It would look like the choice has been made for you!
A four blade brass kort prop that will fit inside the nozzle
already fitted.

If you contact Prop Shop and give them the Kort internal
diameter, hull size and motor, they will advise and supply.

I think this may be the Brocklehust Brocklebank but I think the Kort nozzle is wrong i think it should have a rudder what type or design i don't
know any one out there have a pic of the right rudder for the job.

I am about to put the wooden strip round the bullworks just below deck level, can you advise what type of glue to use or would it have to be something different so there is no reaction with glass-fibre.

I have finished the support for the deck and have fitted the prop shaft and the motor, I have fitted a Mtronik 550 motor but not knowing i think i should of have fitted a 3:1 gearbox or perhaps 5:1 gearbox maybe some of you shipmates can advise.
I will post pic's later today.

the tug is now owned my Liverpool maritime Museum, it might be worth dropping them a line to ask about further information.

Whilst you've got easy access to the hull innards, sand down and smooth of the adhesive/filler while you can. You may also want to think about painting or sealing the GRP too.

Martin,
I;m about to start on a GRP hull myself but I was only going to clean it out a bit and maybe a coat of paint. How, and why, should I seal it on the inside?

Para_Handy
I bought the a kit of a Liverpool tug off ebay that looks exactly like yours and came to the same conclusion as you that it was the Brocklebank. Because it was the closest picture to the kit I could find. It had been fitted with a motor and kort nozzle but no prop. I also found out if it is to be the Brocklebank I need to remove everything and start again. I will be very interested in your build as it is my firrst atempt at building a kit.

 I have taken your advice about fitting a 900 motor with 3000rpm max

I opted for a 75 mm 3 blade propeller and this is also fitted.

I always grind a flat if there's none there.

Don't go too deep as it's not necessary.  ok2
