    Mercruiser 3.0L Points to DEI Engine

    you will have to define "digital electronic ignition"... If you meant to say "DDIS", that system pre-dates your engine (assuming its original ~ 1999), I'd suggest staying away from that ignition as getting those parts has become a real challenge...that said, if the engine is in good shape and...

    by itself, that distributor shouldn't be a contributor to your cranking/starting issue.

    vacuum advance unit on distributor = auto unit = extremely UNSAFE in a marine environment....if you don't believe me, ask you marine insurance agent.... I would replace it with a marine rated unit.... The big difference between the two rating classes is that the marine units are 'sealed' so...

    D6-370 shut-down

    i would check the VENT to the fuel tank based on your description. you can also plumb a vacuum gauge into the suction line feeding the fuel pump...

    Engine doesn't crank

    two more items you can check: 1) the neutral safety switch...ie make sure the shift lever is in N... & 2) Not always a good test....the wiring thru the harness to the dash and back to the solenoid typically won't handle the current required to close the solenoid consistently...and its alway...

    tell me that's NOT a capped off vacuum advance on the HEI distributor on your 302....???

    it would never hurt to prime the oil galley...that said, will the little resistance the rotating mass has, I wouldn't said it is essential at this point... I think it would be more meaningful to do the voltage drop measurements from point to point...first would be from + battery terminal...

    That is a good data point....guess the new solenoid will be the next item ...

    4.3 Mercruiser/ Alpha One Stalls when put into gear

    IF it is the lower shift cable binding up, the best repair is to replace it...anything you can do to it is only a band-aid. FWIW, the interrupter switch, when functioning correctly, only closes when shifting out of gear...not going into gear... And I'm pretty sure your idle speed is set too...

    another thing that came to mind...and I don't have a lot of experience here...is that since the outdrive was redone, its possible the issue is there...so it may be worth the time to remove the drive to see if the 'engine drag' is still present...

    Mercury 175 sport jet shaft/gear

    its NLA....and, very likely, low volume...so not too many sources at this point...a search engine is likely to be your best bet...

    Dielectric grease is an INSULATOR and should NOT be applied to electrical connections when they are made...applying that grease over top of a connection (after it is made) may help in excluding moisture. depends upon your batteries...newer technology batteries are more sensitive to charging...

    5.7L Captians choice carburetor engine in-line fuel filter replacement

    you didn't say which version....most come with a holley 4160....so you can likely find a 'how to' on you tube... remove the flare nut fitting to get the fuel line out of the way, remove the retaining nut (slowly), remove old filter and gaskets, replace new parts, tighten things back up...
