SD 20 saildrive

[Jacana]

Is there any reason why I need to have a nose cone approx $200 AUD.on my saildrive?
My thoughts are that when motoring,3gm30 yanmah,my speed about 5 knots, instead of a shaped expensive nose cone I could have a couple of large nuts at a tenth of the price.
Cheers
Geoff.

Jacana,
Is it just a nut or a locking device with pin?

[Jacana]

Its the no.5,nose cone nut.

[Jacana]

Just re read your question.Its called a nose cone and it's just a nut and not a locking one with a pin or anything.
Cheers Geoff

NOt sure - but seem to remember when I pulled one off a Bavaria that the treads on the nose cone and the bolt inside it go opposite so they lock each other.......

[Jacana]

The bolt goes inside the spline of the shaft and the cone goes on outside the shaft.So as previously stated ,why not use nuts instead.Yes I would still use the internal locking bolt inside the shaft.

Resubmit for discussion-Any reason why I would need to use a $200 nose cone when a couple of $10 nuts can be screwed on the prop shaft?

My SD20 saildrive came from the factory with out the nose cone- and only a nut with a allen screw in the center- this has worked well since 2006 & 25,000 miles- make ceritin you apply loc tite to the threads or they will fall off at some point !
