Bogging problems

[Jules2381]

I have a 1994 mariner 2 stroke 4 cylinder o/b. When I first launch and take off it runs maybe 1/2 throttle for about 200 yards then it opens up and will not do this again all day. The next time I use it, it does the same thing. Carburetor so were cleaned,have a new power pack and trigger

What horsepower ?----Why those new expensive parts ?------Thermostat installed and working properly ?----Do you give the motor some time to warm up ?

 

[Jules2381]

40 hp and yes to warm u, it idles fine

 

[Jules2381]

The other part were due to firing problems and done by merc mechanic

 

[racerone]

Open the low speed mixture needles a 1/4 turn and test run.----If still bogging open another 1/4 turn.

 

[Jules2381]

Thanks will try next time.

 

[Jules2381]

Just seems strange it does it at first then not again the whole day

I had the same issue with my motor bogging down.. I cleaned the crab's had them adjusted, all that... but it still bogged down..but I was told by every outboard mechanic that it was the crab's not cleaned correctly... so I took the crab's to a shop and they put the crab's in a shaker machine. I was told that the small ports in the crab's were closed.... just something to think about..
