Memory says 1 - 1.5 x the diameter of the shaft. However that may be wrong

3 inches does seem too long. It would probably be ok but an increased risk of bending the shaft if you pick up a lump of wood.
I'd rather see about an inch unless there is a cone clutch gearbox in which case fore and aft movement of the shaft itself is required.

stick a rope cutter on to fill the gap I put a rope cutter on mine when I replaced the prop shaft and Iβve never regretted it. But then I have no weed hatch.

The other issue is how far from the front of the rudder is it? If too close you will get a lot of tiller judder. I would say 2β back from the bearing, provided that leaves at least 2β between prop and rudder.

However that may be wrong 1.5 x diameter is Spot onπ The universally accepted length for unsupported work in a lathe Chuck tooπ stick a rope cutter on to fill the gap A rope cutter is worth fitting to any shaft - one of the best things Iβve fitted over the years. www.prop-protector.co.uk/deals with weed well, even that bloody nuisance hairweed that grows like mad on the Middle Levels during a good summer π

The only weed hatch I would consider if I ever looked at a new build would be one which came up to deck level.
Slightly unusual for a toy trawler Dulcinea has weed hatches above both props.
The difference is that the deck is above waterline so it is impossible to flood the boat unless the walls of the thing rust out.
Yes you can't reach it with your hands but you can easily arrange a tool to get most stuff off the prop while remaining socially distant from the water, which is always sensible anyway.
I think there were one or two narrow boat builders who did a full depth weed hatch but most of them seem to have gone for the ones where if the seal fails or you don't put it back in properly the boat fills with water...

Mine is deck level, in fact I have boated for a week without the lower plate in position as the lock down failed, it was just a bit slooshy.

Yes I remembered someone mentioning it but was not sure who it was.
Who was the boat builder? I seem to recall your narrow boat had low gunnels.
ETA possibly a Peter Nicholls boat.

If you mean me then Steelwork by Malcolm Pearson one of the last boats he built, Fitout by Phoenix Narrowboats from Coventry done outside the night club in the basin. There are stories about that but not in public

I was thinking of nb idleness previously moored above Bourne end locks. That was mine but the weed hatch access meant crawling under the stern deck and when you are my size that's not fun. Only had to do it a few times in the nine years I owned it as the big prop and JP3 just chewed most things to pulp.
