2001 90 HP Merc ELPTO
I have a 2001 90hp ELPTO mercury outboard on a 2001 Ranger R61. The motor tends to have problems starting and ideling; however once the motor is in gear the motor runs great it will get up on plane and run at its 5500 rpm projected max no problem. Can anyone please advise to what might be causing these minor problems with the starting and ideling.
Is the problem primarily related to COLD STARTS (in other words, it starts and idles better once warm)?
Pumping primer bulb firm before EVERY engine start?
For COLD starts:
-Set engine trim at LEVEL TRIM
-Pump primer bulb FIRM
-Push key IN for 10 seconds (one thousand one, one thousand two.... you get the drift)
-Turn key to START. If engine begins to sputter out, "bump" the key in (push) for a split second until the engine runs on it's own.
You should NOT need to apply any throttle for starting, if everything is properly set up.
On a separate note, be sure to read through the following post, and ensure that ALL recommended items have been addressed on your Boat/Engine:
One other item we're seeing is that the "tuning" used on these engines (when manufactured or originally set up) was well suited to the fuels used AT THAT TIME.
Today's fuels simply do not burn the same. In many cases, each idle air screw may need to be opened SLIGHTLY (usually 1/4 turn counter-clockwise- be PRECISE here) works quite well.
ALL idle air screws must be set the same... very critical also. :wink:
I had the same prob with my 03 90 elpto tightned up my fuel line hose clamps cured the prob. Still wrkn on my other problems .
Thank you for the advise;however, the problem is not only when cold starting. It is all the time, especially when cold starting, the motor will run fine on plane idel for a few seconds once off plane then dies. I have done all the basics as far as changing plugs, adjusting the idle screw, changing the fuel water seperator, the fuel filter and even cleaned the carbs. What is strange about the motor is as long as it is in gear it will run with out any problems once out of gear it always dies.
Were the REEDS removed and inspected for broken, chipped, or excessive-standoff reed petals?
COMPLETE Sync-n-Link proceedure done (this is MANDATORY if carbs are removed for ANY reason)?
I believe so the work was done a by a Mercury certified technician.
I would hope so.... but I believe it would be worth checking into (and verifying by inspection). :wink:
