    Just thought I'd share a nice photo.

    That Merc was pre 1965, so it was in a Different Century, the 20th Century. We are now in the 21st Century

    Need help with steering cable.

    That looks like an old Teleflex Steering Cable. I know that these Days other Brands use that same Design, but in the 70s

    Just thought I'd share a nice photo.

    I was told that there were Water Skis and an Outboard Motor in this Picture, but be damned if I can see either

    1976 Evinrude 9.9

    I would take the Pump apart again, and reassemble it making sure all the Parts are undamaged and are positioned correctly. Sanding any Gasket Mating Surface where Raised Areas are involved, can result in creating Leaks. Without actually having the Pump in my Hands, it is not easiest thing to...

    Sputtering Johnson V4 90hp - 1994

    Looking at it again, maybe it looks like a Decanter for Wine...

    Should I change prop pitch/ go to stainless.

    Depends what you think is 'Improved Performance'. My first experience with a SS was in 1985, when I replaced the Al Prop on my I6 115. Both Mercury Props, no increase in Top Speed, but a much better Grip on the Water, it not longer lost its Bite in turns when trimmed out, and could lift the Bow...

    1976 Evinrude 9.9

    Here is one of the Videos on YouTube showing a Pump like yours, maybe you've seen it, but it does point out a couple of tricky spots that could cause problems

    Should I change prop pitch/ go to stainless.

    ROTFLMAO!!! My experience with Rocks and SS Props. Bent the Propshaft too. Impact occurred at about 21mph

    Should I change prop pitch/ go to stainless.

    The pic of 15" shows it to be a Stainless. As for the 17" being Standard. It is the Pitch that is shipped with the Engine. It was picked by the Manufacturer, as being suitable for the expected Boats the Engine most likely to be installed on. In the Evinrude-Johnson Engine Brochures, it was...

    Water Pressure gauge installation, need a little help!

    I suspect the Instructions are referring to a Mercury, as they almost always had a Place, with a Brass Plug where a Pressure Gauge Hose/Tube could be fitted

    Dumb question

    It probably had a Pinch Band type Clamp on it from the Factory. I'm surprised the Hose hasn't popped off.

    HELP - Mercury Motor Won’t Start - Carburetor is suspect

    Welcome to iboats How did you come to the Conclusion that this is Mercury? It is an OMC Motor(Evinrude/Johnson) What are the Compression Numbers? Is the Spark strong enough to jump a 3/8" Gap? Is there any Blockage in the Fuel System? Carb Circuits could be gummed up with Dirt, Gum, and...

    115 6c TOP piston cylinder issue

    Even though, in theory the Rings should fit, the Piston Rings Gaps should be checked and Adjusted to each and every Cylinder Bore. A lot of Machine Shops will require the Intended Pistons be supplied to them with the Block, so they can be measured(even brand new Parts can vary slightly in size)...

    Should I change prop pitch/ go to stainless.

    It is your Motor and you are free to downgrade your Boat's Performance with that stuff.

    Sputtering Johnson V4 90hp - 1994

    You said in the Original Post that your last Experience was with SBC. Forget most of what you know about the Chevy, in fact any Car/Truck Engine, as these 2 Strokes are quite different, when it comes to Adjusting. First Things first, have you done a Compression Test? If No, do one and post the...

    Should I change prop pitch/ go to stainless.

    That big white piece of Garbage bolted to the AV Plate is Not Standard on any OMC Motor. Whatever that thing bolted to the Skeg is, is certainly going to slow you Down, I suspect the 15" is gonna be close to what you need to run. WOT Range for your Motor is 4500 - 5500. That Motor is making...

    115 6c TOP piston cylinder issue

    600-650rpm, in Forward was the Idle Speed Spec for those engines. I used to adjust them for 575-625, just to lower the Shock imposed on the Driveline when put into Gear. Regarding your Piston Rings. You are checking their End Gaps in their assigned Cylinder at several spots, and adjusting if...

    Sputtering Johnson V4 90hp - 1994

    If you are referring to the Milk Bottle shaped Opening not being covered by the Gasket, it would be a Waste of Paper, as there is nothing on the Manifold to contact
