engine has bump when using tilt trim

I have an Evinrude 200, model  E200dhlsch.  it is now in the shop try to diagnose problem.  What is  happening is when I use my tlt trim switch there is a slight  pump in the engine.  It only does it when I start to trim up and  not down.  They have been working with brp tech to figure out but yet have not come up with a solution.  My tech says that the engine is cutting out when the **bleep** trim is  used.  engine does not shut off just a short interruption.  has anyone experienced this?  It has about 900 hrs on it but it does run good.

Re: engine has bump when using tilt trim

Trim pump motor will pull a lot more current going up rather than down.  Increased current demand is placing greater demand on engine alternator output.

 

Have mechanic verify 55V remains stable when trimming down.  Could be pulling down 55V because battery is unable to supply current required.  Look for corroded/poor connections between battery and engine.  Battery with bad cell, etc.

Re: engine has bump when using tilt trim

checked the stator, as recommended by evinrude, capacitor also.  both  are fine and functioning well.  next step is to check the harness for the tilt trim.  it is the original harness from the 2000 ficht that was on the boat.  I repowered in 2008 with this current engine.  can this be the cause?????????

Re: engine has bump when using tilt trim

A weak or too small capacity battery plus poor cable connections is often the problem giving the symptoms that you described.  Sometimes with a voltmeter both on the motor and on the battery will show the voltage drop when the trim UP is activated. The current draw on the trim motor under load should be monitored and compared to the factory specs.

Re: engine has bump when using tilt trim

we believe we found the problem.  It appears to have been a bad ground in  the tilt trim harness.  They got that fixed and had it lake tested and working fine.  sure hope that does it.  Took awhile to locate problem.  thanks for your all assistance, I believe by relaying this info to them help to diagnose situation a lot quicker.
