View Full Version : 91 PS 190 - Oil capacity/dipstick read??

I've heard that my 91 PS 190 has a capacity of 5 quarts...no problem draining all 5 (and slightly more) out...did it overnight. Now however, I've only added 3 quarts, and the dipstick reads over-full no matter how many times I check it (and after running for a few minutes to fill the filter). Does anyone else have a false dipstick reading? Should I definitely add all 5? Is it possible the dipstick is the wrong one? Looks right, labeled "Ford" (I've got the 351 natural to this year)...thoughts from you experts??

Welcome to the board.

For future reference make you might want to fill the oil fliter with oil before you crank it to avoid a dry start.

Somewhere I read that there were some cases where the wrong dipstick was in the engine.

I am working on geezer memory but,

My 90 tristar was like that.. Dealer told me just put 4 1/2 qts in and run it... No compensation for the engine being tilted at the dipstick, so incorrect read... At least thats what I remember.

My 94 Maristar had an LT1 dipstick in it.. 6 qt. and I needed a 5 qt. Still have it around here somewhere.. Anyone need it?????

Did the dip stick read right before? It sounds like a tilting problem?

My '91 holds 4.5 quarts.

Welcome, Kevin. Some of the prostars of that era came with the wrong dipstick. Get the part number off yours and call your dealer to verify that it is the right one. Also, from my conversations with a dealer, there is both a long and a short filter that will work on the 351W. The long one will hold a bit more oil. If you do a search for dipstick, I recall I posted the part number that was the correct dipstick for my 93 PS 205 w/ 351 HO.

Direct quote off of the Discount Inboard Marine (DIM) FAQ:

"OIL CAPACITY, FORD 351, INDMAR OR PCM
The pan holds 4 qts. Filter 3/4 to 1 qt
* Put in 4 qts and run engine to fill the filter. Then add just enough oil to bring it up to 'Full' on the dipstick.

Know this: Less oil is more horse power because you are not pushing all that oil around."

I have the same exact problem with my stick reading high. I usually just go with 4 to be safe.

One thing that I have noticed on my dipstick is the backside of the stick gives a much more accurate read. The front side always seems to smear the oil up the stick and give a high reading. On the backside I get a better line. I have been using the Napa Gold #1515 filter and run just under 4 1/2 quarts and the backside of the stick reads right at full the front side looks overfull and smeared.

As lake pirate suggested, it still sounds like a good idea to fill the filter about 3/4 full to avoid dry starting it.

You guys are awesome - nothing beats this board. Sounds like I have a few options to try, but I'm definitely in the right range. I'll try the 'backside' read method and calling the dealership. Then back to the lake! :steering:

Kevin, just for your ease of reference, the correct dip stick for my 351 HO was Part Number D5UE 6750 AF Ford M

THANKS again - you guys have helped me through installing a stereo, and now decoding my oil level. I had the right dipstick (thanks for the Part #), and by checking the back of the dipstick, I was able to see the oil level much easier. What would have taken me a week or more to figure out, I figured out in 12 hours. Took just under 4 quarts once the filter was full...exactly as almost all of you had expected.

Someone can tell me where I can find the horse power of my engine?

I always put a carpenters level on the floor of the boat and jack the trailer tounge up or down till the floor is level as it would be in the water. I always keep a quart in the boat so when on the water when I check it again I can top off if neccesary.

Might want to get a copy of your manual from here:

http://www.mastercraft.com/index.php?znfAction=Manual

Typically they list HP by engine type....otherwise, what engine is in your boat?

I was going to say, it is best to check the oil with the boat in the water. Then it is at the proper angle. I believe the manual also says this.

Once you get it right, the next time you change your oil, measure how much you remove, then put the same amount back in.

I called indmar directly gave the serial number got the real info. The dealer who sold me the boat said it was the indmar 5.7 assault motor 330 h.p. When in fact Indmar did not build that motor for M.C. My son was crushed when he found out that we didn't have the BIG motor.

good luck they we're very helpful
