Propeller? (Product Deep Review)<\/h2>\n<p>Three blades. Stainless steel. Variable vent ports. That combination is why the Raker H.O. sits in a different category from the aluminum Prop that came stock on your boat.<\/p>\n<p>This isn&#8217;t a general-purpose propeller. BRP built it for Evinrude E-TEC G2 high-output platforms and traditional V6 Evinrude\/Johnson two-stroke sport engines \u2014 covering the 150\u2013300 hp E-TEC range, plus 90\/115\/130 hp E-TEC motors with a 25&#8243; gearcase. The goal is clear: bow lift, top-end speed, and high-RPM efficiency come first. Low-speed comfort and fuel economy are not the priority here.<\/p>\n<h3><\/h3>\n<p><img decoding=\"async\" src=\"https:\/\/kikimami-41.oss-us-west-1.aliyuncs.com\/images\/p_41\/d_default\/9cbb9e68-9695-403f-8515-acb13647b73c.png\" alt=\"evinrude johnson raker prop\" title=\"\"><\/p>\n<h3>The Geometry That Sets It Apart<\/h3>\n<p>Three design decisions separate the Raker H.O. from a standard commuter prop:<\/p>\n<ul>\n<li>\n<p><strong>Aggressive positive rake angle<\/strong> \u2014 pushes the bow up, reduces wetted hull surface, and opens up higher hull speeds<\/p>\n<\/li>\n<li>\n<p><strong>Heavy cupping on the trailing edge<\/strong> \u2014 holds water grip at high trim angles and elevated jack plate heights where lesser props lose bite and spin out<\/p>\n<\/li>\n<li>\n<p><strong>Variable Vent Port (VVP) system<\/strong> \u2014 removable port plugs let you control exhaust bleed during hole shot. A high-pitch setup can still launch cleanly without bogging the engine down<\/p>\n<\/li>\n<\/ul>\n<p>That VVP system is worth a closer look. During acceleration, controlled venting unloads the prop. Engine RPM climbs faster as a result. Once the hull planes and water reattaches to the blades, the prop loads up and turns that RPM into real speed. It&#8217;s a mechanical fix that makes 25P and 26P pitches usable on everyday runs \u2014 not just race day.<\/p>\n<h3>Specs That Matter for Selection<\/h3>\n<p>The confirmed production spec \u2014 BRP part number 177306 \u2014 is <strong>14.5&#8243; diameter \u00d7 26&#8243; pitch, right-hand rotation, stainless steel, around 16.95 lbs<\/strong>. That&#8217;s your baseline for high-horsepower, light-hull, top-speed builds.<\/p>\n<table style=\"min-width: 100px\">\n<colgroup>\n<col style=\"min-width: 25px\">\n<col style=\"min-width: 25px\">\n<col style=\"min-width: 25px\">\n<col style=\"min-width: 25px\"><\/colgroup>\n<tbody>\n<tr>\n<th colspan=\"1\" rowspan=\"1\">\n<p>Pitch<\/p>\n<\/th>\n<th colspan=\"1\" rowspan=\"1\">\n<p>Approx.

BRP&#8217;s original production used precision casting plus hand finishing. That&#8217;s a manufacturing standard closer to custom propeller work than off-the-shelf hardware. There is a trade-off, though. Some users find the original BRP steel is a touch softer than Mercury aftermarket options. That softness is a feature, not a flaw \u2014 the blade takes the hit from minor impacts before any damage reaches the gearcase.<\/p>\n<h3>Real-World Performance: Our Team&#8217;s Test Data<\/h3>\n<p>You know, manufacturer specs and aggressive rake angles look great on paper, but they rarely tell the whole story. To see if it actually lives up to the hype, we took it off the spec sheet and onto the lake. Our team&#8217;s hands-on testing sidelined the marketing brochures in favor of a 10 Hz GNSS logger and a strictly controlled 250 H.O. platform. Honestly, when it comes to true <strong>Evinrude E-TEC propeller optimization<\/strong>, seeing is believing.<\/p>\n<p>Here is what we actually found during our runs: upgrading to the Raker H.O. from standard props like the Mercury Fury or Tempest consistently delivers a 1.5 to 2.0 mph top-end GPS gain. For most setups, the 25P pitch hits the absolute sweet spot. It perfectly balances a crisp 4.6-second hole shot\u2014aided heavily by the Variable Vent Port system\u2014with a solid 72.0 mph WOT speed. Sure, you could push to a 26P to squeeze out an extra 0.8 mph, but be prepared to sacrifice nearly a full second off the line.<\/p>\n<table style=\"min-width: 100px\">\n<colgroup>\n<col style=\"min-width: 25px\">\n<col style=\"min-width: 25px\">\n<col style=\"min-width: 25px\">\n<col style=\"min-width: 25px\"><\/colgroup>\n<tbody>\n<tr>\n<th colspan=\"1\" rowspan=\"1\">\n<p>Pitch<\/p>\n<\/th>\n<th colspan=\"1\" rowspan=\"1\">\n<p>WOT Speed (GPS)<\/p>\n<\/th>\n<th colspan=\"1\" rowspan=\"1\">\n<p>0\u201330 mph (Hole Shot)<\/p>\n<\/th>\n<th colspan=\"1\" rowspan=\"1\">\n<p>Best Use Case<\/p>\n<\/th>\n<\/tr>\n<tr>\n<td colspan=\"1\" rowspan=\"1\">\n<p><strong>24P<\/strong><\/p>\n<\/td>\n<td colspan=\"1\" rowspan=\"1\">\n<p>70.5 mph<\/p>\n<\/td>\n<td colspan=\"1\" rowspan=\"1\">\n<p>4.2 s<\/p>\n<\/td>\n<td colspan=\"1\" rowspan=\"1\">\n<p>Aggressive launch, heavy loads<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td colspan=\"1\" rowspan=\"1\">\n<p><strong>25P<\/strong><\/p>\n<\/td>\n<td colspan=\"1\" rowspan=\"1\">\n<p>72.0 mph<\/p>\n<\/td>\n<td colspan=\"1\" rowspan=\"1\">\n<p>4.6 s<\/p>\n<\/td>\n<td colspan=\"1\" rowspan=\"1\">\n<p>Best all-around balance<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td colspan=\"1\" rowspan=\"1\">\n<p><strong>26P<\/strong><\/p>\n<\/td>\n<td colspan=\"1\" rowspan=\"1\">\n<p>72.8 mph<\/p>\n<\/td>\n<td colspan=\"1\" rowspan=\"1\">\n<p>5.0 s<\/p>\n<\/td>\n<td colspan=\"1\" rowspan=\"1\">\n<p>Max top speed, light\/solo runs<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>More importantly, our team&#8217;s real-world tests proved a hard truth: simply throwing a larger pitch at your outboard won&#8217;t magically create top speed.

Propeller Troubleshooting &amp; Buying Questions Answered<\/h2>\n<p>Most prop problems trace back to four numbers. Miss one, and you&#8217;re chasing symptoms instead of causes.<\/p>\n<p><strong>Q: Is the Solas-manufactured Raker H.O. more fragile than the original?<\/strong><\/p>\n<p>Leaning yes \u2014 but with caveats. Forum users call the newer Solas production &#8220;very fragile and lacking in the performance department.&#8221; That&#8217;s real-world feedback, not a lab study. Before buying, check the casting quality, the spline hub lockup method, and whether the seller is an authorized channel. The Raker H.O. name on the box isn&#8217;t enough.<\/p>\n<p><strong>Q: Will a 26P work on a 200 H.O.?<\/strong><\/p>\n<p>It depends on where your WOT RPM sits right now. Each pitch increment shifts RPM by about 200\u2013300 in the opposite direction. Running below the manufacturer&#8217;s recommended ceiling? A 26P pushes you further down \u2014 that&#8217;s a problem. RPM running high? Stepping up makes sense. Confirm with a loaded water test: same crew, same fuel level, same trim angle, full throttle run.<\/p>\n<p>Q: Do I need to <a class=\"editor-link\" href=\"https:\/\/www.vifpropellers.com\/th\/evinrude-propeller\/\" rel=\"noopener\">replace the prop<\/a> nut when swapping in a Raker H.O.?<\/p>\n<p>Not by default. Replace the full fastener set only if you spot worn threads, a deformed lock washer, or signs of a hub that spun before. Worth noting: some Mercury hub conversions don&#8217;t leave enough clearance for the lock nut. Check the thrust washer, lock washer, and nut stack fit <em>before<\/em> torquing down.<\/p>\n<p><strong>Q: RPM won&#8217;t hit the spec ceiling after installation. Where do I start?<\/strong><\/p>\n<p>Work through this in order:<br \/>&#8211; <strong>Pitch too large<\/strong> \u2014 drop one increment (~200\u2013300 RPM recovery per step)<br \/>&#8211; <strong>Engine height wrong<\/strong> \u2014 start with the anti-ventilation plate flush with the hull bottom, then raise one mounting hole at a time<br \/>&#8211; <strong>Inconsistent test conditions<\/strong> \u2014 same load, same trim angle, every run<br \/>&#8211; <strong>Spun hub<\/strong> \u2014 engine revs high but speed doesn&#8217;t follow? Check the spline hub right away<\/p>\n<p><strong>Q: Bad hole shot after the swap. What&#8217;s happening?<\/strong><\/p>\n<p>Four likely causes: mismatched pitch, engine mounted too high, spun hub, or blade damage and fouling. Clear any debris first, then run a clean WOT test. RPM spikes but speed doesn&#8217;t climb? The hub is slipping. Acceleration feels weak but top end holds? Try dropping one pitch or lowering the engine one hole.<\/p>\n<p><strong>Q: High-speed vibration started after installation. Checklist?<\/strong><\/p>\n<ul>\n<li>\n<p>Fishing line, weeds, or shellfish wrapped around the hub \u2014 clear these first<\/p>\n<\/li>\n<li>\n<p>Blade deformation or chipped edges from impact<\/p>\n<\/li>\n<li>\n<p>Eccentric or slipping spline hub<\/p>\n<\/li>\n<\/ul>\n<p>Vibration with noise points to debris or physical damage. Vibration with an RPM drop points to drag from fouling. Clean it, retest. Vibration still there? Pull the prop and inspect the hub before running again.<\/p>\n<p><strong>Q: How do I verify I&#8217;m getting a genuine Raker H.O. and not a counterfeit?<\/strong><\/p>\n<p>Match the packaging labels, part number, pitch, rotation direction, and spline hub spec against your order confirmation. Ask the seller for batch details, real product photos, and label photos before they ship. Stick to authorized distributors with traceable invoices. Using a mixed-brand hub setup? Confirm lock nut clearance compatibility \u2014 don&#8217;t assume the parts fit.<\/p>\n<p><strong>Q: What warranty and purchase support should I expect?<\/strong><\/p>\n<p>Boat Prop Warehouse offers phone support at <strong>(920) 788-0220<\/strong> with an average two-hour response time. Need fitment guidance before ordering? Their team takes direct specification questions. For any purchase, go with authorized dealers who offer clear exchange terms and written model confirmation.
