    Gearcase oil change

    Hello, The gearcase oil was changed on my 1988 Evinrude 9.9 3 years ago. It has run about 10 hours since. The oil is up to the top plug and a sample from the bottom one was clear golden colour. No water. Does it need changing, please?

    Evinrude 9.9 over heating

    Hello, This is a new slant on a problem I have had some time with my 1988 Evinrude 9.9. The cylinder head and thermostat housing show few signs of sediment building up. I tried running the engine briefly in a tank with the thermostat cover off. There has been no thermostat fitted for some time...

    Flushing Evinrude 9.9

    Thanks guys, for all the input. I don't have a flushing port, so guess I will have to get the bucket out again. And hand out earplugs and/or beer!

    Flushing Evinrude 9.9

    Thanks guys. I will give up on the idea of flushing thru the thermostat housing, and running on muffs makes too much noise in the marina. Being on a tender its used very little and I do flush in a bucket before the winter. I think the grommet may be damaged because I hear they can be fitted...

    Thank you for your replies. The motor is on a tender and has to be flushed at the end of the day in port when its back sitting on the swim platform. Its not practical to run it in a bucket. There is no thermostat, but the motor runs at a reasonable temperature. The water passages seem...

    Flushing Evinrude 9.9

    Hello. It would seem an easy job to fit a hose connection to the thermostat housing on a 1988 Evinrude 9.9. Would it work as a fresh water flush without running the engine, please?

    I have a 1989 Evinrude 9.9 with 15hp carburetter on a 9 ft. speedboat used in salt water. In the last 4 years it has always been flushed out with fresh water at the end of the season.

    Hello, I have a 1989 Evinrude 9.9 hp, recently fitted with a 15hp carburetter. I do not know the history of the engine, but it seems to run well enough although rather smoky on 50:1. I have had previous experiences of other makes of two strokes where they seem to be running OK and will...

    Hello. When my outboard is taken out of the water it has to be stowed on board. Clearly, if it is stowed horizontally as normal, i.e. the prop facing upward and below the level of the power head, any water left in the cooling system will not get inside the combustion chambers or cylinders. I...

    It was the washer (or rather, the lack of it!). The boat will now do over 20 knots solo, although will not get on the plane with two people. Very many thanks to all of you who took so much trouble to comment on the situation. If there is anybody out there who is not completely bored with my...
