Hi guys I have a 99 johnson venom 200. Boat has very little hours on it and not a drop of oil anywhere. Original owner said its always been hard to start, so after a yr of running batteries dead i called a guy out and he told me it is my electric choke. I can hear it engage when pushing in key and once boat starts runs great wide open etc rest of day. Only way I can get bpat to start easily is turning the little red knob on the choke the opposite way, let it run for a few then have to switch back or it wont run. Anyone have a solution? Its a pain in the rear to pull off cover and flip knob and then back once atarted every time I go out

Are you pushing the key in while cranking the motor over , yes or no ?-----If you are running batteries dead I would also now look at doing an inspection of the starter.----Or test the function of the primer valve.----When motor is running and you push in the key what happens ?----Does motor slow down ?

Yes pushing in while cranking. Once I figured out the knob on electic choke I have just been doing it that way and it fires right up. And yes after switching red knob back and its warmed up if I push in on key it chokes out and tries to die. It works but doesnt, why I am confused

Well it sounds like the electric primer valve is working.-----There is a wee filter in the electric primer valve.---Have a look at it.----And perhaps look at other issues to do with starting.-----Battery load test.---Starter motor inspection.-----This should be easy to figure out !

I replaced the whole electric choke with a new 1 and it does exact same thing as old 1 did. I figured would be an easy fix as well just hoping someone had ran into same problem and knew the fix! Thanks for the replies.

Obviously there is something else ( quick start ? ) wrong on the motor.----And why was it not made clear in post #1 that the primer has been replaced on this motor.-----Your mechanic should be able to figure out what is wrong with some simple trouble shooting.

If the primer is working, gas is getting to the cylinders. It is an easy matter to check compression and spark -- can buy an adjustable open air spark tester cheaply at an auto parts store, and buy/borrow/rent a compression tester there too. I would start there.

It has to crank over at around 200 rpm to start, along with strong spark and compression.
