Just learnt this the hard way. Ruined a days sibbing. Cord looked fine to. Doh.... spare cord would have been useful

No it's not. If you clean plugs with a brass wire brush they'll never work again. They'll get a nice brass colour coating all over the electrode.

must admit not used a brush on plugs since seagull days other than threads, if motor ok no need these days, maybe a squirt of brake cleaner & annual change, cheap as chips on ebay for most but alas not for twatsoo tldi

DONT!! grease the splines on your driveshaft. If you do you can put extra load on the bearings on your engine which will result in premature wear, light oil will be fine. Also be aware that wd40 is a degreasent and will infact cause rust. I have found white spray grease very good, inexpensive and designed for marine applications

Clymer suggest a light coating of marine grease for this application. Use too much and you'll "suction lock" the shaft in place.

Who told you that lot? Your DRIVESHAFT (not propshaft) will still need greasing on reassembly, but it needs a very light smear. Way Too much grease may cause a the joint to have hydraulic pressure buildup in it which could cause bearing damage, but using a light oil is asking for trouble.

Not greasing propshaft splines is asking for a prop to seize onto the shaft.

WD40 is a lubricant in a carrier fluid,and it can be used to clean grease off but it's not suitable for use as a lubricant except for freeing things off (and there's better options available like PlusGas). It's not suitable for use spraying up under the cowl to protect anything as the lubricant film it leaves is too thin and dries out. Corrosionguard or the equivalent is the best option for that.

Any good waterproof grease will do the job. However, I've been using Corrosion Block grease for the last 5 years as it doesn't seem to harden and clog up steering etc, and does what it says on the tin.

That too I've seen a driveshaft refuse to go back in from a hydraulic lock as well.

Henry,

Is that a brand new Tohatsu 25 HP ? We sell & service 2 strokes 25/30 Tohatsu horses, have lots of good tips for preventive, corrective maintenances.

Happy Boating

I've never had a crank bearing go from greasing the spline

No, I haven't heard that one either. I'd have thought light oil was a waste of time which would be removed after the first dunk. I've 'greased my splines' for as long as I can remember. Prop always comes off, and never had a crank bearing failure.

Greasing the splines is ok ,
though i can see your point if you was to put a blob of really heavy thick grease ontop of the shaft & splines then shove it in it could cause a Hydraulic lock making
the drive shaft not go home proper ,
suppose then it then could put pressure on the bearings when you nip up the bolts on the leg ,

(( first day at work send the young apprentice around asking if anyone has a key for a hydraulic lock )

Some splined shafts have a small concave dimple on top that helps .

Id rather put a light coating of grease on the splines than try get it off when its rusted stuck .

This grease situation on the spline causing bearing failure is a load of bull. I'm sure Clyde outboards will back me up being in the trade
