I have a question I had a guy put a new stator on my motor about 3 weeks ago and when I took it out it would only get to 2000 rpm at wot I’m just curious could he have put the stator on the wrong holes we checked timing everything is advancing like it should but another thing that happened to was he was taking off the switch boxes he couldn’t get one of the screws because it stopped so he decided to cut a slot in the head so he could get it out and slipped and hit the switch box with the cutter didn’t go through but left a pretty bad cut in it I was wondering could that make it do what it is doing I would appreciate any feedback
Thank you

Check spark

I have good spark the boat on the water hose runs great will rev up to 6000 but as soon as you put a load on it that’s when it will only hit 2000

Need to test it in water as it will rev without a load to 6k on 3 cylinders

Was rect/reg plate grounded?

Was rect/reg plate grounded?

They set on a metal plate but they don’t have a ground wire coming out of them

I was going to replace them with the 6 wire regulator to see if that would work so I can ground them to motor to make sure it’s not a bad ground some where

Was rect/reg plate grounded?

Not sure how would I know if it is

 

[Faztbullet]

Make sure plate is grounded and rect/reg is rated for 20amp

Ok yea the new ones I ordered is but I didn’t see now ground wire for plate any where it is just bolted to the motor

do away with tha "bullet" connectors.. solder and heat shrink those connections...............

 

[Jeremy38870]

Ok I did away with bullet connections and know with new rectifier it will still jump up around 15 volts
