      June 7, 2023 at 7:53 pm Iā€™m getting ready to change the oil on my ZF220A transmissions. Ā Can I use copper crush washers (instead of aluminum) for oil drain bolt and filter screen bolt? Ā Concerned about dissimilar metal interaction. Ā Thanks. Ā  C_Menz

      June 8, 2023 at 11:45 am No problem, thought maybe it was a typo we needed to fix.Ā  The input “top hose” going into the pump, drip it full of oil and bump the engine a few times.Ā  Might need to pull the solenoid wire for a no-start. Rob "Luck is the residue of good design."

      May 21, 2023 at 2:07 am Hi there, as a newbie in this forum I’d like to start my first question. My Meridian 2004 408 is equipped with two 6bta5.9 370hp engines. Sometimes – in the harbour and locks, even some dutch canals – it’s too much using both engines. May I use only one engine? Is this damaging the engines or the seals/ shafts? Regards Werner

      May 22, 2023 at 7:32 pm I am about to change the oil on my transmissions: SEA 30, per manual? Where is the filter screen? How do I clean it? I understand that I want to change the oil within 2 minutes of running it? Is there anything else I need to know? Thanks.

      May 23, 2023 at 4:45 am Yes, SAE30 and 3 liters is the listed capacity.Ā  I always check the level before draining and then measure what is removed and use that as a refill reference and then adjust slightly if needed.Ā  See the attached documents for some additional info and diagram.Ā  As to cleaning the screen, I wipe it clean, blow it out and then flush with new oil.Ā  You can use something like mineral spirits if you feel the need but always finish your rinsing/cleanin…

      May 8, 2023 at 4:43 pm Tony,   Thank you for your quick response. I did not save the filters. Just didn’t think of it but I will just check the things you mentioned and monitor it. Probably do oil samples when I get the boat 7 days south to see if I get the same results. Oil that was taken out was real clean. Only had about 300 hours on it. JR Ney
