    When you think you sea a dog struggling to swim a few miles out at sea, drive over to rescue it and find it's really a seal. Or you come off waterskis and realise you're surrounded by massive jellyfish.

    No Spark, feels like I’ve tried everything.

    My boat was only getting 9V to the coil on the purple wire and I was getting interference on the VHF. I found a voltage drop across the dead man switch so bridged the dead man switch. This much improved the low voltage issue, it was then getting >11V at the coil with the engine running but...

    Got some dirt in my eye when working under a car. Went in the house to use some Optrex eye wash, found the Optrex cup / goggle thing you fill with Optrex and hold to your eye but couldn't find the bottle of Optrex. My mum was there and helped me find the bottle. I poured some into the cup...

    How much slip does your prop have ?

    All other things being the same (such as boat trim affecting boat drag) it seems to me it comes down to prop thrust versus engine power needed to turn the prop to make that thrust, for a given trim the boat getting more thrust will be going faster. I might expect various prop diameters / pitches...

    How much slip does your prop have ?

    I've been interested in why manufacturers use different gear ratios with different diameter and different pitch props and what the compromises are but it's not something I'm going to be concerned about for my own boat as long as WOT rpm and speed are close to spec. Seems to me prop slip could...

    new engine overheats

    I asked the same in post #25, my dash gauge says the engine runs too cool but I don't fully trust the gauge so will be installing a completely independent 2nd gauge. Don't want to take the thread off track but I'm wondering how/where to fit the sender for the 2nd gauge, I already have a sender...

    new engine overheats

    Is the temp gauge working properly? I seem to have been having the opposite problem (over-cooling) but I am adding a 2nd temp sensor to my carb'd SBF intake manifold to feed a cheap Runleader combined tacho / temp gauge unit to verify the dash temp gauge is reading correctly. I think the dash...

    Birds in the boat . . .

    That's a great idea, don't know why I didn't think of it. Lots of pigeons around here, I don't usually mind them but they keep fouling the boat in the yard, been thinking about shooting some of them.

    Best years for 70-75hp Johnson/Evinrude outboards

    I'm no outboard expert but remember my dad buying a new Sims Super V 14ft boat and new Evinrude 2 cylinder 60hp for it in around 1984. He sold that boat and engine a few years later and bought a used Microplus boat and used 3 cylinder Johnson/Evinrude (I forget which but believe the Johnsons and...

    New seals for fuel filler

    I'd like to replace the seals on my boat's fuel filler. It is a 1996 Four Winns Sundowner 205, there's a long thread about my boat and the Ford 302 engine (that I rebuilt last year)https://forums.iboats.com/threads/1996-four-winns-sundowner-with-5-0-cobra-engine-and-drive.766501/ , so far I've...

    Anyone have experience with exterminating Rats?

    When we were kids there was a local disused limestone quarry that was being used as a landfill rubbish tip site, a short walk from that there was a sewage processing plant and various walking trails around the area, a small river, an old apple orchard, stretch of old disused railway line...

    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...
