black max 150 trouble

OK REELAPEELIN WILL TAKE A LOOK AT THE OIL SITUATION BUT RIGHT NOW I HAVE AN IMMEDIATE PROBLEM MENTIONED IN THE BEGINNING OF THE POST, ANY SUGGESTIONS FOR THIS MOTOR PROBLEM COULD USE SOME HELP ???

[Skools Out]

actually it could still be your oil injection it may have some missing teeth on the gear and not be oiling proper and it could be making your motor run hot which would cause the pistons to swell and get tight in the cylinders which would make it run sluggish *and would make the compression start to fall as to also getting the block hot gets the electronics on the motor hot too which could inturn hurt them. may want to try putting some oil in the gas and run it some with both oil injection and mixed if the problem goes away with the oil added to the gas you'll know your oil injection isn't working correctly.

THANKS SKOOL THATS ONE THING TO LOOK AT. ACTUALLY THOUGH MOTOR RUNS LIKE A TOP WHEN I RUN IT A LONG TIME. A COUPLE OF RUNS I MAKE AT SPEED TO GET OUT ARE 20- 30 MINUTES. I THINK IF OILER WAS'NT WORKING I WOULD HAVE HURT THE MOTOR BAD ALREADY. IT HAD A STUMBLE WHEN STARTING OFF AND THEN WOULD RUN GOOD. AT SOME POINT LATER THAT STUMBLE WOULD TURN INTO BEING UNABLE TO ACCELERATE AT ALL

yeah it sounds just like a friends 1993 Merc 200 he had it was his oil injection gear he kept running it and he put around 30 hours oh it and then the compression got so low it wouldn't run anymore. If you run extra oil the oil will help raise your compression some too.

other than the problems you guys seen with the oil injection it does'nt ring any other bells as far as what it might be ???

willy...have the carbs been cleaned/rebuilt lately?...if not, sounds like it might be time...if you're not up to it, have a good outboard (Merc if you can find him) tech do it for ya...my old Evinrude went from runnin' like POOP to spinnin' like a TOP and w/the poor gas we're pumpin' thru these things these days it's easy to mess one up, specially if it's been sittin' for a while... ;)...

IS THAT WHAT IT WOULD COST TO HAVE CARBS DONE ??? ??? I DON'T THINK I CAN AFFORD THAT KNOW. MY FIRST BORN LEAVES FOR COLLEGE TOMMOROW, I'M SUCKING WIND FOR THE NEXT DECADE WITH THIS BILL. DOES IT MAKE SENSE THAT THE MOTOR WOULD RUN SO BEATIFUL ALL THE WAY UP AND DOWN THEN GO INTO GLICH MODE IF THE CARBS NEEDED SERVICE. I THOUGHT YOU WOULD FEEL THAT ALL THE TIME

[reelapeelin]

You can always get the manual and rebuild kits...not much $$ that way, plus you've learned something... ;) :D...I can't say for sure that mucked-up carbs are your problem, but if it's been a while or your boat DID sit for a year or so, it's sure a possibility... :)...have you CHECKED for water in the gas?...what year hull you pushin' w/that Blk Max?...if you haven't specificly checked for water, remove hose from motor, use the bulb and pump 1/2 cup or so into a CLEAR container, then tilt the container...if you see a liquid seperate to the bottom from the gas, that's water... ;)...

[willy]

OK RP I'LL CHECK FOR WATER, ITS A 92 MOTOR AND HULL ALL ORIGINAL. IF WATER WAS IN FUEL WOULD'NT IT BE RUNNING BAD ALL THE TIME ??? I'VE BEEN ON A GOOD NUMBER OF OUTBOARD BOATS AND THIS MOTOR SINGS WHEN THIS PROBLEM IS'NT HAPPENING, EVEN IDLES SMOOTH. JUST ALL OF A SUDDEN IT DECIDES OK I WON'T LET YOU GO ABOVE 1800 RPM AND IF YOU TRY I WILL STALL YOU. THEN I ALSO HAAVE THE MECHANIC SAYING THE FIRST TIME THAT I HAD NO SPARK ON TWO CYLINDERS ON SAME BANK ???

HEY WILLY, KNOW ANYBODY THAT RUNS A GAS STATION - THEY HAVE A PASTE THAT THE APPLY TO A MEASURING ROD THAT TURNS PURPLE IF THERE IS WATER IN THE TANK, YOU COULD WIPE SOME ON A YARDSTICK MAYBE AND DIP IT INTO THE TANK TO TELL, YOU'D PROBABLY HAVE TO PULL THE FUEL TANK SENDING UNIT TO GET ACCESS
