The other day, I was trying to get the boat on the trailer and had to tilt the engine up. I noticed under full power the engine wasn't tilting which is unusual. I never noticed it not working correctly while moving throught the marsh. I usually tilt and trim the moter serveral times a trip...
I noticed that my system isn't charging the battery. I first noticed it on the GPS system which monitors voltage. I had another rectifier so I just replaced it and was getting 14.5v at the ramp for a quick test. I took the boat out today and noticed everything was fine (30 minutes) then no...
I have a 1990 Evinrude 150 with a VRO2 pump. The engine was rebuilt last year and running great. Just lately, I have been having an issue at high rpm 4900 - 5000, the engine will start to pulse. If I squeeze the fuel bulb the engine runs fine. I have changed the fuel bulb, checked the fuel...

After idle is adjusted I move to the cam follower adj - this is where I get a little confused. As I understand the book, when you move the throttle, the first mark on the cam follower should start to touch the carb at 7 degrees. If I set that correctly and go to full throttle the carbs don't...
