    2-Stroke Intermittent Bogging During Break-In (25:1 oil mix)

    Check and recheck all the wiring, and connections, including grounds in the Ignition system. Do a Spark test when the engine is hot, to verify that the system can produce a Spark that can jump 3/8" at each Cylinder

    ‘83 Glastron Sx-190 looking for other owners

    I have a Volvo. Somewhere in the 1.5:1 range. It lost a lot of Hole shot when I put the 4bbl and had to jump up in pitch several inches to bring the RPM down to 5000, which was still 200 higher than what Volvo stated for that engine.

    Boat Ramp Etiquette

    Everywhere I have launched, who ever is at the front of the line, onshore, to the ramp goes next, be it launching or loading. I have never seen anyone drag a boat along the dock to be closer to the Ramp. One time, one of the Lake Lice figured he could stand with his PWC in the center of a lane...

    When I had the 4bbl on it it was about 66-67, with the 2bbl it gets a bit over 60

    Boat Ramp Etiquette

    I prefer to have the Boat fully on the trailer before pulling the Trailer out of the water.

    Engine turning over very slowly

    Perhaps, but that isn't the only place a Voltage drop can be caused, weak Battery, bad Cables, loose/dirty Connections, as previously mentioned are also suspects

    2003 8hp Merc...trying to find high altitude jets

    Jets are not an item most dealers keep in stock(unlike spark plugs, they rarely need changing). If available, they can order them

    Boat two stroke engine stalls when throttle is applied unless I throttle up very slowly

    Could also be dirt/gum in the Idle Circuit, you can adjust all day but, only leaner, not richer. Another cause could be a Misadjusted Carb-Spark Sync

    Evinrude year

    That is not what the 77 brochure said. The 25 was the 31.8 cu. in. but the 20 was still a 22 inch block. Probably using up old Inventory. In 78 or 79 they likely went with the bigger block

    Boat Ramp Etiquette

    Dropping a person off and waiting offshore, frees up the dock for those launching/loading solo. Next Trailer in line gets to load. The 'I was first at the dock' crowd must have real problems with those who have one person bringing the trailer from the cottage, and another driving the boat over

    Boat Ramp Etiquette

    Everywhere I have launched, it was the line up to the ramp that determined who loaded/unloaded next.

    1962 Merc 450 restoration ..

    Perhaps putting it in the Oven at 350 for an hour would warm up the Aluminium enough to let the race fall out, plus give you some Baked-on Enamel;)

    Bow rising and taking a long time to come on plane

    Welcome to iboats. Looking at the Video, it does look you the motor is too deep, maybe the bracket is too low and is catching water. Can you put it on a trailer, and take some pictures, at the level of the boat keel, with the engine down so as to show the where the AV Plate is located in...

    Need prop help with new boat

    Well a 5.7 has quite a bit more Torque than a 5 liter. I suspect you need a shorter prop, but before you start swapping props, what Prop is currently on it? What condition is the engine in? Compression Test. Is the spark strong enough at all cylinders to jump a 3/8" gap Is the Timing set...

    Oil on choke?

    Grease perhaps?

    How do you shift gears?? Merc 9.9 Four stroke

    You merely twist the Grip, to move from Gear to Gear. Further movement increases speed. If you are asking how it does this, again the answer is to get the Service manual for that particular Motor. The how's and what's would be in there

    How do you shift gears?? Merc 9.9 Four stroke

    The Shifting is done by twisting the tiller handle? I suspect someone has been tinkering with the Idle Speed and/or Throttle Linkage, and that can lead to it being difficult to shift out of Gear You need the Factory Service Manual to get this system set up and adjusted correctly
