7 months ago August 3, 2020 at 10:08 am Starboard is burning more fuel, higher temp, slightly higher oil pressure and minor darker exhaust vs the portside. (only happens when 2500+ rpms / cruising out) Any ideas? heat exchanger? too much fuel/burning rich? Thanks! Engines: twin turbo diesel yanmar 4lha-ste

Yanmar motor mounts (isolaters)
This topic has 5 replies, has 3 voices, and was last updated by
3 years ago January 22, 2018 at 8:45 am I was going to call Tony and talk to him about my motor mounts (Yanmar 4LHA-STE) and what he would suggest for replacements. I decided to ask my questions here so that others may learn as I do. I have really old style Yanmar mounts which were installed during my repower by Tony in 2000, thus they are 18 years old. I have attached a picture that shows one of the mounts. There are more and better pictures on this site in the section on my repowe…

So I can not really say anything about which R&D mount to use. Although, I just remembered that a friend of mine just purchased some R&D mounts. I will check with him and find out which ones he got and how they work. He also has 4LHA-STEs. Standby. BillLast Post by:

Aftercooler Life Expectancy

December 13, 2017 at 10:36 am Hey guys and gals. New to the forum and to Cummins as well. Recently purchased a 32 Albin SF with a Cummins 6bta 370hp. I am planning to do most of my own maintenance however I did have a mechanic give the engine a once over survey. He had suggested possibly replacing the aftercooler due to the age of the engine and because they typically only last 7-10 years. Is that accurate? If I have it cleaned, inspected, and pressure tested would I still n…

Crankcase ventilation / fumes

December 19, 2017 at 3:05 pm Just purchased Albin with twin 6BTA5.9 270hp engines. Engines ran at 2600 -2650 rpm with normal temps and oil pressures. Oil is venting from starboard engine crankcase vent tube into bilge at normal oil levels (per “hand marked” dip stick). If I let oil go two quarts low (per dip stick), venting stops and oil level remains constant (over the last 10 hrs run time). I’m still getting a lot of fumes in salon (engines are mount…

Keep real close track of the temperature of the packing gland. Stop if need to let it cool. As the break-in come along, spray the backing gland with water to keep it cool. Cool meaning below about 140 degrees. Nothing like some pictures to point out all the bad areas on your boat. I will confess, as an old guy, I simply do no…Last Post by:

Yanmar 6LY coolant

4 years ago January 28, 2020 at 7:53 pm I know it may be beating a dead horse, but I’m having trouble understanding what coolant to use in my new to me 6LYA-STE. I’ve done research, not a lazy no search question. The literature from Yanmar is a bit outdated, they recommend Coolant from Havoline or Texaco. The Havoline ELC is now orange. I have read that the red coolant is what is to be used. The Havoline ELC (orange) is silicates and nitrate free OAT. Delo ELC is red, sil…

January 5, 2020 at 9:37 am The manual is far from gospel ….. All environments and sea water conditions will play varying levels of havoc.

If the pump has not been serviced in 8 years I gather that neither has the remainder of the seawater circuit. Now is the time. Best is to pull all from the engine and ben… 25 Replies

6 years ago April 5, 2018 at 11:18 am In general, for my search for a boat I have searched only for those with Cummins Engines.

However, there are some boats that I might consider that come up with the Yanmar engines such as the 6LPAs and the 240HP 4 cyl. I have eliminated the 6 cyl from consideration for such things as Valve seal issues and more stringent maintenance requirements. But how about the…
