HVS Ignition Cap & Rotor Kit, V8 | Crusader RP173098
Get the complete ignition solution your Crusader V8 marine engine demands. This HVS-compatible cap and rotor kit delivers the precision fit and reliable spark timing your boat needs for dependable performance on the water. Designed specifically for late-model GM V8 marine applications, this genuine Crusader assembly (RP173098) keeps your engine running at peak efficiency.
Maintaining your marine engine's electrical system is vital for safety. Consequently, the HVS Ignition Cap & Rotor Kit, V8 | Crusader RP173098 is a top-tier choice. This kit is specifically engineered for High Voltage Switch (HVS) ignition systems. Because marine environments are unforgiving, you need parts that resist moisture. Therefore, this OEM Crusader kit provides the durability required for heavy offshore use. By choosing this kit, you ensure your V8 engine performs at its peak.
First of all, this kit is designed for 2002 and newer PCM and Indmar engines. Specifically, it fits the popular 5.0L and 5.7L GM-based V8 powerplants. Since these engines use a "flat cap" design, the fit must be exact. In addition, the kit includes the RA108009 distributor cap and the R103011 rotor. These components work together to deliver a consistent, high-voltage spark. Furthermore, the use of premium PBT and PET plastics prevents housing warpage.
Corrosion is the leading cause of ignition failure in salt and freshwater. However, the Crusader RP173098 kit features solid brass inserts. Unlike aluminum alternatives, brass resists electrical pitting and oxidation. Consequently, you receive a cleaner electrical path for a more efficient burn. This leads to smoother idling and much better throttle response. Moreover, the high strength-to-weight ratio protects against thermal cracking during long runs.
Simple Maintenance for Maximum Efficiency
Installing this kit is a straightforward way to boost your boat's fuel economy. Since a worn rotor can cause misfires, replacing it annually is a smart move. In addition, this kit is designed to reduce RFI interference with your onboard electronics. Therefore, your GPS and sonar equipment will remain clear and accurate. It is recommended to use Torx T-15 and T-20 drivers for a professional installation. Ultimately, this simple tune-up prevents costly downtime during the peak of the season.
Choosing genuine Crusader parts means you are following factory specifications. While aftermarket kits exist, they often lack the precise tolerances of the RP173098. Since this kit replaces Mercury numbers 898253T29 and 8M0061335, it offers versatile compatibility. Furthermore, the specialized gaskets and seals protect the internal distributor components from humidity. As a result, your engine will start faster and run more reliably. Don't settle for less when it comes to your boat's ignition health.
This kit fits 2002 and newer PCM 5.0L and 5.7L engines. It also fits 2006 and newer Indmar 5.7L engines and various MerCruiser V8 models.
Why is it called an HVS ignition system?
HVS stands for High Voltage Switch. This system uses a specialized flat-style distributor to manage high-energy sparks in modern fuel-injected engines.
How often should I replace my cap and rotor?
For best results, replace these parts every 100 hours or once a year. This prevents the buildup of corrosion that leads to hard starting.
No, the rotor and cap are designed for a direct "drop-in" fit. However, always ensure the mounting screws are snug but not over-tightened.

Would have been 5 stars but, I did not receive a promotional sticker with my $2000 drive unit. Just kidding, everything was great!
Great company to work with!
Ordered a Piranha Propellers Complete A-Series 4 Blade Propeller from Macomb Marine Parts and even though we’re international, it arrived in just over a week — fast and reliable service. The propeller itself is a real lifesaver. We had the same model before, and after hitting a rock that damaged two blades, we were able to swap them right on the water and make it back to the marina without issue — something you simply can’t do with a regular aluminum prop. For peace of mind we decided to buy a complete new set (hub and blades) since an impact like that could cause hidden damage, but the system really proved its worth.

Excellent part.
I couldn’t find a Piranha propeller dealer near me in Canada but found Macomb Marine Parts who could deliver to me. The order process was smooth and I was even contacted via email for clarification regarding blade shape and they were very helpful in choosing the best shape for my purposes.
I can’t comment on the prop’s performance yet as we haven’t had the boat in the water yet.
Perfect replacement. thank you
Perfect replacement
Perfect match to the original Chris Craft blue. Competitive price and delivery was quick
Great Product, easy to install, work well
Obtaining magnesium anodes to install on the OMC Cobra (SX-C) sterndrive, for fresh water use. Received the anode within a week of ordering the part, which is not going to be installed until Spring.
