GOOD NEWS. . . . The PICTURE UPLOAD FUNCTION IS WORKING !!! The tech folks at the parent company have been able to remedy the issue. You can upload pictures once again. Thank you for your patience.
just out of interest, what is the max RPM that the old evinrudes are meant to run? <br /><br />I know that later model engines can run to 6000, but my factory manual says 5000. (my manual is for 1971)
For the Big Twins, it's been 4000-5000 since the '56 30hp. I don't think they ever bumped up the 43.9CI engine, even late in the 70s.<br />I forgot to mention, the pulses are negative. <br />(and this has got me back on to that project. I just fitted the 4hp with a test lead. I've been meaning to build a "black box" so we can use a modern tach)
Well, it's just a hobby for me. So I'm a little out of my league especially with analog stuff.<br /><br />I'll post a new topic tomorrow with what I've got so far and where I would like to go. I really could use some opinions & advice from people who know this stuff better than me.
