    Update on the Repower of the OMC 165 GM L6

    Okay, I found out you can only have 8 images in a post, so I'll update here. I'll save a lot of verbiage and replace with pictures, but here's the old motor in my garage, parts trashed off of it or removed, cleaned, prepped and installed on the new longblock:<br /><br /> <br /><br /> <br /><br...

    "Valve Lash" Adjustment - GM L6 250 cid...

    Okay, on my new longblock, it came with a note on one of the push rods to:<br /><br />Before installing the valve cover, be sure to check valve lash<br /><br />Uh... How do I do this? I read some in one of my manuals, but it didn't help much.

    New Oil Pump - Old Pickup Tube...

    Okay, how do I get the old pickup tube on the new oil pump? (GM L6 250 - '73 OMC 165)...<br /><br />I've gotten to a point where I have to figure this out. The pickup tube is/was "pressed" into the old oil pump, (and the manual mentions this), but it does not say how to get the new pump fitted...

    Volt Meter / Ammeter

    Anyone know if I can "switch" from an Ammeter to a Volt Meter? (OMC I/O GM L6 250). The old Ammeter has the connections of "S", "I" and "G". The voltmeter just has the "+" and "-".<br /><br />Hmmmmm...<br /><br />I've never really known what to do with the readings on the Ammeter but know how...

    Rust Removal from Manifold

    Before I get the new long block (GM L6 250 - OMC), I'd like to clean up the manifold. How can I remove the rust that is in there? There isn't a LOT of it, but I figured a cleaning would be in order...<br /><br />Flush it? Chemicals?<br /><br />Thanks!

    Oil/Water Boiling on top of my GM L6 205 Today :-(

    Took her out to the lake today to try to get stripers and got a few miles out, saw the temp top out and the oil pressure go low. When I noticed that, I shut her down and opened the engine cover. To my horror, I saw emulsified oil boiling in a pool between my Holley 4BBL and the valve cover...

    OMC Stringer 165 Shifting Problem... (Electric Shift)

    Took her out this weekend and found that when I put her in Forward, it seems like she's only "partially" in forward. I hear it "click" into gear (quietly) and she moves forward, but very very slowly. After 30-45 seconds, the louder more familiar "click" and off I go! It kind of feels like a...

    Tach not right...

    Ever since the batteries were wired wrong, (don't ask - he paid for new ones), the tach will not work right. <br /><br />I'm wondering if the tach is bad or since the poles on one of the batteries were reversed, could it have messed up the coil. Everything runs fine, but the tach is WAYYYY...
