raymo Posted February 1, 2016 Report Share Posted February 1, 2016 Ive got an 01 2200V with a carbed VMAX 150 2 stroke on it...Ive owned the boat for about a year now, its been great to me and the family. Couple of issues here and there but nothing major. Until yesterday. We were fishing in the flat calm Atlantic about 5 miles out. Gorgeous day...no wind to speak of, temps in the mid 60s with cloud cover. Tons of bait everywhere and the Garmin is lit up. Then the alarm sounds...oil lights flashing on the gauge. Checked the reserve tank, 2/3 full...check the tank on the engine...at the low mark...and guess what...no oil on the boat...I know...ate up with the dumb***. :susel: Big thanks to SeaTow for the oil...I filled the little tank on the engine and she purred home...but now...need to get her back seaworthy. Help me troubleshoot this thing...are there inline filters between the two? where are they located? Is the pump something simple to troubleshoot or is this a shop only project? any pointers from the community are appreciated! Link to comment Share on other sites More sharing options...
Lap it Up Posted February 1, 2016 Report Share Posted February 1, 2016 will it fill the main tank under the cowl when you hit the backup switch? If it doesn't most likely your pump on the reserve tank in the boat has gone bad. It's easy to pull out. The pump is in a resessed hole on the back side of the reserve tank. Pull it and use jumper wires to see if it runs on 12 volts. The only inline filter is a small white one right near the 12volt pump. The harness and float switch are pretty stout and last a long time. I have changed the pump on multiple Yamahas. Link to comment Share on other sites More sharing options...
raymo Posted February 1, 2016 Author Report Share Posted February 1, 2016 had no idea of a backup switch...where is this switch located? Appreciate the info on the pump... Link to comment Share on other sites More sharing options...
Lap it Up Posted February 1, 2016 Report Share Posted February 1, 2016 Under the cowl in the vicinity of the main tank. Normally under the main tank or just to the right of it. You can also trick the system by pulling the float switch out and letting the float go to the bottom (alarm will go off when you do this). If neither of those start to fill it (it fills slowly) then pull the pump and jump it to a battery. Most likely pump died. Link to comment Share on other sites More sharing options...
Cajun4746 Posted February 1, 2016 Report Share Posted February 1, 2016 Also check your oil filters. There is a screen that can be replaced on the oil storage tank. I had a similar issue, and it turned out to simply need the screen cleaned. Link to comment Share on other sites More sharing options...
mdemott Posted February 1, 2016 Report Share Posted February 1, 2016 Can you convert to a premix on a VMAX? Link to comment Share on other sites More sharing options...
Lap it Up Posted February 1, 2016 Report Share Posted February 1, 2016 Vmax HPDI or carbed? Yamaha has a great oiling system with a great alarm and guardian mode. It really doesn't need to be byp***ed. I have a 1994 115 proV that has only needed one pump and one filter since new. But to answer the question, on a carbed VMAX it's fine to byp***. I wouldn't byp*** on an HPDI Link to comment Share on other sites More sharing options...
Mike45q Posted February 4, 2016 Report Share Posted February 4, 2016 At the risk of stating the obvious, I always carry and would recommend carrying some oil with you. I had he same problem and got home without Sea Tow. My mechanic pulled the oil tank and changed a filter. Original pump so i Need to think about preventive change since my boat is 13 years old Link to comment Share on other sites More sharing options...
large marge Posted February 4, 2016 Report Share Posted February 4, 2016 flipping the switch: when you flip that emergency switch - it grounds the blue wire to the pump - making the pump run.if the pump runs and transfers oil to the engine tank,the pump is good... usually,when this problem is encountered,it's a bad float switch. the filter wouldn't be a problem,if the oil flows,when the switch is flipped... on occasion - the small ribbon style harness,comming from the motor to the remote oil tank - these can break @ the motor connection point,under the bracket holding the harness in place... dumb question : does the trim indicator work ?

Fish_hook Posted February 4, 2016 Report Share Posted February 4, 2016 Mine was the wiring harness between the reserve tank and the motor.... I have a PDF I can email you of yamahas trouble shooting manual if you like... Link to comment Share on other sites More sharing options...

raymo Posted February 4, 2016 Author Report Share Posted February 4, 2016 thanks all for the replies... trust me...lesson learned on the oil...I have added that to a must have on all trips... I saw that small ribbon harness when I pulled the cap off the tank to fill it...I did not notice the switch at the time, but will check when I get the chance to work on it... and funny question about the trim indicator...it does not work...was bad when I bought the boat and have not found it to be a necessary gauge...I plan to fix it at some point as part of the process of making her perfect again...why do you ask?
