Cannot really see a problem with blanking off myself.
Many boats like my own have cockpit/deck drains that have to be left open all the time. Their integrity relies on fairly thin braided bendable plastic pipe.
The log impeller and skin fitting is plastic and is a very weak area on a boat.
This may sound nuts but I would be inclined to put a seacock on the fitting plus a blanking nut after the seacock plug for extra safety. Only my opinion of course, but I would prefer it this way than a glass repair.
Nice that this thread proves that we all have our own ideas and priorities concerning safety. Unfortunate that some feel the need to be rather aggressive with their opinions.
Sure you will have a great time with your new purchase.

Thanks for all the advice offered.
Threadlock - does it need to be marine specific? Or will something like this be appropriate:

I have read this thread with interest,
If I might add my two penny worth.
First of all ignore the doom and gloom merchants who start saying that they'd rather not have any underwater fittings at all. The boat might sink, they might fail, don't blame us if you lose everything etc etc. Nearly every boat of any size has some underwater fittings. If they are made of good quality material, mounted correctly on backing pads, maintained well, and checked regularly, you can sleep easy in your bed.
As far as your blanking cap is concerned, Sika flex will be fine. You will struggle to get it off afterwards as it sticks fairly well. If you know want to get it off sometime in the future, try PTFE. Its what's on most of our underwater fittings.
Smart boat-owners have tapered bungs tied next to their skin fittings just in case the things shear off.
Just to tease the doom and gloom brigade - we have 14 (yes fourteen) through-hull fittings on Serendipity. She doesn't leak a drop, and I have total confidence in her.
