    4.3 Mercruiser fuel supply issue

    That's completely insane. People make fun, but that's why I kept the old boat. Mechancial fuel pump from Carter, marine version, don't have to buy from the robber barons at Mercruiser or VP, $50, they last a LONG TIME. Can be bought at Jeg's or Summit Racing. Carb rebuild kit, the best...

    5.0 GXi oil extraction

    Honestly that was the only thing I could think of, I have never had that problem with my engine which uses a similar system but like I said earlier when I replaced an old (30 year old) mechanical fuel pump, there was some sludge build up inside the pump, the part that was inside the engine...

    Volvo 5.0Gi winterizing

    Whenever you can get those plugs out what I do is coat the threads with either Evinrude triple guard grease or Evinrude gasket sealer. I’ve never had one seize up even in salt water.

    5.0 GXi oil extraction

    The other thing you could do VERY CAREFULLY is to use a heat gun to heat the oil pan to about 100-125*F that may make it easier. 50* I don’t t think you can suck out oil. I have done this twice; once was when my engine had leaky head gaskets & had to change the oil 3-4 times to get the water...

    5.0 GXi oil extraction

    I have the same set up on my old OMC 4.3 in fact I think that Volvo adopted OMC’s design during the joint venture between OMC & Volvo. I have never had trouble sucking out all the oil in the pan with the Topsider vacuum pump & the garden hose fitting. I wonder though if an engine wasn’t...

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

    There is a Holley build # on the air horn that will tell you exactly what it is. The 4160 also came in different CFM ratings. The other pretty definite sign vs the 4175 is that since the 4160 is a square bore carb there will be a square to spread bore adapter between the square bore carb &...

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

    First 2 pix are a 4160: this is a 4175 (Spread Bore) The 4175 Spread Bore was intended for a replacement for the spread bore Rochester Quadrajet However, my experience with Holley vs Rochester, the same engine with the Rochester ran consistently better. Holley's quality control as of late is...

    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...

    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...
