Is 17" the Right Pitch for Your Boat?
A 17" pitch means this propeller would, in theory, move the boat 17" forward for every full turn. The right pitch lets your Volvo Penta SX sterndrive 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 – the next size up for this engine is 19".
- ✔ 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 15".
- ✔ Rule of thumb: a change of 1" in pitch moves full-throttle engine speed by roughly 150–200 RPM.
Other pitches for your Volvo Penta SX sterndrive:
- 15" pitch (14.8" diameter) – the lowest pitch in the range – maximum thrust for heavily loaded boats, pontoons, workboats or towing; roughly 300–400 RPM more at full throttle than 17".
- 19" pitch (14.3" diameter) – the highest pitch in the range – maximum top speed for light, fast hulls running lightly loaded; roughly 300–400 RPM less at full throttle than 17".

Questions & Answers
Will this propeller fit my Volvo Penta SX sterndrive?
It fits Volvo Penta SX sterndrive engines with a Volvo SX drive gearcase, 19 tooth spline. Check the fitment table above and compare the size stamped on your current propeller (14.5" × 17") before ordering.
Should I choose 17" or a different pitch?
Keep the same pitch as your current propeller if the engine reaches its rated full-throttle RPM. If it over-revs, 19" is the next step up. If it struggles to reach rated RPM, 15" 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 (8613-145-17) 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.
Note: Please verify your engine's gearcase size, spline count and propeller size against the references above before purchasing. Domain: 4boats.co.uk
