    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Today I took the road cover back off the boat with intention of doing a compression test, I'd already removed the plugs and had also removed the air filter flame arrestor (just for a better view of the rear of the transom and components mounted on it). We had a rain storm the other day and it...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Thankyou very much @Lou C , @kenny nunez and @Scott Danforth , very much appreciated info! I still have concerns about the height for lifting the engine, I understand I could remove the trailer wheels but that would only give me a extra few inches, I don't know if that would be enough. I'll...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Thanks @Scott Danforth , our last posts crossed. This would be the first time I've removed a drive and I didn't know there were flappers! I could probably muddle through but I'd rather admit I don't know what I'm doing and ask for advice / links on major work like that. I can strip and rebuild...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Thanks, makes sense. If I only swap from the 5.0 to a 5.8 could I keep the same lower and just fit a bigger pitch prop? I'm thinking Lou said the drive can take big block power torque so it should be able to handle a 5.8.. Just hypothetical for now, I'll see what's wrong with this engine...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    That's more good news regards the drive @Lou C , thanks again. I did think it possible to be able to fix a valve train related problem with the engine still in the boat, have to remove the engine to fix a bottom end problem. I don't have a stethoscope but I'm often listening around engines...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    @Lou C , Thanks, that's reassuring and seems good news. It probably also explains why prop vendors are telling me props for the SX drive are compatible. So does my drive have the cone clutch or dog clutch? My dad bought a Winner Viscount (cuddy boat made in Wales) in the 80's, it had a 3L...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Just to clarify - which Volvo drive? Will all parts be the same? I'll be getting a new prop. I'll check for a PAS leak but the level in the pump hasn't gone down and there's no mess in the bilge. I have noticed there seems to be some play on the steering wheel, if I turn the wheel one way...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    @kenny nunez , thanks, our posts crossed, I started writing my last post, had my tea (evening meal), finished writing and posted then noticed your post. Yes I intend on doing a compression test and I'll keep in mind what you said about cleaning the pulleys up. I'm expecting to be able to buy...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Is there a website / resource where I can enter my engine/leg code / serial number and find a list of compatible part numbers? The product number and serial number of my Cobra leg are clear (pictured in last post above) but the numbers on the stickers on my engine are faded and more difficult...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Thanks. I wonder if my boat is a '96 model, if the drive unit could have been made before '94? If it was made between 94 and 98 will it really be 'exactly' the same as a Volvo SX leg or are there still minor differences in some of the components? How much torque can the Cobra / SX leg...

    My drive is a Cobra, is that similar to a Volvo SX-M?

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Thanks everyone for all the replies, I think that answers all my questions for now, much appreciated. I have some other work to do over the next few days, when I get around to working on the boat again I'll post updates and probably ask a few more questions then. A few pics... Took the...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Seems that I can fit any 302Windsor in my boat then? Just make sure bracket holes are in the right places? And any 351Windsor will fit? Same concerns about bracket holes and I'd need a suitable intake manifold. I don't know if 351's were always fitted with 4 barrel carbs / manifolds or were...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Thanks Dubs283 and InvaderScott. I realise I'd need a different intake manifold if swapping from the 302 to a 351 but I appreciate all replies and info. I only realised because I read about the different deck heights... If I hadn't read about the different deck heights I might have assumed they...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Thanks. I knew about having to change headgaskets to marine spec but I didn't know about the different cam. The main things I wanted to check were that a different engine would mate up to the marinising bits, which you've answered thanks. Would a 351 also match up with the marinising...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Thanks for the reply and for merging my threads, sorry I thought it would be better to split up the engine and leg issues to different threads but I understand your point. It's a carb engine, Holley 2 barrel. I'm not sure if I could post pictures or if they would help? I find the Volvo Penta /...

    Hello everyone, I'm a new member and this is my first post. I did look to see if there was an introductions thread but didn't find one, hope it's OK to dive in with this post. My username Lpgc is the same username I use on a few other car related forums, I convert vehicles to run on LPG...
