Thank everyone who looks and advises me with this
I have a 18' 1997 Manta Ray Bow Rider with a 96 Mercruiser 3.0 and an Alpha One Drive...
At the beginning of this season I rebuilt the carb and after that the motor started dieseling and I talked to a few boating people and they suggested that the timing was off so, this past Thursday I adjusted the timing and got the motor running good on the hose and it dropped the RPM's and I got them down to about 700. Now move forward to Saturday we took the boat out and i put it in the water and I wouldn't stay running cause the RPM's were to Low. Also My full throttle is only 3500 RPM's and I cant get anymore out of the engine.
Prier to adjusting the timing I was getting max RPM of 4800 and I have a 19 degree prop.
I followed the directions in the shop manual and put the timing at 1 btdc and when look at the timing after removing the jumpers I cant tell where the timing is but every so often it shows at 1 btdc.
Any advise would be great
Thanks Chris
