Thanks for the feedback. However comparing oil pressure in a truck (which uses a Hi pressure pump) vs a boat with a low pressure pump is apples and oranges. My 71 454 Corvette is at about 15 psi hot idle after a hard run in the summer. Jumps back up to 60 cruising. So I guess you are going to tell me I need to pull that motor out right??? It's been that way for 8 years. Well it may not be perfect but no way I'm pulling the motor out at the start of the boating season when I am within the Merc specs. 99% of my boating consists of cruising at 3200 rpm 2 mi each way from my marina to the cove to anchor for the day so I'm going to take my chances. If I hear noise or get below the 10 psi per 1000rpm then I will pull the engine.

OK!! Just trying to help.

I sometimes wonder why guys like you, come on oso asking for advice, when you already know all the answers.

Good luck with the 10psi oil oil pressure after a 3500RPM run. I'll stick to my 35-45psi idle after a 6000RPM run.

Never sd I had all the answers. I had what I thought was low oil psi. So I posted asking for advice. Someone suggested to check the oil lines. I did, saw that they were indeed wrong. I corrected it. Oil pressure is better and now within merc specs (vs before it was below spec) The forums did their job!! Its not as good oil psi as your boat, but doesn't mean my engine is going to blow up because it doesn't idle at the same psi as yours.

I will gladly post an update at then end of the summer (which in Texas is October) on how the engine is doing.

EAGLE CRANK &RODS you get what you pay for:lolhit:

I find it interesting, that you had the same problem a few years back. And ultimately, you had it torn down, to find the bearings shot. And here you are again, with the same problem, arguing that it's just fine.

Well if you read my recent post, you'd see that the hoses were hooked up backwards and have been that way since I bought the boat. I corrected the hoses this past week and the pressure has come up to factory specs. It never figured out the prob the first time and so I pulled the motor and had it rebuilt. The best oil pressure I could get was about 30 psi cold and near zero at hot idle. Again, that was with the dash gauge,not a mech gauge checking hot idle. In May of that year everyone on OSO was saying "pull the motor now, don't run it another minute...you're going to throw a rod throw the block and the hull and the boat will sink!!!" I ran it all summer until September, no noises, no problems.

I will concede the pressure is about 10 psi low across the board where an engine with 32 hrs should be, but its still within spec so I'm not going to put my boat out of service for most of the summer because of this. I probably caused some bearing damage running it for the 30 hrs with oil going the wrong way through the filter. I am going to pull the motor in the fall and have the bearings checked and if they are worn I'll have them done again.

Once again, you have it all figured out.:bong::bong:

Youve Been a oso registered member for several years, and in your 100+ posTs, all you have participated in is your questions and issues regarding YOUR boat problems.

There's lots of members on here who enjoy helping people out, including myself. What I don't enjoy, is guys like you, who bring nothing to the table besides your self inflicted problems, in the quest for a free fix. And when a free fix is or isn't provided, you disappear back into your own world.

No forum participation, just help me me me. Initially in this thread I felt bad because I thought you had been screwed by a shoddy engine builder. I can now see, you sir, are your own worst enemy.

Best of luck with the low oil psi, Worn bearings, no oil temp gauges.

Well the whole purpose of the forum is a place to get help with questions..My hoses were backwards from the previous owner. I never noticed it. Now,thanks to someone else reply, it made me doublecheck the hoses and correct the problem. Had I listened to you, I would be pulling my engine out right now and missing the entire season, when 2 merc mechanics told me this past week not to worry. As far as not participating in other posts, I have actually helped a lot of folks on Iboats.com. I would rather not post misinformation than be an alarmist like yourself, sir...

red,just fyi,454 truck engine has a standard volume&pressure pump,most have a 5 qt oil pan,and a hv pump would suck the pan dry.but what the h ell,who needs oil pressure anyway.

fixx
 

Did someone say fix?

Sorry im going to have to agree with joe on this one,,and about the oil pressure issue,its only a mate of time before you start a new trend '' where to find a good used 502 block,,i can cut the crank .050 under and buy a good used set of rods...

back to pressures..all honesty you may have oil pressure but is it enough to keep the bearings happy?.. as comparison my 92 big block suburban has 463,000 miles on a unopened engine and the oil pressure is 20 at idle and 45 cruising with 10w30 mobile one..my sc 600's are 45 and 65 at cruise ans yes both engines are equal..
