    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    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...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    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...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    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...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    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...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Thanks @alldodge and @Lou C A few pics of my new alternator including a pic of new and old alternators side by side, the new one looks like the one bottom right in the pic above, seems to fit but I won't know for sure until I start to put it all back together. A couple of pics of...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Thanks. I didn't use a torque wrench but it felt like I tightened the coupler / flywheel nuts to around 45ft/lbs. I haven't had time to do much with the boat since my last post. Around the time of my last post the weather was really changeable, I was getting fed up of starting some work on the...

    I don't want to take this thread off topic but are marine exhaust manifolds available for LS motors? I'm British and convert vehicles to run on LPG (propane) for a living. A scaffold cradle firm I recently did some work for run a fleet of small flat back trucks. The trucks are only available...

    Volvo Penta SX-M Trim drifting down.

    @Bondo and @Scott Danforth recently helped answer my questions about my Volvo drive dropping. I may have been lucky because I found a weep where a line connects to the pump, fixed the leak (new Oring), filled with new fluid, bled the system and so far it hasn't fallen again. I haven't tried it...

    I just checked the raw water pump, removed the 3 bolts to check the impellor etc. It seems in good condition and it turned easier with the rear cover removed so it seems the bearings are OK. Put it back together without damaging the gasket.

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Thanks. I can understand the drain but not why it needs a length of pipe/hose attached to it... it would drain into the bilge without the pipe and the pipe needs to run to lower than the bellhousing or the drain won't work, the only place lower than the bellhousing is the bilge.
