Where did you do the damage?? Was it in a wave trough at the enterance to the run?

I had concerns about this on the way in, but managed to surf a wave virtually all the way to the quay! More than 8knts SOG, but only 4kts on the paddle wheel ...

Steve

PS there were some very good recommendations for ali prop repairs of few days back

That's a pretty good illustration of why I'm not a great fan of standard ally Yamaha props-they seem to lose large chunks like yours did rather than bend.

It's a shame there isn't an easily available off the shelf alternative in the UK.

Yep -took the big boat in & out fine , then tried the little one & this . Never mind - I have spare & within 5 mins its good as new. No sign of any damage to anything else - as has been said good reason not to stainless .........

There were some big swells / breaking waves in the the run & I was more concerned about getting caught up by one that really looking at how close to the middle of the channel I was ( i think its abit off at the outer end anyway judging by the break ) .

Was hoping for a little sun tonight to go to yarmouth for a drink / dinner - maybe another day unless it clears in the next hour.

If I venture into area's of known shallowness I always trim the engine up as much as possible without losing thrust and steerage.

Indeed a good idea , but in & out of Christchurch in the weather we have had, and in the narrow channel its always a bit of gamble in keeping the control without risking the prop........

I have a couple of bent alloy props and am quite happy to keep alloy for the same reason though I do seem to have stopped rotavating the beach in the last year or so, the prop I have does have some chunks out of it but that was something I hit in the water, never did find out what it was but it wasn't attached to the bottom.

Know how you feel: I hit something coming back in off the SF Bay last New Years; snapped the fish finder transducer clean off (it was on a kick-up mount, but apparently wanted to kick up higher than the mount would allow.) No prop damage, though; suspect it was a piece of lumber or similar.

So, $50 or so for a new transducer, and probably an hour and a half pulling the damn thing in... (Have the old one wired and glued together for the moment; seems to be holding up OK.)

Can't you set an offset into your sounder so you get the depth below the skeg?
