Info

Xtreme Performance - Holley Ultra XP Marine carburetors! Ultra XP Marine carbs are up to 38% lighter than our traditional race carbs, have fuel capacity that is 20% greater and other new features! They're available in Hard Core Gray hard coat anodized finish with Black billet for improved corrosion protection from corrosion in fresh water or salt water conditions. Holley Ultra Marine XP carburetors offer new features such as an integrated idle bypass valve that allows for idle adjustments while maintaining the correct throttle plate to transfer slot relationship, high capacity fuel bowls which feature 20% more fuel capacity to eliminate starvation, integrated fuel shelf to minimize fuel aeration and internal baffling to control fuel slosh. Other features include all aluminum construction, fully tunable billet metering blocks, billet base plate, adjustable secondary linkage and knurled (hand adjustable) curb idle screws. The new Ultra XP Marine models are built to exceed the Coast Guard standards and are J1223 Marine Standard certified. So, if you are hitting the lake for an easy cruise or some high speed fun, these new performance carburetors will meet and exceed your performance demands!

Features

  • Hard Core Gray with black anodized billet aluminum metering block and booster inserts
  • Contoured venturri inlet offers balanced airflow for increased horsepower

  • Knurled (hand adjustable) primary and secondary curb idle screws allow for easy idle adjustment without the use of tools
  • Primary throttle shaft capped to prevent entry of debris & contaminates
  • Stainless steel adjustable secondary link. Provides choice of 1:1 or progressivesecondary throttle actuation for ultimate control of secondary opening rate
