    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Thanks for all replies. The marina did email me back, they said they couldn't be sure from my pics but thought my drive looked like a late Cobra drive... But last year I was convinced it was a Volvo SX spec drive and I seem to remember further back on this thread other people telling me it...

    Prop Selection - Bayliner 175

    Is prop slip similar to torque convertor slip and stall speed? Hypothetical boat tied to a dock so it can't move, the faster the prop spins the more slip but also tries to push the boat with more force. There is obviously some slip relative to boat speed or the boat would need a clutch or...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    I think I found out why the drain plug and seals I bought didn't fit, I bought the wrong parts, bought to fit an OMC drive not a Volvo SX drive. I found this out today when I phoned a marina, they told me to email a pic of my drive and they'd advise which plugs and seals to buy. I found an...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Starting to think about what I still need to do to the boat before the start of the season... Need to change the drive oil but also want to replace the bottom drain plug, top dipstick plug, I forget if there's also a middle level plug(?). It is a 1995/6 OMC Cobra setup with Ford engine and...

    Prop Selection - Bayliner 175

    I agree with Jlh3rd that compression test should really be done with the plugs out and open throttle but that is more likely to increase the pressure reading than anything else - Other plugs removed so other cylinders don't have compression so the starter will crank the engine faster leading to...

    Prop Selection - Bayliner 175

    A dynamic compression test will usually read higher than static compression because the compression heats up the air in the cylinder. If you could turn the engine slowly enough to allow the heat of compression to dissipate a 10:1 engine would read max 150psi and probably lower if the inlet...

    Listing to port side

    Seems a few people know this type of boat with unusual hull cutout section are/were built (trout fishing boats?). Some have said designed for engines between 9.9 and 40hp. I wonder if this particular boat was designed for an engine toward the lower end of that 9.9>40hp rating scale and if...

    Four Wins Volvo Penta stiff steering

    Watching this thread because my 1995 Four Winns with Volvo/OMC Cobra/Ford 5.0 has play in the steering and this is a similar subject. It isn't stiff to turn but if I steer one way I have to turn it some distance the other way before it steers the drive moves the other way, I don't know if this...

    Attempting a motor rebuild

    If honing or boring a 2 stroke block do the ports need any further work to prevent damaging the rings? I don't know if 2 stroke ports can be sharp edged like they'd be after a bore / hone or need to have a tapered edge.

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Been months since my last post, not much boating going on in England in January! I've been doing a it of work on the boat on and off. The cabin furnishings were all dirty with the overhead carpeting / rat fur water stained in places. The carpet in the open rear was dirty. I bought a small...

    2002 5,7 Mercruiser exhaust manifold keeps cracking - 5 times this summer

    Been a few months since I last visited this forum, not much boating at this time of year here in England lol. I wonder if - While the engine(s) under load the marine manifold gets warm/hot, perhaps not even excessively hot, maybe no hot patches. But then if you come off the throttle suddenly...

    2002 5,7 Mercruiser exhaust manifold keeps cracking - 5 times this summer

    It's not an engine that's broken though, just the marine exhaust manifolds that keep cracking?

    Does the antifreeze you use really matter?

    I did mean using neat automotive antifreeze, though maybe not being able to remove all the water (particularly from the engine) so there might still be a mix. But, yes, my question was about if I did get all water out would neat antifreeze be a problem. Now you've said neat antifreeze could be a...

    Does the antifreeze you use really matter?

    I didn't think about the trailer springs lol! I've only used my trailer in fresh river water, is this something I should be concerned about?

    Does the antifreeze you use really matter?

    I'm a little late to reply and the thread has moved on, I agree with you, but I was talking draining most of the water from my block, manifolds, PAS cooler and raw water pump and pouring in neat antifreeze. You did answer my question about whether neat antifreeze could damage anything such as my...
