Repowering a classic 1987 Island Packet 27 is a significant investment that can breathe new life into a world-class pocket cruiser. While the original Yanmar 2GM20F is a legendary workhorse, replacing it with a modern, fresh-water cooled diesel—along with a new fuel tank—will vastly improve your reliability, fuel economy, and peace of mind for years to come.
At Yes Centers, we specialize in professional dockside marine services throughout Kemah and the surrounding 30-mile radius. Since your boat is currently at the Kemah Boardwalk Marina (KBM), our technicians can easily coordinate the entire repower process right at your slip or a local yard.
The Repower Process for an Island Packet 27
Replacing an engine in a full-keel cruiser like the Island Packet 27 requires a meticulous approach to ensure the new power plant integrates perfectly with your existing hull and systems.
1. Selecting Your New Yanmar
Most owners repowering from a 2GM20F look toward the Yanmar 3YM20. It offers a similar footprint but provides smoother operation, easier maintenance access, and modern electronics.
Benefits: Reduced vibration, better charging capacity (60A+ alternator), and meeting current EPA emissions standards.
2. Fuel Tank Replacement
Replacing the fuel tank is a “best practice” during a repower, especially on a vessel from 1987.
The “Clean Slate”: Over 35+ years, aluminum tanks can suffer from internal pitting or “algae” buildup.
Our Process: We remove the old tank, inspect the surrounding stringers, and install a new, custom-fabricated aluminum or high-density poly tank with all-new USCG-approved fuel lines and a modern filtration system (like a Racor 500 series).
3. Alignment & System Integration
A repower isn’t just about the engine. Our dockside team also handles:
Engine Mounts: Replacing old, compressed rubber mounts to eliminate vibration.
Exhaust System: Installing a new mixing elbow and water-lift muffler to ensure proper backpressure.
Shaft & Cutless Bearing: While the engine is out, we inspect the prop shaft and cutless bearing for wear to ensure a vibration-free driveline.
