or the Diacom software. You also ned OEm service manuals to continue to work boats. The fuel specs are 8 psi + or - 4 psi for low pressure pump side and 50 to 60 psi for the high pressure pump side.
I would change the cap and rotor - for starters. Check voltage thru out and grounds. |
your welcome - the HVS was out ? That had to be your main problem for the warning horn and limited rpms ? Paint peels inside the carter fuel assembly just the same as Merc GEN III cool fuels. Common problem.
And at times will or can plug up the injectors. |
