    Water leaking between where jet pump flange bolts on to motor tail shaft.

    When engine is running there is a considerable amount of water spraying from the flange where to the two pieces bolt together. I assume I have a leaking seal but top or bottom of bearing case?

    My 1995 65 HP Jet Evinrude is leaking water out the seam where the lower unit bolts on. Should there be a gasket or sealed up so all the water goes out the nozzle?

    Vintage Motor

    Has anyone heard of a Jason or a Munch small outboard motor? Found a couple in a barn and really can't read the names real well but I think that is what they said. The Munch I think is a 4 stroke.

    Water Logged Foam

    I think the foam under the floor is water logged on my 1995 OMC Roughneck 1768AW. I weighed the boat and trailer the other day and it weighs 2880 lbs. I think that is way to much. Is there anyway to dry it out or do I need to completely remove the aluminum deck and replace the foam? What...

    Low speed missfire on 2003 Merc 115 2 stroke

    Been working on this problem for several months. My motor (1115422AY) seems to have an intermittent miss from idle up to around 2000 rpms. Even had it miss at 5000 rpms occasionally. Seems worse in the mornings when it is cold. Once warmed up it seems better. Pulled the plugs to see which...

    2003 115 Two Stroke Missing at low RPM's

    My motor has started missing at low RPM's recently. I thought fouled plugs and changed them but it didn't completely eliminate the issue. These models are the ones that only use two cylinders under a certain RPM and then kick the other two in when throttling up. It seems once I get the boat...

    1995 v4 crossflow 90/65 Jet Drive Carb for Higher Elevation

    I've been told that for higher elevations there is a different carb set up for these motors. I use my boat around 4350' elevation. Are there different carb jets that can be installed in my existing carb? How do I tell if it needs the different carbs/jets. Doggy performance, higher fuel...

    90 E90JELOR convert to 115 HP

    It is a 90 hp crossflow powerhead. It gets de rated to 65 hp by adding the jet drive. See the 65 hp engine cover. I never thought of the foam saturated. I guess I should weigh the entire set up too. My original question was, can I add the exhaust, carbs for a 115 powerhead on my 90 hp power...

    Checking Timing without Test Wheel

    Id like to check the ignition timing on my 1995 E90JLEOR and the manual says to use a test wheel and not the flushing tool. How can I see if I'm 28deg BTDC at wide open throttle without the test wheel?

    Control Box cable with lot of slack

    How much slack should you see in the control box cable from a 1995 side mount control box? If I have some one hold the main control box lever and I push/pull on the cable where it connects to the throttle I see about an inch of travel without moving the handle. If I go to the other end and...

    How to Verify Cooling Path on 95 90/65 hp v4 Jet

    Guys, before I fire up my rebuild is there a way to verify that I've got water flow through each cylinder? Can I use the flushing port at the bottom of the lower unit, connect garden hose and then remove each hose from the bottom of each head that goes to the thermostat housing? I should see...

    Connecting rod weight

    As I've been told that pistons for a 1995 90HP Evinrude weigh the same can I assume the rods do too? Long story short, can you replace just one?

    Starting/running with out Jet impeller

    I'm getting close to be able to fire my 1995 90/65 Jet Evinrude after a rebuild. Can I fill a tank of water to run it in but remove the Jet Drive impeller to test the engine. The lakes/rivers here in Mt are a little frosty and hard. Just want to make sure it'll fire before driving a fur piece...

Upon further examination of block the circlip on the cylinder above has came out causing 2 grooves in that cylinder deep enough to ruin that cylinder also. Could that circlip get into the cylinder below it through the...
