    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    I'm honestly not sure if the pump is or isn't always below the water line or if the pump does or doesn't have a small amount of self priming ability but I take your point re priming. Just going on memory which could be wrong I seem to remember the water inlet port on the leg being around level...

    I think you mean the pump can't self prime but is normally below the water line? In that case would the bin idea work if the level of water in the bin were above the pump? Even if I don't go with the bin idea (I'll decide after reading your answer) I would (like you) want to prime the pump...

    Thanks for the carb rebuild info. Would prefer a 4bbl but I should make sure it runs before doing any mods. Early in the rebuild I considered swapping to aluminium heads and fitting a closed cooling system, I'd expect doing that along with the 4bbl would make a lot more power. I mean feed the...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    I like the simplicity of a carb setup but I convert vehicles to run on LPG (propane) for a living so I'm clued up on fuel injection systems and would like the extra 20hp and better fuel economy fuel injection might give. That said I suppose given the age of the components a carb setup stands...

    You're right it doesn't cut the ignition during shifting, no ESA fitted. I was probably overthinking the coil wiring, thinking about it now I'm pretty sure I've got the ignition wires connected correctly. Just didn't want to risk blowing anything like the electronic ignition in the distributor...

    Thanks for all replies. Gas fumes as in fuel or CO? That reminded me I may want to fit a new bilge blower and check routing of the blower ducting. The existing blower sounds like it has bad bearings but may just need cleaning out. There was a portable CO alarm fitted in the cuddy but its...

    Thanks. This is a 1996 OMC Cobra / Ford 302 / Volvo SX, is the wiring the same?

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    My second post this evening, I asked a few questions in my last post. I forgot to ask about part numbers for the 3 x V belts on my setup... I watched a Youtube video of someone changing the belts on the same setup as mine and he mentioned 3858462 is the PAS belt, 3852348 (I don't know if...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Got a bit more done today, fitted the starboard side exhaust manifold, riser and rubber exhaust pipe. Still haven't fitted the alternator but glad I didn't, seems it's wiring would be better routed from the other direction to the way I currently have it connected because when I put it in...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Is it better to fit the ancillaries (raw water pump, alternator, pas pump) first or fit the exhaust manifolds first? I don't know if fitting some stuff before other stuff prevents access to bolts etc. Recently fitted the rocker covers properly, I lifted the engine in with the rocker covers just...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    I was relieved to dig out the socket. As it turned out, it wouldn't have hurt anything where it was but I didn't know that before I found it, thought it had fallen between the coupler and housing where it could maybe have caused damage. It makes sense for the engine hour meter to connect to...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    I think I've found out where the wires are supposed to go by looking through pics I took before and during engine removal... Both purple wires to the hour meter, the brown to the blue Seems the first pic even shows which way around the 2 wires connect to the engine hour meter...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Found it with the borescope, it had fallen down the hole I'm shining a torch at in the picture below, got it out with a magnet pick up tool :) Since then I've fitted the wiring to the new alternator, confident I got it right. Tightened the J clip on the water inlet, connected the water pump...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Just dropped a 5/16 1/4drive socket I was trying to use to tighten the J clip holding the raw water pump pipe to the rear of the transom stuff into (I think) the area between the coupler and the transom stuff. Going to try to use a borescope now to try to find it and fish it out with a magnet...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    I was thinking along the same lines as a nut underneath and something around it (maybe like a jubilee clip) to prevent the bolt that goes through the broken hole (or the nut) going outwards and it coming undone. Did think about grinding the underside of the broken part at an angle and using a...

    Thanks @Lou C . I still haven't taken pics of the dashboard, which has car like instruments (as opposed to individual gauges mounted separately on say a wooden dash). Did notice today that the voltmeter is all the way over to 18v without a battery connected, is that normal or is the voltmeter...

    When I knew first found out my engine needed a rebuild then read about OMC Cobra parts being difficult to source I thought about the feesibility of converting my setup to a half closed system, that way I could just fit a truck engine and not need to worry about marine cooling system components...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Thanks, I don't know how the dashboard is wired up but it occurred to me that if the ign on wire connects to the ign switch at the front of the boat (as opposed to coming from a relay at the rear), then if the ignition switch gets power from the same wire that runs to the front to power other...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Thanks @Lou C , that helps. Yes it is a Holley 2bbl with electric choke. That explains the AC tap connection (y) I might rebuild the carb but wondering if I should leave it alone until I've at least tested the engine in case I mess up mixture settings during the rebuild. I haven't looked...

    A few pics of old versus new thermostat and the damaged elbow that the thermostat housing sits on. There's a V cut in the old one. Is this damage or is it supposed to be there to allow some bypass? Broken bolt hole on the elbow but I'm hoping there's still plenty material for a nut fitted...
