    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...

    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?

    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...

    Chamfering cylinder ports

    After honing a cylinder block the Evinrude service manual tells you to chamfer the cylinder block with a ball or other suitable hone. Can I use a ball hone and run it from the outside in, spin a little and call it good? How much is enough?
