Re: 525 efi oil pressure loss?
 

I have heard of problems with Fram oil filters. On the Oil Guy website that Hydrocruiser refers frequently to they said Frams quality was substandard.

COOL! :evilb: Great news, I have had 2 Frams collapse the element on the dyno. Thats what the customer wanted. Until he seen that happen. Now we use Wix or A/C filters. Some customers like to use K&N but just a few.

Congrats on the fix!!

I had never even heard of that happening. Mercury racing acted like it was common. I have used fram filters my whole life and have never had a problem. I'm assuming that this could happen with any filter, it just happen to be a fram filter that did it to me. I'll stick with the mecury racing filters or a wix from now on. Thanks Lucky strike for info. :drink:

I use AC Delco. $3.00 and it was rated well on the OIL GUY website. Helps a little with the Mobile 1 oil changes.

Re: 525 efi oil pressure loss?
 

I use the delco pf932c filters. extral long, allows the system to carry one extra quart of oil and that never hurts.

Don't you run the 525's also?

Glad your problem is solved & was an EZ fix.

I'm happy LSjr & I could help. Jr has a world of knowledge about boats & engines for an 18 year old.

Re: 525 efi oil pressure loss?
 

Please help. My engines idle at 220. Minutes after getting on plane they both go to 190. If they don't drop back to 190, they will slowly climb to overheat. After overheating the starbard side the other day, the oil preasure has been reading lower. I have had the engines serviced. Seems it is bypassing the oil cooler from your other remarks.
What is the fix. Any help would be greatly appreciated.

Re: 525 efi oil pressure loss?
 

How old are your impellers? Also When was your last oil change & what weight oil are you using??? Jamie / Lakeside

Re: 525 efi oil pressure loss?
 

first of all jamie is right first thing to check is impellers most common idle over heat problem is a missing blade or two

second has the boat "ate " an impeller lately if so try back flushing.......Third what filter are you running
