For this engine we list 5 pitches from 15" to 23". 23" is the highest pitch in the range – maximum top speed for light, fast hulls running lightly loaded.
Key Features
- ✔ Pressed-in rubber hub – no hub kit needed
- ✔ Thru-hub exhaust for optimal flow
- ✔ 3-blade aluminium design
- ✔ Anti-corrosion paint finish

Is 23" the Right Pitch for Your Boat?
A 23" pitch means this propeller would, in theory, move the boat 23" forward for every full turn. The right pitch lets your Suzuki 150-300HP outboard 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 21".
- ✔ Rule of thumb: a change of 1" in pitch moves full-throttle engine speed by roughly 150–200 RPM.
Other pitches for your Suzuki 150-300HP outboard:
- 15" pitch (15" diameter) – the lowest pitch in the range – maximum thrust for heavily loaded boats, pontoons, workboats or towing.
- 17" pitch (14.8" diameter) – a low pitch – stronger acceleration and pulling power for heavier loads, towing and water-sports.
- 19" pitch (14.5" diameter) – a mid-range pitch – balanced all-round performance and the usual starting point.
- 19" pitch (15.3" diameter) – a mid-range pitch – balanced all-round performance and the usual starting point.
- 21" pitch (14.3" diameter) – a high pitch – more top speed and lower cruising revs for lighter, faster hulls; roughly 300–400 RPM more at full throttle than 23".
- 21" pitch (15.3" diameter) – a high pitch – more top speed and lower cruising revs for lighter, faster hulls; roughly 300–400 RPM more at full throttle than 23".

Questions & Answers
Will this propeller fit my Suzuki 150-300HP outboard?
It fits Suzuki 150-300HP outboard engines with a 4 3/4" gearcase, 15 tooth spline. Check the fitment table above and compare the size stamped on your current propeller (14.2" × 23") before ordering.
Should I choose 23" 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, 21" 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 (4512-142-23) 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?
No. This propeller has a traditional pressed-in rubber hub and fits straight onto your propeller shaft with your existing thrust washer and nut.
Is this a left-hand propeller?
Yes – this is a left-hand (counter-rotation) propeller for counter-rotating engines or the counter-rotating side of twin installations. Check your engine rotation before ordering.
Note: Please verify your engine's gearcase size, spline count and propeller size against the references above before purchasing. Domain: 4boats.co.uk
