89 200 rude cuts out high RPMs

[kline]

last weekend i unloaded my boat and left it idling at the dock while i parked the truck, to let it warm up a little.at an idle towards the end of the no wake zone a solid horn sounded so i thought it was hot. i pulled the cover and i could touch the heads all day long. i figure its the low fuel warning so i pumped the ball and started it. a few seconds later the horn quit. i took off hit about 4500RPMS and it was like the key turns on and off every few seconds ,if you accel slow it will get up around 5000 . i looked around at hoses and the VRO and there wasnt any kinks or leaks that i could tell. i know its bad if its running lean but i had to get the fill for what it was doing. its an 89 200 evinrude,problem sure fills like an ignition problem.any ideas THANKS

Re: 89 200 rude cuts out high RPMs

This is just a guess ,but one of the first things that I would eliminate is to make sure that the safety lanyard switch is not the monkey.Do you have the side mount type controls with the rubber cap that postions over the lanyard switch?if so ,those rubber caps get stretched out after a while and allow the button to come out and intermittedly kill the ignition.<br /><br />As far as the alarm goes,the engine either overheated or the temp sensor or alarm circuit is acting up.Since you were traveling at a slow speed just before the alarm sounded ,it is indicative of a wearing out waterpump that will not deliver full flow at low rpms,or a momentarily stuck water bypass valve or poppet valve.<br /><br />Also insure that the fuel bulb is not colapsing during the failed run as would be caused from a faulty bulb or other restriction upstream toward the fuel tank.

thanks for the reply , my impeller and housing is new. i was kinda thinking it might need a new fuel pump.my kill switch is a fork type prong that holds a knob out i messed with that while running and got no problems. if not for the low fuel horn id probly be looking at spark related forums. as for the bypass or poppet valve i dont guess i dont know what that is.termostat maybe?if not learn me about them there dills.THANKS

Re: 89 200 rude cuts out high RPMs

I wasn't sure whether an 89 model had the fuel restriction warning or not from the vro harness.If so look for a fuel resriction from the primer bulb upstream to the tank.<br /><br />Two things you could have checked when the engine would not get on step while running is to #1 pump the primer bulb to see if it would pickup ,and #2 intermittedly bump the key switch primer button to see if the engine would react.If #1 makes it pickup,the fuel pump is likely the problem.If #2 makes it react and pickup,fouled carburetors may be the issue.<br /><br />In any case the alarm may or may not be related to the performance issue ,but it was either an overtemp warnining or fuel restriction warning from vro as would both be indicated by the constant steady alarm tone.

Re: 89 200 rude cuts out high RPMs

I have an 88 200 rude been through the over temp<br />alarms/bad temp switch. But when my horn sounds continuous im limited to 2500 rpm till the switch opens and I shut off and restart.<br /><br />I have a clip lanyard and the prong was slightly bent once and my engine cut out intermmitantly till i realized what was happening but no alarms sounded.

Kline <br />Had the OMC bible open working on one of my issues came across the warning horns<br />Mind you these are from the CE Loop v series manual <br /><br />Overheat: continuous tone<br />No Oil : continuous short pulse<br />Low Oil : short pule every 20 seconds<br />Fuel Restriction: continuous tone at or near full throttle<br /><br />Hey i just remembered i had a simular problem few years ago. a part in the primer bulb broke and would float around for awile until it plugged the draw side. took me 2 trips out to find that one.<br /><br />hope it helps

thanks again for info , i did push the key in while running it didnt seem to have any afect but its impossible to do when it cuts out because it happens so fast . i guess i should have just held the key in and tried to let it wrapp out but i didnt think about that. i was by my self and the boat would still run almost 50 mph so i didnt jump back there and pump the ball. i could see the pump ball and it didnt seem to be collapsing. thanks again

Re: 89 200 rude cuts out high RPMs

Kline,You may be chasing an intermittent ignition related issue .These can be a real bear to track down at times as many times the components will seem to check out fine while running at low speeds on the hose.See if you can use a mirror and flashlite to do a visual inspection of the stator windings looking for any signs of goooey residue that would indicate a winding failure.Removal of the flywheel will reveal a better look.<br /><br />You could also run the engine on the hose and heat the area around the powerpack , ignition coils, and stator windings with a hair dryer to simulate a warm component failure symptom.Also check to insure that the timer base under the flywheel will move smoothly all the way to its stop adjuster when the throttle is advanced.

Re: 89 200 rude cuts out high RPMs

thanks for the reply,i dont mind working on boat motors, but an ignition is a diferent story .im tring to hang on to this fuel thing,but knowing my luck ill be out there with a hair dryer before you know it.im thinking ill put a fuel pressure guage on it and see what kind of reading i get. im not to sure but i think i need at least 3 psi at 800rpms in gear. correct me if im wrong THANKS AGAIN

Re: 89 200 rude cuts out high RPMs

Have someone drive the boat while you pump the fuel bulb. If problem goes away rebuild your VRO pump. If this is not the problem look closer at the ignition. This is the right way to diagnose the problem rather than sitting in the shop. In literally 2 minutes, you can eliminate your VRO as the culprit. This wont be a hard fix you just have to make sure you replace the right part. Keep us posted.<br /><br />James
