The Rubex 4 14" × 21" is a 4-blade right-hand aluminium propeller for Solas Rubex engines (4 3/4" gearcase, set by rubex hub kit), Solas part 9513-140-21. For this engine we list 3 pitches from 17" to 21". 21" is the highest pitch in the range – maximum top speed for light, fast hulls running lightly loaded.
Key Features
- ✔ Rubex interchangeable hub system – one propeller, many engines
- ✔ Hub kit absorbs impact and protects the gearcase
- ✔ Thru-hub exhaust for optimal flow
- ✔ 4-blade aluminium design

Is 21" the Right Pitch for Your Boat?
A 21" pitch means this propeller would, in theory, move the boat 21" forward for every full turn. The right pitch lets your Solas Rubex reach the full-throttle RPM range given in its owner's manual with a normal load on board.
- ✔ Engine over-revs at full throttle? Go up in pitch.
- ✔ Engine can't reach its rated RPM, or the boat is slow to plane? Go down in pitch – the next size down for this engine is 19".
- ✔ Rule of thumb: a change of 1" in pitch moves full-throttle engine speed by roughly 150–200 RPM.
Other pitches for your Solas Rubex:
- 17" pitch (14.5" diameter) – the lowest pitch in the range – maximum thrust for heavily loaded boats, pontoons, workboats or towing.
- 19" pitch (14.3" diameter) – a mid-range pitch – balanced all-round performance and the usual starting point; roughly 300–400 RPM more at full throttle than 21".

Questions & Answers
Will this propeller fit my Solas Rubex?
It fits Solas Rubex engines with a 4 3/4" gearcase, set by rubex hub kit. Check the fitment table above and compare the size stamped on your current propeller (14" × 21") before ordering.
Should I choose 21" or a different pitch?
Keep the same pitch as your current propeller if the engine reaches its rated full-throttle RPM. If it struggles to reach rated RPM, 19" is the next step down.
Is this a genuine original part?
This is a genuine Solas propeller – a premium aftermarket replacement made to meet or exceed original equipment (OE) fitment and performance.
How do I know if it is compatible?
Check the Solas part number (9513-140-21) or OEM number on your current propeller, plus your gearcase size and spline count. If you are unsure, send us your engine make, model and year and we will confirm fitment before you order.
Does this propeller require a separate hub kit?
Yes. Rubex propellers use an interchangeable hub. The correct Solas Rubex hub kit for your engine is required and is not included.
Note: Please verify your engine's gearcase size, spline count and propeller size against the references above before purchasing. Domain: 4boats.co.uk
