Black Max 150 starting issue

[DoctorCAD]

It has been really hot here this summer, so boating has not been on hold. It's not a lot of fun to sit in 100* heat on a lake with no breeze.

Because of that, my boat has only been started about 10 or so times this season, with the last time a month ago. Saturday, I tried to start the motor after charging the batteries and it won't catch. The primer stays firm, there is gasoline in the carbs, plugs are clean etc.

The odd thing is that it tries to start and then kicks the starter out. I think that if the starter motor could turn the motor over longer, it would fire right up every time. This will go on 10 or so times before the motor will finally turn over enough to run. Of course at start-up a giant cloud of smoke forms from the unburned fuel inside the motor but that goes away fast.

Once it starts, no problems, lots of power and nice even idle. Lots of smoke, but that's the way those 150's run.

I did a de-carb last time out and the motor runs a bit smoother, I may do that again.

Any ideas as to waht I can do to solve this?

Thanks

Is your enricher valve functioning properly?

I didn't use it, temps were in the upper 80's, Should I?
I thought it was only for colder temps, like a choke.
Never used the enricher on my Harley over 70 degrees

My 83 150 does the samething unless you use the enrichener too and it does not matter how warm the outside temp is......

I have a Black Max 150, and temperature has little if anything to do on starting procedure. Hold it in for 5-10 seconds before trying to start, then lift the cold start lever a little and start the engine with the key pushed in.

Don't have a cold start lever on my control box.

I will try the enricher next time.

I dont have to use the cold start lever, pump the bulb hard and together crank and push and hold the enrichener button until it's starts. Mine takes around 5 cranks and starts and idles smoothly with no cold start lever. It may take a few trys to find the right combination that works for your motor..

My 83 150 is like the rest. Gotta choke it first time! The rest of the day I don't need to.
