Part # 17-810747 - STEM NLA

You might need to get a used carb and salvage the Stem, and likely the Spring under it

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 guts and little linkage off, block tha tiny hole at bottom of casting and fill with epoxy.. most high perf guys do this.

I doubt the Idle Circuit can go rich enough to cover the loss of the Accelerator Pump, without other modifications being made.

I doubt the Idle Circuit can go rich enough to cover the loss of the Accelerator Pump, without other modifications being made.

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 up or they have been changed.............. last year of "normal production" for pumpers was 1991.................. ya might search ebay for tha early wmh "pumper" for parts....
