Big Blue "Su" Saves Fuel

Big is Beautiful. We’ve been selling Isuzu engines since the ‘60s and this is the biggest factory marine version to come to the US. With a 505-hp (M-1) tugboat rating @ 1800 rpm, up to 671 hp (M-3) seiner/longliner rating at 2100 rpm, the 6WG is so well balanced it idles at 450 rpm. It’s the most fuel-efficient Diesel we’ve seen in this horsepower range. This is the engine for longevity, durability, & quiet. Isuzu quality control is legendary & they withstand a lot of abuse—always a popular feature in the fishing industry.

This Isuzu owes its efficiency & endurance in no small part to the high-pressure common-rail fuel (HPCR) system and dry-fit chromium-plated cylinder liners. With 4-times the hardness of cast-iron liners and much lower friction levels, the liners themselves don’t show any wear after 1000s of hours of use. We have literally had engines overheat, seize a piston, cool down, restart and run for years, usually without damage to the cylinder liners.

Dry-fit liners aren’t susceptible to water erosion because there is no direct water contact with the liner–no possibility for pits or cavitation, no O-rings to fail that could leak water into the crankcase. In fact it’s the same cylinder-liner system used in their smaller engines. You want a tough reliable main from 505 hp to 671 hp, stop by our showroom at 338 West Nickerson St., in Seattle.

The 6WG1 is going to replace a lot of engines out there. All you 58- to 100-footers take note. 6WG1 Fuel Economy—The Proof is in the Repower
