Default What to use?

I have an 5.0l carb engine in my 01 Maxum 3000 scr that has some issues. It will run for about 10 seconds then quit. I have had enough of boating this year and the boat gets hauled out next wednesday. I am getting it looked at in the spring. I do my winterizing myself. when its on the hard.

I am wondering what I could use to heat up the oil in this engine so its not a pain to do. I have the oil draining tube that I stick out the bilge drain hole that is attached to the bottom of the oil pan.

Thanks

Roger

Try an electric dipstick heater.

Regarding the engine I think yours has electric fuel pump and the oil pressure switch that powers it may be bad. Pump gets power from the starter when cranking then the oil pressure switch closes when engine starts and provides power. No power the engine runs out of fuel.

Thanks Mike. Should I try to match the length of the electric dipstick heater to the oil stick?

I'm so sick of boating because of what has happen to the boat in the last 2 months with the shift cable and other things I'll wait another year.

Roger yes you want it no shorter than the existing dipstick, it can be longer.

You should be able to drain it through the drain plug hose, but at ambient air temperature it will take several hours. I've successfully pumped unheated engine oil as well. getting an initial vacuum takes a while and it is also a slower process, but not impossible.

I had to pump a qt of diesel oil through the dipstick with a mini hand pump with oil at 50 degrees last spring. It took me about 1 hour, but was possible. I certainly wouldn't want to do all 11 qts.

Thanks Shrew! I'm going to NAPA to buy a dipstick heater.

Hey Mike....about the your take on what might be wrong....are saying to change the oil sending unit and see if the works?

Nevermind Mike LOL...I got the service manual out and looked it up. Should have done first.

Not the oil sending unit but the oil pressure switch which is located where the oil filter or adapter connects to the block. Rear portside
