I had this posted somewhere else but thought it may be lost since there are so many posts and thought everyone would find this unusual.
I have a 1995 225 HP Evinrude that stalls and will only keep running if I try and keep it revved up. I've tried new filters and pickup. Then this happened today.
I was getting ready to remove the cover and was putting my hand by the 2 exhaust holes to make sure I was feeling pressure and it immediately cleared. Took another 10 minute run and it stalled again. I banged on the motor cover and opened and closed the hold down levers a few times to make sure it wasn't causing some sort of problem. still bad, I then tried covering the exhaust holes which forced the exhaust to come mainly out of the lower unit. I did this while I had the idle revved up enough to prevent it from stalling and this cleared the problem again and the RPMs came right up. I think I did this one more time and it cleared it again.
I guess my question is what is covering the exhaust really doing to the motor on a 2 stroke? Is it forcing the motor to have more presuure, which I believe is how the VRO pump works? I went back to the dock and did notice there was agood amount of 2 stroke oil on the outside of the VRO (fuel/oil pump).
