Aluminium Propellers

These are the most common propellers in use and are found on outboard engines and stern drives. Aluminium propellers can be effectively repaired even after severe damage Castle Marine can repair the blades, replace the diffuser rings, replace the exhaust sealing rings, and replace slipping hubs and re-pitch by up to 2" up or down.

Bronze Propellers  

Bronze propellers are used mainly on competition ski boats, sail boats, commercial fishing boats etc. Blades can be repaired, re-cupped, and re-pitch by up to 2" up or down. On high performance boats the accuracy and consistency of configuration of the propeller is as important as the balance in preventing      vibration and at Castle Marine we pay great attention to these details as well as balancing to an accuracy beyond that required by the manufacturers.

Stainless Steel Propellers

Used on outboards, stern drives, and ski boats they give several advantages. They are more durable, give better fuel economy, and increase speed by about 2 - 3 mph.
At Castle Marine we can repair blades even with extensive damage, replace slipping bushes, balance to a very high standard of accuracy, re-pitch by up to 1" up or down and offer a choice of finishes.

Jet Drive Impellers 

Castle Marine repair Jet Drive Impellers of all types whether they are from Personal Watercraft or Large Commercial up to 800mm diameter. We can repair damaged blades, correct worn diameters, and correct and change the pitch.

Duo Props.

Duo Props. can be repaired and re-bushed. We normally request that both props. of the set are sent for repair in order to ensure that both props in the set are correctly configured. When one prop. in a set is visibly damaged it is quite possible that the mating prop. is also damaged to a lesser extent which will effect performance and fuel consumption. Duo props must run in harmony with each other.

We can replace slipping and damaged hubs in most makes of propeller including Stern Drive, Volvo Duo inc. F series, Volvo Glue in type, and all makes of outboard and outdrive . We carry comprehensive stocks of all the available hubs. Re-hubbing is normally a 1-2 day turn around.
