    1990 5.7L L.E. OMC Cobra - Various Questions

    For the carb, it looks like a 4160, judging by the fuel inlet, the 4175 I think had a different style inlet, there is a # stamped on the carb air horn (go over to Holley.com) that will tell you exactly what it is and what parts fit. Looks like you have a conventional distributor, lucky it's not...

    1990 5.7L L.E. OMC Cobra - Various Questions

    https://www.crowleymarine.com/ you can look up what is listed for your 1990 OMC sterndrive 5.7 liter V8 here but basically, there are few options, all the 5.7s that year seemed to have the Holley 4bbl (looks like a 4160 to me judging by the fuel inlet) There appears to be 2 possible distributors...

    1990 5.7L L.E. OMC Cobra - Various Questions

    Yep I checked, it's the cone clutch Welp, what I'd do is buy some impellers, impeller housing gaskets (be careful with the housing, it is NLA) and other maintenance stuff that's available still. The impellers and gaskets are still available. Then just run it, when it needs something you can't...

    1990 5.7L L.E. OMC Cobra - Various Questions

    1990 was about the time OMC & Volvo switched from Rochesters to Holleys so that could in fact be the OEM carb. That fuel line looks like the factory steel line used on the Holley carb so it wasn’t added later. You can take that model # that starts with 57 and plug it into Crowley Marines OMC...

    installing a remote oil filter set up, got a question....

    Did some more research to see how Merc packages their remote oil filter kits and the ones I could find, do not appear to add a different bypass valve, or adapter for the V8s Then looked at how Crusader does theirs, the ones with no oil cooler are like Merc's no different bypass valve, however...

    Looking for a different distributor than my crab cat dist.

    Bow sitting high

    It looks to be sitting very different in those 2 pictures; in the first it looks too low in the stern but in the second it looks more level….

    Every title is not in seller's name

    In a state that titles boats I’m thinking you might not actually legally own it unless titled in your name. If you don’t legally own it; can you legally sell it? In NY boats & outboard motors are titled but smaller boats and trailers are not.

    installing a remote oil filter set up, got a question....

    Makes sense, but unless you know if your filter has a bypass or not, in the end you still may not have oil going thru the filter. I'm wondering if you can look up oil filter flow specs, would that shed any light on this question? Are they all the same, or are there differences? Does the length...

    Pumping out oil from dipstick

    That will work too, but the garden hose adapter allows you to use a larger diameter hose.

    installing a remote oil filter set up, got a question....

    Some filters have a bypass valve but some don't. Probably the majority of them do. Since the GM small block V8 as always had the oil filter mounting pad with the adapter & the bypass valve staked in it, you could use a filter without a bypass, and it wouldn't cause a problem if the oil filter...

    454 vibrating and breaking starter bolts

    If it was smooth when you got it back think of what could have changed…could there be an engine miss, cracked distributor cap, high tension lead with too much resistance etc. First I’d go thru it like auto shop 101 tune up…The balancer slipping is possible but not super likely…

    Pumping out oil from dipstick

    Actually on OMC/Volvo engines the dipstick tube is attached to the bottom of the pan with a banjo bolt style set up. If you use a garden hose adapter on your oil vacuum pump (female fitting; the dipstick tube had a male fitting) it works much better than the small plastic tube down the dipstick...

    454 vibrating and breaking starter bolts

    If Merc doesn’t sell it any longer check Summit Racing or Jegs It’s actually a GM part

    454 vibrating and breaking starter bolts

    The starter bolts can break if they are the wrong length (too long) and the old direct drive starters usually had a brace on the front to stabilize it. The bolts you use must match whatever starter you are using.

    In need of parts (and/or part #’s)…

    Even a small hole will cause those problems; you probably should replace the gimble bearing & maybe the ujoints. I\Os need a lot of regular maintenance… Impeller every 2-3 years depending on use Bellows on these can last as long as 10 years but some don’t due to storage (keeping the drive up...
