I bought a 225hp 1995 evinrude motor on a 21' Charger fishing boat. I have taken it to 2 different marina at about 600.00 a trip to tune and rebuild carbs. The problem I am having is it will not come out of the hole without first running the RPM up to about 800 and giving it full throtle. If it is below or above 800 it will die. I have repalced the pump up bulb and fuel filter. I have also purched a new SELCO manuel. One thing I have noticed when taking off the cover there is a 1/4" hose located at the bottom of the crancase that has a brass 90* fitting on it with a screen in it. This is not connected to anything and I can not find in the manual where it goes.I have decarbed changed plugs, check compression. It runs fine when it comes up on plane. Can anyone help me!
