Title: OILING QUESTION
Post by: the.perv on May 07, 2012, 04:37:09 PM
I know I either asked this before, or I have seen this on here before (ive slept since then). On a motor that will turn 4500rpms what type of oil pump should I use?

A. Stock or
B. High vol

I run the hell out of my boat (like wide open for 5-10 mins at a time, is this bad?)& only have a 5qt pan (or at least thats what im guessing) it is a stock BBF pan, Im not sure if staying on it constantly will pull all the oil from the pan (until its starving for oil), anyones $.02 would help. Something else I pondered on was getting a KAASE oil pump because they are alot more durable but I am unsure if he makes a standard volume pump or not.

Anyhow any info would help, trying to get it back together by memorial day weekend. Thanks- the.perv

larger pan is *always* better.  a million dollar high pressure or high volume pump isnt gonna do crap when theres no oil in the pan.

So whats your suggestion to me keeping a stock pan? They came stock with them you would think they are kind of ok. I just dont have the time to change my motor mount system in order to get a larger pan in there. I guess I could use my father in laws boat for the weekend (stupid fishing boats)& address this issue after the holiday.

The Kaase pump is a standard volume pump. Based on the way you run your jet boat ("wide open for 5-10 mins at a time"), I would strongly recommend adding an HV pump when you install the jet boat pan. (I almost always recommend HV pumps for 460 powered jet boats.) There's probably no need to mess with your engine program now if it's working for the time being...but do keep an eye on your oil pressure gauge.

You dont think a high vol pump will hurt with a stock front sump 460 5qt
pan?

I did not recommend an HV pump with your stock front sump oil pan for several reasons and it's way too lengthy for me to type why, but it has to do with 1) the various front sump oil pump options, and, 2) the two possible oil pans you have on your engine.  Better to wait until you buy a jet boat pan and then just get an M84DHV oil pump at the same time (M84DHV will not work with your front sump pan, get it now?). When you order your jet boat pan, BE SURE to specify the pickup tube that works with the M84DHV rear sump truck pump.

Any further questions please call,

I would also use a accumulator they work well and save starvation issues.

It accumulates....BWAHAHAHA ;D

Basically it is a small tank that has an air pressurized diaphragm in it and keeps the oil pressurized if engine generated pressure is lost for a brief moment.

They also make a great pre-luber. :thumbup: :thumbup: :thumbup:

there a basic band aid. they are to keep one from lossing oil pressure for a brief moment. the prob is if you are not paying attention . and shut the motor down it wont matter if you have one or not. keep that in mind.

5 quarts of oil will get HOT in a hurry at WOT.  I'd watch my temp climb and pressure drop with a 12qt pan on a 500ish hp BBC....in less than 8 miles...oil pressure was....well, not good.  Run a good oil like Total
Quartz racing 15/50 that can handle temps, at the very least.  Group 3 base stocks can't hang.

Group 3 base stocks???

Good info thanks guys. Well im gonna assume thats what happened to me then, I ran it hard (Wide "F" Open---WFO) for a good 5-10 mins and the oil got hot and cooked the rod bearings.

So, invest in a accusump? Or invest in a oil temp gauge so my retarded a$$ doesnt do this again?  :banghead:

Also anyone know if a canton marine pan 7.75" deep will clear a stock motor mount setup with the cross member? & if not I am going to find out this weekend anyway, im gonna drop the bare block in w/the bell housing and measure, if it does not clear I am thinking of building my own crossmember to clear the pan & cutting out the stock one? Has anyone done this before or am I just that redneck lol...
