[K1W1]

Hi,

Marmot- 12 yrs ago I was involved in a boat with 3306 Gensets rated at 160 ekw @ 1500 RPM. These were ok with the wet manifolds but in an effort to clean up the exhaust stack which was fed into UNIKAT Catalytic converters the wet manifold and turbo turbine casing were exchanged for dry ones off a 66Z Engine ( Industrial). The engines were never bench tested with this arrangement. The temps in the box were extreme and as the Air Cleaner inlet was also in the box the inlet temperature was often 50 Deg C which just made the exhaust gas hotter. The manifold used to glow cherry red under heavy load and we had numerous failures of turbos and the manifolds (11turbos were done on 2 engines in the first 12 months in service)

At the time the published CAT Data sheet gave the rating as being normal up to 50 Deg C.

The whole lot was eventually changed for the original style wet ones and we did not have anymore failures although the soot filters did require cleaning occasionally after this.
