If you see a trickle of water from the limber hole above the shaft log on your 1986 thru 1990 Pearson 36-2 or P38, it is a good probability that a bottom weld on the stainless steel water lift muffler is corroded and is leaking. This happened to us this past summer while on a two month cruise. But don’t fret, there is a relatively inexpensive replacement for the muffler.
Centek Industries, a major manufacturer of fiberglass, water lift mufflers has the dimensions and calculations for the Pearson muffler and can supply a new unit in about two to three weeks. Here is what you will need to know:
Centek Industries, Inc
116 Plantation Oak Dr
Thomasville, Ga. 31779
800-950-7653
www.centekindustries.com
Part number: X06258
Description: 2” X 2” Vernalift, Deaton Yacht Service
(Note, Deaton was the first yard to have one made in 2005).
This is a special order so it must be ordered by a yard or retailer. Centek only sell’s through distributors.
The price in July, 2008 was $265 plus shipping, about $20.
INSTALLATION:
This first picture shows the old muffler, upside down. The pipe on top is the inlet pipe that enters the bottom of the muffler. The pipe on the side is the outlet.
The inlet pipe may need to have about two inches cut off to permit the unit to clear the support beam as it is removed. One or both of the fuel lines may need to be disconnected from the fuel tank for clearance on removal. The new muffler is smaller so it will fit into the boat with the fuel lines in place.
The second picture is of the new muffler, also upside down. Note that the inlet pipe is shorter than the original. This will entail replacing the exhaust hose from the engine with one about twelve inches longer. We found that hose made by Vetus is much more pliant and will make the two bends needed very easy.
The third picture shows the strut backing plate, located under the muffler. One of the major benefits of the new muffler is now being able to see the backing plate with the muffler in place. We found that we did have a “weeping” of water from the plate seal when the engine was running at cruising speed.
The last picture is of the new muffler in place. There is enough clearance to tighten the hose clamps on the inlet pipe as you set the unit in place. The clamps can also be inspected with the muffler in place.
The Centek muffler is round and is a smaller volume than the original and I was concerned that the sound would be louder. It was of no concern. The Centek muffler is as quiet or softer at the transom outlet and has less “rumble” in the galley area next to the companion way steps.
