The story begins with a 1993 Johnson 175 Fast Strike.I blew the motor 3 months ago, due to improper oil injection and a disfunctional alarm.I had the engine and VRO system rebuilt by one of my good friends, who is a Master Certified John/Rude mechanic and Shop Foreman at the largest Triton dealer in the U.S.The new engine runs better than new, but we can't get can't get the VRO system to work properly.Alright, here is the problem. The VRO alarm is going off and losing prime at the tank, I can run the boat for ten hours straight one day and it never happens. Then on the next day it could go off 10 times.Sometimes its at 
w.o.t., sometimes when I am idleing, sometimes at half throttle.When the alarm goes off I stop and pump the loose bulb tight and go again.I have been running this engine 50:1 for three months, because of this problem and its been back to the shop every week but we can't find the solution.Here is a list of new parts Oil Tank, Diaphram and Screen, and Oil Pump.The orignal oil line and primer bulb were not replaced but check fine.We have called Johnson asked everybody we know and can't figure this out.Someone please help.
