Hello

my '76 V-4-85HP choke solenoid does not work any more at least I cannot hear it(solenoid) as before when I pressed the key switch. My question is, does the choke play a vital role when the engine is running? My engine starts fine with out it "ice cold." and starts fine after its warmed up as well. My engine cannot maintain WOT for more than ohh 7 seconds or more; it seems to be lacking fuel......the tanks/lines have all been changed. engine acting the same on new fuel pump as well as the old one. Frustrated...any thoughts??? and no the fuel lines have no leaks and I am not running 1000' of fuel line from tank to engine. 89 octane fresh fuel. thoughts???
as always your suggestions are appreciated..
Sincerely
RD1

If you don't need it to start the engine, I guess it's not necessary. You could check the voltage at the solenoid when you push the key in to find the problem.
It almost sounds like you might have some restricted high speed jets, when was the last time you had your carbs overhauled.

Sounds like carb/s running out of fuel for whatever reason. Thinking that fuel pump has been replaced by reading your post, leads me to believe it's a carb related issue. Plugged high speed circuit, float/s out of adjustment. Post back and let us know.

As a follow up, it was the choke linkage causing issues on the lake bouncing around and NOT in the test tank back at my mechanic's shop who ran the motor WOT for 25 minutes with out a hick up; the choke was engaging after the motor was warmed up; after a carb cleaning and choke linkage adjustment, I ran her on the lake WOT back and forth twice with NO ISSUE. Happy Boating!!
