    1998 Mec 150 black max

    tha pumps were added for tha roundy round racing boys.. acceleration off corners and choppy water.. they jus didn't work out as they were supposed to.. they have no effect on idle circuit up or down.. tha '95's didn't have pumpers unless they were some kinda "left over" item merc wanted ta use...

    1998 Mec 150 black max

    pumper WMH carbs only lasted 2 years.. last of which was '92... they were a bust for regular boating use.. if your motor has these it is either not a '98 (should be WMV's) or they have been changed??? tha pumps can be eliminated without any repercussions to performance.. simply strip all tha...

    Is the high pressure pump constantly running..because when I test it is always is hot.. Is it not grounded or is it wired directly to the battery

    tha pump will only run with key on.. it should run a few seconds then cycle off if motor is not started.. it has a constant "hot".. tha + terminal will always show hot... its controlled (run or not run) by a ground from tha ecu...

    2000 mercury 200 2stroke efi possible ecu issues?

    find yourself a different guy.. tha "kill switch" circuit kills everything ign. related not jus certain things (3 of tha 6 cyl's).. if ya have 3 cyl. firing is gonna be either stator and/or motor control module (not ecu) more than likely....

    1989 xr4 150 that sat 3 years issues.

    As for that fuel pump it comes on with the key then goes off. Then start the motor and it runs when motor runs. shuts off when pressure reaches its max.. thats a good thing.. havin' tha 16 amp pretty much tells me it has tha vertical front half on it.. all horizontal front XR4's i've seen were...

    Regular maintenance - change just the impeller or entire housing too?

    tha only reason i suggested replace it all is 'cause it's not worth it ta me ta pull it again, time, labor, inconvenience ('bout 20/25 bucks difference) if one of tha "other" parts fails somewhere down tha line but ta each his own... like said, you cannot "always" tell if they are wore bad...
