THE BASS COLLEGE

my  1995 75hp mercury lost spark on all 3 holes dont want to fix so im in the market for a used outboard 75hp-90hp 1998 or newer yamaha or mercurybut i donot have more than $3500 to play with. also im from hagerstown m.d. donot want to go more than 3hours drive for one so if you have one for sale let me now thanks

The mid 90's Merc's had a lot of problems with faulty kill switches. If all 3 cylinders went at the same time it could be an easy/cheap fix. A simple volt meter can tell if the switch is completing the circuit, or you could simply by-pass the switch all together (for testing purposes only obviously)

how do you go about bypassing the kill switch is that the black and yellow or the orange wire thanks for the info

I think our member here Jimbones is a mechanic also and knows a bit about them. I cant remeber but there are several others here also who know a good deal about them so I hope they see it and respond.

If not them, ive got a friend who im fishing a tournament out of his boat sunday who is a mechanic also.

man i cant wait for daylight to test the kill/shift switch o yea wen it killd over i was 8 miles from the ramp at big slake water on the upper potomac and the guy that towed me back hes water pump went out from over working it half way back let me just say that was fun but i did have 10lbs of smallmouth. to all that respon thanks for the help

well i by-passd the kill switch by disconnecting the black and yellow wire in the control harness but still nothing so its deeper than that

well if its the stater the one for my yearand model is obsolete

Did you disconnect the wires from the switch and connect them together or just disconnect them from the switch?

Was the motor still turning over fine when it lost spark?

yea it turnd over fine till the bat went deid witch it was low from the get go but the bat is charged now and the motor turns realy good just like it always have as for that black and yellow wire from the cdi to the controls i just unpluged it but i did see another black and yellow wire from the cdi was i soposed to plug in to this wire

Disconnect the wires at the switch and connect them together to complete the circuit. that should trick the motor into thinking the kill switch is hooked up and in the run position. If that doesn't work then maybe one of the mechanics here would be close enough to take a look at it for you

well so i jumpd over the kill switch first and then the shift kill switch i still dont have spark i even went to the cdielectronics  troublshooting guide still nothing so the next step is the ignition itsself like cdipack,stator,triger,coil's that kind of stuf and thats past my relm of fixing things so its of to brooks marine so they can have a look o yea cop. is 116,120,117psi all turns freely and plugs are brand new. i hope this problem dose not run my bill up to $1000 well ther goes that power ploe and hds-5 on bow and consol or that jack plate i wanted to get o well

If there is a plug on engine that runs to the helm unplug it.Next jump across the solenoid or starter to spin the engine and check for spark.

do any of you guys live near him , maybe somebody can help him out in person if there close

I am fairly near, him about 25-30 minutes, not sure if thats much help, he could take it into my friend greg is he wants it fixed instead of a new motor.

im 15 minutes from him but have little knolage of the mechanics of a merc.

well i made a call to my good freind brook from brooks marine told hem what was going on and the test'sthat i have don so he told me its my stater is at falt it has glued in magnetsthat come loose so the flywheel needs pulld to inspect he did tell me that it will be $500 to600 to fix that good news its not $1000or more but its all good because i well be on the back of a jetboat the rest of the year on the upper susqahana so i have time to save up money to fix

Cool Glad to hear that. I hope to see some nice bass from you up there soon. Good Luck. 

steve do you have a jet

that would be some good video of 4lbs smallmouth
