I posted in the FB group but I'll post here for the non FB crew...
I have the 340 etx cat running on mefi5. I've been dealing with low oil pressure.
Last year it went into protection mode with the 3000 rpm limit, and I wasn't low on oil. Tried lots but ultimately a fresh oil change fixed the pressure that I didn't even bother using the mechanical gauge last fall.
I still gave it a fresh oil change and on the 3rd time out this year I got protection mode and the code just motoring with no ballast at 23 to 25mph. Added a quart and it improved (I found threads where the "fix" for the oil pickup on the bow side of the oil pan was too add more oil per indmar).
I given the oil pressure improved dramatically last fall with an oil change, I decided I'd swap out to a different filter. I'd been going cheap and easy before using whatever was convenient at Walmart or Amazon and had been using the Fram ultra guard. Now I believe that they are ultra-crap.
I threw on a Moroso racing filter and it was a very noticeable improvement on my digital gauge. I also put on a new digital oil pressure sender, even though I don't think that was the problem as my dash gauge and the psi off the ECU leveraging the digital switch had been reading consistently.
I also stumbled on this spec for psi on the indmar engines and was shocked at how crazy low indmar says our engines are spec'd for. I'd love to hear some thoughts on that. (3psi @ idle and 18psi @ 2k rpm?!?)https://uploads.tapatalk-cdn.com/20240603/9ad02e6843d6ac0feccd36d55f23da9b.jpghttps://uploads.tapatalk-cdn.com/20240603/3d7b1ccb94581b45aeaa1df35d85c0a8.jpg
