Catalina 30 Muffler
Ok... so I have a 1979 Catalina 30 with our beloved atomic 4... Unfortunately a leak developed in the exhaust manifold (confirmed during rebuild) which started the dreaded stuck valve syndrome which lead to one of the cylinders becoming frozen... So my atomic 4 is currently being rebuilt... Since the engine is out and I'm trying to optimize things while engine is out (lots of room to work). My original Catalina 30 muffler intake is damaged (crushed) and I intend to replace it... Started to look around and realized that most of the waterlift mufflers I've seen seem to be much smaller volume than my original (except the one offered by CatalinaDirect which is larger). So given that this is a Catalina 30 with the known exhaust issues (limited space, possible backflow when heeling), should I be concerned about the volume of the muffler?
Thanks, Dan |

Welcome Merino
Your question is a good one, waterlift volume is one of three important factors regarding Catalina 30 exhaust systems, the other two being the hot section design and the check valve at the highest point in the downstream exhaust hose found in the port sail bin in the cockpit. Since your question pertained to the waterlift we'll stay on topic. The Catalina fiberglass waterlift is the highest volume, lowest profile model available. It has a liability though. Unless the construction has changed over the years the big flat sides tend to flex in use due to the rhythmic pressure developed when pushing out water batches. This flexing leads to cracks and leaks sooner or later, likely the reason they offer a replacement. There are other waterlifts available in stock sizes that have been used successfully by Catalina 30 owners on this forum. In order of their quality starting with the lowest they are:

Neil,
Thanks for the reply... I've been looking at the Centeks as well... However I was looking at this one in particular since it's about the same volume but lower profile... http://www.centekindustries.com/wp-c...eet.pdf?x62515 Cheers, Dan |

I had not seen that model before, perhaps a new product within the past 12 years? It certainly meets the necessary parameters and has a slightly greater volume, like 9 fluid ounces. With it, a heat shielded hot section as high as cabinetry will allow and a functioning check valve you should be good.
Please keep in mind no prolonged no-start cranking with the raw water valve open. That will overwhelm any waterlift eventually.

Hi Merino, and welcome to the forum. Just recently I replaced both my hot section and the entire hose run in my C-30. Like Neil I have the Centek 1500270 water-lift which is a "top in/top-out" unit. I have a feeling that trying to bend the hose onto the "side-out" fitting on the model (15R1163) might present a challenge since the natural run of the hose goes from the W/L up and behind the galley stove. The picture of the 15R does not seem to match the dimension drawing to the right.

Tom,
The drawing is a bit deceiving... part number 15R1163 is top in/out... Part number 15R2163 is side in top out... Cheers, Dan |
