1984 115 VRO Push Choke in at High speed boat takes off

[brucehick]

Just had a new fuel pump put in, Old VRO one was showing signs of wear. Boat will not reach full speed without pushing the choke in I am going to replace fuel lines. What else should I do? It's so close to taking off.

Your immediate problem is a fuel delivery problem, which can have a number of causes, such as:
. air leak on pump suction side (bad clamp, cracked hose, cracked tank pickup tube, etc., etc.)
. malfunctioning anti-siphon valve
. plugged tank vent
. trash blocking tank pickup screen
. plugged fuel filter
. collapsed fuel line
. The most likely: Dirty carbs. Must be dis-assembled, soaked, blown dry. Remove core plugs before soaking, make certain all orifices are clear. See here for general guide: http://forums.iboats.com/showthread.php?t=299680

I agree with Wild pushing the primer button puts additional fuel into the engine. Time to clean the carbs.

Thanks for all the help

I figured it was carbs I am going to run off 6 Gallon tank with some seafoam just to be sure maybe I can get it loose. Short season in NE hate to have it at the shop for too long.
