2 stroke
Submitted by Shane O on Mon, 2012-09-17 12:43
question about 2 stroke outboards. Mine runs ok, just a bit slugish getting up to speed. when the throttle is over half way it gets up the plane quickly but it does not like going slow. does not die or anything just doesnt seem to like it much ????

ive got a 2008 115 optimax and i love it, though i know exactly what you mean
mine doesnt like going very slow either, it gets quieter as i increase the throttle

Same
Mine runs better the quicker I go, so I go quick.

I have a 115 Yamaha
I have a 115 Yamaha saltwater series and found between slow runs I give it a good run at higher rpm it smothers right out they need a good run to clear, normally give it a good run before going back to the ramp, have found it to start and run better next time out

What brand do you have
Some switch off cylinders when going slow which may seem sluggish until speed is up eg mercury optmax

I have the same issue here,
I have the same issue here, I've been told it might pay changing propellor sizes or at least talking to someone about it, I run a 115 Johnson Ocean Runner but by the looks of things it seems to be the norm.

35hp 3cyl Johnson
Yeh mines the same when just idling around I think it's because of the loop charged carbies

Run fuel dry
Does everyone with a 2 stroke run fuel dry when flushing the motor? Does this do damage to the motor..

I wouldnt suggest it. Carbie
I wouldnt suggest it. Carbie seals etc can dry out depending on model. Also the last couple of fires would be lean as well which could mean insufficent lubrication as well as other issues incountered running lean.
Maybe check the user manual?

The Manual for my Yamaha
The Manual for my Yamaha Salwater Series II recommends it. I believe its to stop oil settling in the bowl.

just remember that 2 stroke
just remember that 2 stroke fuel only last for about 3 months at the most when mixed, and yes i do run my motor dry because shit fuel mix in the crabies is not good, i put fuel stabiliser in my fuel so it stays fresh for 12 monthes, and 2 stroke are meant to rev hi, so the harder u use it the better, never had any issues with my 25hp merc, and i thrash the hell out of it, just make sure the fuel mix is correct and u should be sweet

on this subject..
.. do you find on the smaller 2 strokes - mine is a 25 Johnson, that they really don't idle well in gear, like when drifting and just putting in gear to move or chage direction? Mine cuts out often in gear, but it will idle all day long, but idles quite rough - maybe it is set too slow in the idle?
