    Evinrude V8 will not run with airbox installed

    Hi all! I have an Evinrude V8, been told that it should be a '90 300hp, but the identification plate is missing so I do not know for sure. It is setup with a Holley Blue fuel pump and regulator @ 5psi, feeding directly to the carbs (no overflow issues) and running premix. The carbs are...

    Identifying a Evinrude V8

    Hi all! I have just bought an Evinrude V8. How can I indentify if this is a 250 or 300? The normal small alu plate with the "e300"letters" are gone. The heads looks to be marked 34079, maybe + a 7 at the end, if so, those heads are as far as I can find ?94 -> ?98 250 or 300 heads. Maybe a...

    Johnson 150 V6 1985 rebuild

    Hi all! I have an Johnson 150 V6 that started to run bad some weeks ago. 90 degree V6. It could cope with high rpm but would make very long time getting there and at all the wrong ignition advance values.
