the oil comes out of the block goes into the cooler than the filter i take the temp off the oil filter housing before it goes back to the block.
Been running this set up ever since i built the boat.
The shop called and said they put 5 quart of oil in it and it had 80 lbs with a primmer.
Just going to pick up the motor put it in the boat hook up a mechanical oil gauge and see what happens.
And i guess go to local lake and make some laps
In my opinion, your plumbing is wrong. It should go from the block, to the filter, to the cooler, then back to the block. Here are few reasons to put the filter first.....
1. Its way easier to get 50wt oil through a filter when its still hot. By cooling the oil to 150 deg then sending it to the filter, its like trying to force gear oil through a paint strainer. You have a way higher chance of the filter going into bypass and sending unfiltered oil back to the engine when trying to filter cold oil.
2. Your temp sensor on the filter will give you more accurate idea of how hot your oil is actually getting.
3. With the filter first, at least it has a chance to keep anything bad out of the cooler.
After the cooler that could be experiencing reduced flow. Is that where you're going?
Agreed.
I just had eye surgery, so I probably didn't read that as thoroughly as I should have.
50 weight oil is 50 weight at 212°F, anything colder, oil be thicker. FYI.
Not really where I was going but a good point too. What I was getting at is with the temp being read after the cooler we have no idea how hot the oil is in the pan. Might actually be up to temp. Would all depend on how efficient to cooler is and how its plumbed (cold water or dump water).
I'm sure after reading how this thing is plumbed (out of block, cooler, filter, return to block) and 150 deg oil at the filter, you will agree he should not be trying to filter 150 deg 50 wt oil in any kind of volume. That cooler needs to be after the filter. High RPM/high oil flow volume and 150 deg 50 wt oil trying to go through a filter is not a good thing.
