    Math problem

    Been said you'd need 15.36oz in a 6 gallon tank, 2.56oz in a 1 gallon tank. So if you already had a gallon of pre-mixed in the tank it will have contained 2.56oz oil. You added 16oz of oil, so now your 1 gallon contains close to 18.6oz. If you add an extra 5 gallons of fuel you'll have 18.6oz...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Yes I'd bet most people on the planet know about Holley carbs lol, I don't know much about specific features though. I was meaning to take another look at the Holley website if/when I got around to rebuilding this carb, I'll look sooner now, thanks.

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Thanks @Horigan, I appreciate you trying to help but as @Lou C says my fuelling setup is the Holley 2bbl. I haven't had the carb apart and I left it in the boat all winter when I had the engine removed. After rebuilding the engine all I did to clean the carb was put some fuel in it and...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Thanks Lou, Yes it is the Prestolite with electronic 'points' (not mechanical points). I haven't lubricated the weights yet, how is that done? It didn't seem like a misfire, seemed more like the mixture gradually got leaner. But when back on the jetty near the slipway I changed the dizzy cap...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Used the boat on the river for another couple of days and a total of around 70 miles again, this time we went further up the river where there are fewer boats and fishermen to moan about breaking the speed limit. Maintained 30mph at around 3000rpm for 20 minutes no problem but when I opened her...

    Process for changing boat trailers?

    Thanks, I have copied and pasted your answer to my friend. Come to think of it I've read similar before. My friend and I didn't know if this would cause a lot of strain on the transom or other parts of the boat. Didn't want to punch a hole through the hull!

    Process for changing boat trailers?

    Slightly off topic but probably not worth starting a new thread about... My friend has a Bayliner bowrider with 4.3 Mercruiser, he wants to lower the rollers on the trailer to make the boat sit lower on the trailer to make it easier to launch. It can all be modified using his existing rollers...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Thanks, I think I understand how the system works but wasn't sure if the water flowed up or down through the wide diameter pipe to the circulation pump. I was thinking was there will always be a lot of water recirculating even when the stat is closed. During time the stat is closed any rust...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Not sure if the boat has been used in salt water, I know the last owner used it only on fresh water and some people have said the drive etc seem in too good condition for it to have been left for long in salt water. So far I've only used it on fresh water but I do plan on using it on salt water...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    I'd forgotten about the pas cooler when I wrote my ideas for winterising, think I would've remembered when the time comes. See what you mean about not needing to remove the stat housing. Does salt away shift rust scale too? Or what product will shift rust scale? The reason why I want to get rid...

    I bought oxalic acid powder to mix with water, obviously to some extent strength depends on weight of powder versus quantity of water. But, like you say, even if I made it as strong as possible it still wouldn't be a very strong acid, after a certain concentration the powder just stops...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    For sure your Jeep is a better tow car than the Elgrand I use. Yes head gaskets, in fact all water gaskets including the water ports on the inlet manifold, various gaskets around the water pump area and the water pump itself are all concerns if using chemicals in the cooling system. I don't...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    I remember you mentioned tapping the stat housing earlier in the thread but I was expecting a problem with the seal around the stat. How long before the rust flakes stop being a problem? I wondered if there was anything I could put in the cooling system to get rid of the rust without damaging...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Did a little on the boat today. Recap - the tacho was reading double actual rpm and the engine was running too cool. Today the gizmo I ordered from Ebay (that I've mentioned earlier on thread) that converts tacho pulses from any engine to suit any tacho arrived and I fitted it. It wires to...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    Thanks Lou. I haven't tested the stat but it is new. I might refit the old stat before further testing. Me and a friend pulled the boat out of the river today but had a little ride of around 8 miles on it first, the gauge on the dash never moved above 120F even when I gave it some stick and...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    I haven't used sealant on the housing to block gasket, just used a bare gasket because it's easier to disassemble while I'm trying to fix the cold running issue but it doesn't leak. I didn't have a spare gasket last time I had it apart so made one from gasket paper, it was an easy gasket to make...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    I put the boat back in the river on Saturday, took my sister for a ride who hasn't been on the river since our mid teens around 40 years ago, she loved it. The boat is still on a mooring on the river. Still haven't done a radio check. Was surprised that with the engine running there's ignition...

    Process for changing boat trailers?

    Stating the obvious, an easy way to swap trailers is have a friend tow the new empty trailer to the water and tow the old trailer back home lol.
