I have an 1987 88SPL Evinrude. I replaced the powerhead with a remanufactured unit. I have this squeak, ticking noise below 1000 RPM. The old worn out engine ran a little rough but did not have this noise. Has anyone out there heard anything like this and have a fix ? With a stethoscope it sounds loudest on the intake manifold area but hard to say. I can also hear it when the engine is cranking over. I have put 10 hours on it and it runs fine. The replacement included block, crankcase, pistons and heads. I had to transfer everything else. Any ideas would be appreciated. Thanks.
