Mercury 100hp 4 smoker flushing

[nugent]

first year of ever putting a boat on a mooring, trying to flush out engine with std water muffs.after day out. dodgy mission i can tell thee,
i beleive there is a flush attatchment you can fit or screw in for serving same purpose, but do not need to hang of the back of boat. so much to marry them up.
i have looked every placeon net and can not find one, i beleive they are a 100hp yamaha under mercury badging.. any fellow ribbers out there can advise where to purchase said item or have used one do they wash out the impellor also or just the engine block
ta muchus,,,,

Don't see how you can flush the engine with muffs if its on a morring, as the engine would be trimmed up and not at a good angle for running a four stroke .

There is an adapter which screws into the driveshaft housing cowling where the tell tale comes out (if you look at it there is a thread). I believe it is a similar fitting to the hoselock garden stuff but its a bigger american thread. Should be able to get one from a merc/mariner dealer, or garden machinery centre which does the american made lawn mowers etc. It will flush out the powerhead but not the impeller housing, as you cannot run the engine with this type of adapter. Although a certain amount of water will travel down there.

oops i did run it tilted!!! i have placed one on order, but they reckon it is the same as a hoselock adaptor, can not afford to travel all way down south to find out it isnt, are these then left on the engine, or removed after flushing out?
thanks for reply Tue.

You will have to remove after each time you flush the engine, but its only got to be hand tight and is easily reachable if you tilt the engine .

We flush out the 80 yam tilted, how else can it be done on a mooring?
Wheres the harm in haveing the engine running tilted?
Haveing tried the flushing kit it seemed to do nothing.

i know the flush kit is used with out engine running so does not need tilting

With a sump full of oil and the angle of a fully tilted engine, there is the risk of lack of lubrication as the oil pump cannot draw from the sump correctly. You shouldn't run a fourstroke if its tilted above the shallow water run level.

let me tell you the trick, well on an opti anyway

my normal blue reinforced garden hose fits in the hole behind the threads where that plastic plug fits. be careful not to drop the rubber washer into the water. you can run the engine or not, water runs from the telltale and also out of the leg so it completely flushes the whole engine it would seem.

if your hose doesnt fit in there then let me know and i will cut a length off of mine for you and post it as a swap for a gallon of opti oil!!!

you canthen put a hose adapter to the short blue hose if necessary and hey presto you are done

let me know if that works for you

my yellow hose was too big so some wont fit in there
