When I put mine in I used some silicon grease (like red jam) and then slowly pulled it in with a long bolt / nut with some large washers. Originally I'd tried knocking it in but fudged one seal up so asked the spanner monkey how he did it at the shop....

ben350; thanks alot for the tip! Have ordered the parts at my local Yamaha store, so Ill guess this will be a job for next weekend Dont have any silicon grease, but Ill guess Ill find a replacement. Dont understand exactly how you used the bolt / nut / washers, but Ill guess I understand when I am at the job. Thanks again
I used 1 large bolt and 2 large washers along with 2 dished washers that sat nicely into each side of the seal, put a nut onto the end and gradually tightened up the nut until it had slowly pulled the seal down into its housing in the casing.
Thanks for the tip, Ben And now I see why I need to dismantle the whole engine cover - the water pump axle is actually situated in the cover itself. The old sealing was pretty stuck, corroded, and absolutely weared out. Some force had to be used. The groove for the sealing where a little corroded, so I polished it with some crome polish until it was smooth and shiny. The shaft on the propeller where not nice at all, so it will be exciting to see how long time before it starts leaking I used some pot scrub to polish away the worst on the axle, so it hopefully will stay OK for some time. On the sealing I used some engine oil, and like you said Ben, a bolt and some large washers. The new one slipped in smooth as %¤# virgin. Tight'n'nice SInce the engine cover was quite dirty, I also dismantled the oil pump so I could wash the covers in the dishwasher (I have one dishwasher only for purpose like this, dont ever use your ordinary dishwasher, as it will be greasy inside forever). SO, now out to the garage to get all parts together and fill her up with oil and water, and cross fingers
Well, I had to be home from work today, my 3 year old bloke is a bit sick. So, I got a few hours for myself, mounting the rest of the stuff around the engine, mount/adjust/lubricate the powervalve system, oil pump line/bleeding, lubricating all wires, dismantling/cleaning of emergency cut-off button, etc, and finally fired up. Pretty hard to start, but this is a behaviour of this bastard, never found any obvious fault. As soon as it starts, it runs OK. The workshop manual says I should force maximum throttle of the oil pump a few minutes, just to be sure its lubricating good enough, and I belive it did: After half a minute my garage was stuffed with smoke ) So far, after 15 minutes running in the garage, it looks good. It runs OK, no water in oil, no oil in water.. Before I changed sealing the oil became yellow/brown after only a few minutes, so something positive has happened... I'm pretty sure the shaft will wreck the sealing sooner or later, preferably later. And Ben, you're my star! I hope I can have your offer as a credit Ill see how long it is working OK, and if/when I get trouble, I can ask you if you still have it. Ill of course pay a reasonable price for it ;)
