    Fuel mix in Johnson JH 19A? 1:50 or 1:24

    The label says 1/3 pint which is 24:1 Model # says 1964 In 1964 Johnson saya all engines use 50:1, no mention of Johnson oil(didn't exist yet), just "a reputable outboard motor oil or a regular SAE 30 grade automotive engine oil" Maybe this is a pre 1964 motor, or cowl, sitting on a 1964 stern...

    Potential of wake surfing behind an I/O with prop guard? (as of 2018)

    You mean this drive It would make a great trencher, as when it is fully tillted up, it needs deeper water than when it is fully down> This one unit you can rarely bring to shore. A real pain to trailer too

    General prop question

    There are plenty of differences between various props, brands, and models. To a lot of people, a prop is a prop, they all look the same. Well they are not. BRP makes some really good props, and so does Mercury. They, in my opinion, actually make the best props for recreational boating...

    My favorite little bowrider was a 78-79 Crestliner 550, with a prop rated 90 they could hit about 40 - 42 mph

    1981 Johnson 25hp prop help

    I have never heard of a 14" pitch prop for that engine. The engine was shipped with an 11" from the factory, the range offered by OMC for that engine stopped at 12" We had a 79 25hp on a 14 ft hull and we used the 11"

    Performance data 1990 wellcraft eclipse 196

    "and then had the bright idea that it needed extra cup or pitch. It looks like someone beat on it without pitch blocks and used an adjustable wrench and a steel hammer to work on it. The most high tech, sophisticated prop in the mercury catalog and you let a second rate hack beat on it. " Well...

    Tilt Trim not working 1975 Evinrude 115

    The old tilt system has 2 cylinders between the brackets, only one is a lift cylinder, the other is a shock absorber. I had posted this earlier but deleted it when you said the cylinders were external. The lowering of the engine when you apply throttle is normal, it is not designed to hold the...

    1973 Evinrude 85hp 85393M No Cranking

    Well, it points to the Cables(Positive and Negative) from the Battery and/or the cable between the Solenoid and the Starter motor, or the wire from the switch that energizes the Solenoid. Getting power to the Choke Solenoid is not getting power to the Starter Solenoid. I think that engine still...

    Enertia prop questions

    The crowds weren't too bad off shore this year. Once we got the demo/free boat ride boats trailered, the dock was free to use again. They had a better stage location than they did 2 yrs ago It was sad that a Woman was killed by a train while walking on the Trestle by Moonlight Bay after the...

    Pressurized gas tank

    I tried posting this earlier, but... Blasted iphone This is the oldest tank I could find, but your tank looks even older I would suspect a tear/hole in the diaphragm. It doesn't look like there is any o-ring or seal on the shaft

    What to know about a 2006 Glastron SX 175

    Volvo specs the use of Synthetics for engine and gear oils. Pay particular attention to what gear oil you use, Synthetic marine G5 is the spec. I have used Royal Purple in the engine for the past decade, I will be returning to Volvo's 10 - 40 this fall. I've always used Volvo gear oil. I had a...

    Oil mix adjust screw

    That looks like the Primary Pickup adjustment screw, adjusts the sync between the ignition timing and the point of where the carbs are about to begin opening. The actual idle speed adjustment on that engine is on the side(red arrow) and to adjust it requires the throttle cable be out of the...

    Glastron vs. Maxum opinions

    Looks like my 2002 SX 195, except the colour. The carpets were snap-in. Great for cleaning/drying. as you could hang them up. No carpet in the ski locker, which is good. A bit noisier but no mold factory either.

    evinrude 90hp v4 trailering bracket

    On your engine the trailer lock(red arrow) is what that generation had. Later looper engines had a different system. As I said when you engage the trailer lock, retract the trim rams(orange arrow) until both are all the way in, that will lock the engine down. If you leave it like they are shown...

    1987 17ft invader bow rider

    I will assume this is the hull you are referring to? A deep vee. I've seen the outboard version of it I will guess the hull and engine weigh about 1900 lbs, the fuel and battery other junk another 300 lbs. probably came on a 2300 lb capacity trailer which would weigh about 450-500 lbs. That...

    Prop recommendation to correct tendency to cavitate

    There is another thing to consider regarding costs, an AL prop will bend, chip, break far easier, and may spare the rest of the drivetrain damage. A Stainless, being much stronger will not yield as easily, and will keep banging/hammering until it shapes into a ball. Bent prop shafts are common...

    Prop recommendation to correct tendency to cavitate

    The Enertia is not cheap, Mercury just raised the Wholesale and MSRP in Canada recently. But, it is a very good prop, and well worth the money. Porsh**** claims the Q3 is the same prop. Well when I looked at the two of them, I saw subtle differences between them. How much difference that will...

    Dilemma: Waterskiing - Sea Doo vs small outboard boat (15 ft Glastron)

    Here's a couple of pics of a Vanguard Banshee(a flip/copy of the GT150 pulling up a skier, this boat had a 115 on it. I was back on shore about 600ft. There is 75ft between the skier and the boat This boat was just a few inches longer than the GT150 but for a 15 1/2 footer was a good little...

    Dilemma: Waterskiing - Sea Doo vs small outboard boat (15 ft Glastron)

    This is what I learned to Water Ski behind, did 3 deep water Slalom starts behind it in 1974, I weighed about 165lb. 58 Skagit with a 63 40 Johnson Brochure says the boat weighed 335 lbs. I don't think so
