300 Pro Max Done In...
Blew up our stbd motor on our 2004 30' SPECTRE:(
#6 injector leaned out and pushed the connecting rod through the side of the block! Has anyone else seen this? Why did this occur... If anybody knows where to source out a short block I'd appreciate the help! Happy Boating! |
ethanol fuel
had same problem w 300pm, it turned out the ethanol fuel didnt get along with the rubber in the low pressure fuel pump (the new merc fuel pump rebuild kit uses plastic disks instead) this in turn didnt feed enough fuel to the vst high pressure pump which leaned it out at high rpm -also check vst filter.

Thanks:) Not runnin' ethanol fuel but, will check the fuel pump pressure and the VST high preasure pump as well...
Looks like a bad injector though??? |
i had diamond marine blue brint the injectors on my 2003 300x's and it made a HUUGE diff in idle and cold start manors

We've had some idle issues! It likes to cut out obviously when cold & when shifting. A Mercury Rep told me to run their Quick Clean. I think I'll send the injectors out to be balanced! Do you have their contact info?
Thanks, |
