Hello all. I have been fighting mightily to get this engine working reliable for a trip that is supposed to start as soon as next Wednesday, but things are not going well at all.
I have the 3 cylinder 50 hp evinrude , 1996 Just replaced the water pump, rebuilt the 3 carbs, and fuel pump. I think this originally used the VRO pump, but previous owner has swapped that out for the more standard triangular one.
Big picture, I don't trust this engine, and am about to do some sailing in unfamiliar places, so unreliability is not an option. I would hire someone in my area to do it, but I can't find anyone.
I did have it running today, but only barely. it was crazy rough at idle.
I have a few questions.
First one, and the biggest. - the motor is about .. 20 or more degrees off of plumb. The way the boat is made, I can't lower it all the way down when it is on the trailer. -- there is fuel that leaks out the front of the carbs. when I have the solenoid open it is especially bad ( I am testing it with out the airbox on the front). Is the fact that the engine is tilted back (Carbs are tilted "forward") an issue?
second , I was getting a leak from near the pump . the fuel seemed to be accumulating around the top of the hose that comes from a sport with a blue port , just behind the carb of the lowest cylinder. this is the hose, that I think uses the pulses from the crank case to power the pump. I have no idea why there would be fuel coming out of this hose. was I wrong. is the fuel leak really some where else and only appearing to come from that location? It would not surprise me if the fuel pump was leaking. They give this tiny gasket, that has less then 1mm of tolerance, and I had a hell of time installing it. any other thoughts on the fuel pump situation ?
lastly, once I installed the new water pump. (the part numbers seem right, but new one has 6 legs, and the old only had 3), I noticed it was way way hard to spin the drive shaft. Is this normal? The old one was all cracked, and "set in place" with teh arms bent, and the new one of course is much more "springy", thus harder to spin.
The unit will create a water steam, though it seem to work best at higher rpm, at idle there is less water then I thought there should be.
the unit did run today, for a few mins.. so it isn't blown up, but it does run very very poorly. Any sources you can point me toward for tuning it up ?
