I have recently come up with a way to direct engine fumes and oil mist out of my Cat 34 1992 with an M-35 engine.  I attached a small inline strainer to the blow by hose.  I removed the metal strainer insert and filled the strainer with steel wool.  I then attached a plastic water hose to the exit connection on  the strainer and directed the hose to the transom of the boat.  I installed a fuel overflow breather to the stern of the boat...it looks just like the fuel overflow for the fuel tank...and connected the hose.  Since I have made this modification I no longer have engine fumes lingering down below when motoring and I no longer have an oil mist all over my engine.  I came up with this solution when I learned that it was not a good idea to attach the blow by hose to the air filter....could cause a runaway diesel.  I can reach around in the cockpit to feel pressure coming out of the overflow breather and I occassionally check the strainer for an accumulation of oil that could block the exit of gases and oil mist.  This may be an extreme concern to most people owning catalina's but I have motored hard for as long as 6 days in my voyages and have covered over 10,000 miles in the last few years and the fumes were a problem for my crew and me.  I would appreciate any feed back on this subject.

Partager was zapped by lightening on July 13, 2008.  All electronics have been replaced, repaired etc...The last problem to resolve is the Tachometer/ Hour meter...the old tach had 4 dip switches the new ones have 6+8.  The tach leg has been replaced by Seapower..but we have not been able to get the right combinations of dip switches to make the tachometer work...are there any Cat 34 owners that have a Seapower system that converts the alternator/generator power to 5000 kw.  if so can you let me know what the Dip switches need to be set on to get a good steady reading...Bob Fleege Pensacola Fl  bobpyc1776[no spam] at [no spam]aol.com
