I have a 2007 evenrude 90hp etech that stopped charging my starting battery and left me out stranded in lake erie, after jumping it and getting back to the launch,I brought the battery in and got it load tested, the battery tested good. so I took the boat in to a boat mechanic and they are saying that it is a bad circuit on my computer so I need a whole new computer for it. the cost sounds like it will be around $1500-2000. so the first questian I have is: is that a resonable price? and second is when I get this fixed what are the chances it does this again? If its something I have to worry about forever, ill sell it. also what causes these to fail? he said there will be a one year warrenty on it after but seems like I should get a longer warrenty. thanks in advance for your help im just really frustrated since i got the boat two years ago and it only has 84 hours on it.
The price sounds about right if that includes the labour to fit & program the new EMM. The chances of it failing again would be very slim. The mechanic should also check all electrical connections including battery terminals. NO WING NUTS as this can cause electrical failures such as yours. The 1 year warranty on spare parts is standard for all brands.
I have an 08 115 it is junk. Unload yours on someone if you can. I was offered 2000 dollars trade in on mine and it cost more than that to fix it. Eery time someone complains about an emm going bad they make up an excuse why its the owners fault for letting your battery get weak or you didn't check your terminals and you had wing nuts so its on you. Give me a break with the excuses no other outboards have this kind of trouble and the cost is less than half to repair.
