    1988 Mercury 115

    Another mix of parts. Yes cowl is in the 1980 - 1983 range, the power trim is Post 1983. Does the serial number on the bracket match the one on the block? Oil injection didn't appear on the inline six until 1986. Do your own compression test. Check the gear oil for water. Look around the...

    Any reason why I shouldn't use this lower unit oil?

    Actually they don't. They may have spiral gears but not Hypoid.

    Any reason why I shouldn't use this lower unit oil?

    In the 1960s OMC only marked one oil, so the direction from OMC was Type C. In a 1958 35 hp owners manual is says Hypoid 90 oil , and a 1957 35 hp owners manual says a quality automotive 90 weight hypoid oil, and in an Emergency 30 weight motor could be used. I always wondered what constituted...

    Any reason why I shouldn't use this lower unit oil?

    Here are the lubrication pages from a 1965 90hp Evinrude owners manual. This is of course an 'Electric Shift' motor. Nowhere in the manual does it mention optional oils. I don't think the laws about the "no cast oil" were in effect at the time this engine. Unfortunately I don't have any...

    Weird LT1 problem

    Usually this engine runs very smooth, starts within 2 seconds unless it is colder than -18, then it takes about 4 seconds. But... Some days on first start, engine occasionally would seem like it had flooded, like a stuck injector had drain the fuel line overnight. Holding the pedal to the floor...

    '87 Mercury 115hp IL6 Couple of issues.

    Here's a pic I took 30 yrs ago changing the cover on a 1984 115hp. As for the sensor, that's the first time I've ever seen anything screwed in there. Though it isn't really seen in the first image, the front support is also removed to enable the lower cowl to be tilted out of the way Pic gets...

    1999 FICHT 150 " I know now guys"

    I had a 1998 150 Ficht. The first couple of 'updates' were reprograming of the Engine MAP software and different sparkplugs. That was either 1998 or 1999. Both times it resulted in slightly slower acceleration, and slightly lower top speed. Indexing of the spark plugs was another one of the...

    What happened to Johnson and Evinrude?

    I had a 98 150 Ficht, it never gave me trouble, but I always had the updates done. Several Prom updates, new cylinder heads, and eventually a newer style powerhead. The new powerhead had about 50hrs on it when I traded it in. There was already a cylinder with as the mechanic said "a neat little...

    New and in need of some advice: 40HP Johnson Electramatic

    My dad had a 1963 40hp Electramatic from 1972 - 75. Learned to waterski behind that motor, even learned deep water Slalom starts behind it. Had the flywheel come loose in 74. HOT lamp started coming on in 74, even though the water pump and thermostat were working fine. Never did figure it out...

    Stiff Throttle plates

    Some have a little circular grove machined into the shaft bore and a grove at the bottom of the bore machined from the circular groove to the venture bore. The circular groove interrupts any gasoline seeping along the shaft and the bottom groove returns it to the venturi. Sometimes the shafts...

    New to me ..1956 Evinrude 15 hp Fast Twin... A Little help and information..

    Well the engine has the pressurized fuel connector. The tank is not a pressure tank. You have two options, one is to find a pressure tank, the other, is to add a fuel pump to the engine.
