Deep-dive articles, maintenance tips, and buying guides for every type of marine propulsion. Written by people who spend weekends on the water, not in an office.
We don't publish filler. Every piece is researched, tested where possible, and reviewed by someone who's actually worked on boats.
We don't let advertising relationships dictate what we write or recommend. If a product underperforms, we say so. If a technique is overrated, we explain why. Our readers trust us because we've never given them a reason not to.
No paid placements · Transparent reviews · Fact-checked
We go further than surface-level explainers. Our technical articles cover hydrodynamics, rake angles, gear ratios, and cavitation plate positioning — but always with enough context that a first-time boat owner can follow along without getting lost.
Spec accuracy · Clear diagrams · Practical application
Reader questions shape our editorial calendar. We read every comment and email, and regularly turn recurring questions into full articles. Boatsprop isn't a broadcast — it's a conversation between people who genuinely love being on the water.

Feedback from the marina, the workshop, and the open water.
“I've been maintaining my own boat for twelve years and Boatsprop is the only blog I actually trust when I need real propeller information. The stainless vs aluminium comparison alone saved me from a very expensive mistake.”
“As a marine mechanic in Madrid, I recommend Boatsprop to customers who want to understand their equipment better. The technical content is accurate without being inaccessible. That's rare online.”
Boatsprop started in 2019 as a personal project by a group of Madrid-based boating enthusiasts who kept finding the same problem: most online content about propellers was either too shallow or buried in manufacturer marketing. We built the blog we wished existed — technical enough to be useful, readable enough to enjoy over coffee before a weekend on the water.
Every article starts with a question we've seen in forums, marina chats, or reader emails — not a keyword tool.
Our team consults marine mechanics, pulls manufacturer specs, and whenever feasible, tests gear on actual vessels near Madrid.
No padding, no jargon for jargon's sake. If a term needs explaining, we explain it. The goal is clarity, not word count.
Propeller technology and best practices evolve. We revisit and refresh our most-read content so it stays accurate and useful.

Real examples of how our guides helped boat owners fix problems, save money, and get more out of every trip.
Propeller SelectionAfter reading our pitch selection guide, a reader from Valencia realised his engine was over-propped, causing excessive fuel burn. Swapping to the correct diameter saved him €400 in fuel over one summer season and improved his cruising speed by 3 knots.
TroubleshootingOur guide on propeller-induced vibration was shared over 2,000 times in boating forums after readers confirmed it helped them identify blade damage and hub wear that mechanics had missed. It remains our most-read troubleshooting article.
MaintenanceOur annual propeller winterisation guide has been used by thousands of boat owners across Spain and Portugal. It covers removal, inspection, greasing, and storage in a format simple enough to follow in a cold boatyard.
From pitch and diameter to cavitation and material choice — we cover every angle of marine propulsion in plain language.
Confused by pitch, blade count, or material? Our guides break down exactly what to look for based on your boat type, engine, and typical use case.
Step-by-step articles on cleaning, balancing, and replacing props — with photos, torque specs, and the mistakes most people make the first time.
Learn how prop selection affects top speed, fuel consumption, and hole shot. We explain the physics without turning it into a lecture.
Aluminium vs stainless, 3-blade vs 4-blade, cupped vs flat — we compare real-world performance so you can make the right call for your setup.
Honest, hands-on reviews of props from Solas, Mercury, Yamaha, Michigan Wheel, and others — no sponsored fluff, just what actually works.
Two of the most misunderstood problems in boating. Our deep-dive posts cover causes, symptoms, and how the right prop choice prevents both.
Common questions from readers who are new to propellers or looking to go deeper on the technical side.
Our content is written by a core team of boating enthusiasts, a marine mechanic consultant, and a naval engineering graduate. All articles are reviewed for technical accuracy before publishing.
No. We do not accept payment for positive reviews. Some articles contain affiliate links that help fund the blog, but these never influence our opinions or recommendations.
We have a full guide on this. The short answer: start with your WOT RPM range, check your engine manual, and use our pitch calculator article to narrow it down. If you're still unsure, drop us an email with your setup details.
Absolutely. Reader suggestions are one of our main sources of new content. Use the contact form or leave a comment on any article — we read everything and respond when we can.
Yes. We cover all three propulsion types, including specific content for high-performance outboards, inboard shaft drives, and stern drive units like Volvo Penta and Mercruiser.
