Catalina 380 Westerbeke overheat

westerbeke-issue-1

New to association and getting familiar with boat.  Ran across attachment in documents provided by previous owner relating to an overheat problem with the 42B4.  Called Westerbeke  and Catalina support trying to find out if it applied to my boat, hull 191.  Catalina support related that it was discovered in earlier models and fixes were made; Westerbeke  said same.  I asked if thermostat should still be at 160 degrees if fixes were made.  I was advised to keep it at 160 degrees.  I had the engine services by my mechanic and he replaced it with a 180 thermostat, as specked by Westerbeke.  He argues to keep it at 180; I’m on the fence.  Any experienced advice appreciated.

Yanmar 3JH4E Cold Weather Starting

The Yanmar 3JH4E does not have glow plugs, but Yanmar instead offers an optional intake Air Heater to help with cold weather starting. The engine on our 387 does not have this optional heater, but I believe the blue “glow plug” wire from the start switch is run all the way through/to the engine wiring harness (the 3-conductor plug on the Yanmar harness), and from there on to the stbd side of the engine block itself. Meaning, I think, that all of the wiring is in place so you could just drop in the optional intake Air Heater and plug it in if you were inclined to. Jeff Houston, TX C387 #90

Dripless Shaft Seals

I am considering changing from the present PSS shaft seal system to the Sure Seal. I am getting conflicting opinions regarding the SureSeal. On one hand there are those that claim that the SureSeal system is much more reliable and a change of seals is possible while the boat is on the water. On the other hand, there are those that claim that SureSeal may not be appropriate for 3 cylinder engines and below because of the excessive vibration of these smaller engines. Any experience or opinion on this topic is very much appreciated. I.J. Perez S/V Windseeker II C387 #128 NJ

Yanmar 4JH3E Heat Exchanger flush

Expanding on earlier posts on the same topic, I am please to share some lessons learned from my recent challenges of increasing engine temperature and the decision to remove the heat exchanger for a flush. The engine manual calls this out as due every 4 years or 1000 hours so definetly a routine mainenance task. Following is a descriptive explanation of the process to both remove and reinstall the heat exchanger as follows: Drain the coolant using the drain cock located on the aft side of the heat exchanger housing. You will need plenty of dry rags and a container to collect the coolant ahead of disposal. Loosen the alternator adjustment bolts and remove the v belt allowing the alternator to drop away from the front of the heat exchanger. Remove the 2 hex key bolts holding the fwd heat exchanger cap in place. Tap the cap on the side
