timing v6 evi rude

[mr gibbs2]

1990 200 hp evinrude . replaced power pack, timer base , sator,with digital cdi units ,and replaced flywheel . Runs as good as it always had before power pack went south , but starts at the flip of the key . top rpm is 5300 no hesitation but timing is off about 8 degrees with a test wheel in the water . should i mess with it or leave it alone ? the timer base is flush against rubber stop at 5300 rpm would backing off the the rubber stop, letting the timer base move more toward the front of the motor give it more rpm ,and make it run better .

Anytime you replace a timer base you need to re-time the engine. I believe CDI gives you a way to do this with a procedure on the digital setup that is pretty easy. Check with them about how to go about it.

called cdi they said you can advance the timing to factory specs as per the timing light , and you would achieve higher rpm. leaving it the way it is would not harm the motor ? any thoughts ?

Well that's a pretty sorry answer in my opinion? The timing needs to be checked when those items have been changed. Any increase in performance/fuel economy would be welcomed. Using a timing light you can use the Joe Reeves method. It is on this site somewhere? Hopefully another person will point it out.

Anyway advance the timing 4 degrees close to factory specs , ran the motor with a different prop ran at high speed ,sounded better , went from a 15x17 to a 14 1/4 x19 ,achieved a higher rpm 5500 . i think i will going to go 2 more degrees more to make the full advance factory specs . sitting at the dock with a test prop on at 5000 rpm is a bit much ,getting looks / i cant believe it was so far out of adjustment .
