New to the forums and have tried to do alot of research online and everything brought me to this site.
I purchased a new to me boat this past november and it has a 1997 200 Johnson Oceanrunner on her. It seems I have a couple of problems. After doing alot of searches on the "cold start", I can't seem to get it figured out. The process I do is first pump the primer bulb til hard and then turn the key to "on" w/o starting. I then push in the key for 8-10 seconds to prime and then try to start. The engine never fires on the the first many attempts and i sometimes have to wait 5 mins before trying again and after a few mor tries then it finally fires up.
After each try I do check the primer bulb and it is still hard or I have to barely squeeze to get hard again.
Now, once it fires up and gets warmed up everything is fine. I can run it, shut it down and then it will fire right up. The cold start issue is very bothersome especially at a busy ramp
My other issue is alot of times at idle or just barely in gear, the engine will just shut down. It will fire right up but will shut down again if i don't throttle up a bit. Is there anything specific I should be looking at to fix these issues? This is also a problem at a busy ramp when trying to put the boat back on the trailer.
If it helps, according to my maint log, I replaced all the plugs on 12/10/08, gapped to .030 and replaced the starting battery on 1/23/09 and the house battery on 3/14/09. I also replaced the fuel/water seperator on 4/17/09.
For what it's worth, I am new to owning my own boat and know very little if anything about engines. When I brought it to my local Johnson mechanic back in November all he did was charge up the batteries and he said it fired right up for him and the next day when I picked it up it fired right up again. The batteries were completely dead and would not hold a charge and that is why I replaced them and when charging them after every run they are holding their charge.
Oh BTW, the mechanic also said the VRO pump was bad so we bypassed it and I am now adding my own oil to a 50:1 ratio.
Sorry for the long post and thanks for any replies.
