Thanks for the responses guys.
The background is that I got a good deal on a new ski due to the fact that it had some limited damage to the hull which I got fixed by distributor prior to delivery. Hence I feel obliged to give them chance to rectify the situation, without hanging them out to dry (pardon the pun)
I was disappointed with the very leaky bailers (drain tubes) as this was unexpected. Needed help to carry ski out the water after first 30min paddle due to water in hull! It's a long drive to supplier so fixed these myself with epoxy under direction from manufacturer. Also wanted to know myself that it was done thoroughly.
Suspected the rudder post after reading very useful Huki article ( [url=

Thanks for support guys.
