Hello all,<br /><br />I have a realy weird problem with my Yamaha. I don't know the exact details of the motor as I bought it second hand several years ago but it is a Yamaha 115HP V4.... I bought it in 93 and at that stage it was a couple of year old. I can post the serial number if that helps but for my issue it may be irrelevant anyway.<br /><br />The problem it has is that it will not start unless I follow a specific sequence... <br />I must first TRY to start (ie turn it over a few times) then I need to disconnect all wires from the (CD?) module .. these are marked coil1...coil4, ground, supply etc (I think 16 wires all up from memory). I then reconnect them all and it will them start and run beautifully for the day. I can stop & start whenever I feel like it. If however I don't start it for more than 15hrs I must go through the sequence again.<br /><br />A second general question I have is that I have NOT run the motor now for about 7 years ... the wife became pregnant with our first child, kids were too young etc etc ... we are now going to start using it again. I will take it in for a service before heading out on the water but I would like to run it myself first. I was going to put a little 2 stroke oil directly into each pot and of course drain all the old fuel ...but what else should I do before turning it over after such a long period?<br /><br />Thanks in advance for any replies coming ...

Re: Yamaha - Weird starting problem

take it to a pro. dont mess with it. have them test allthe electricals first. it willmost likely need a complete fuel system and cooling system overhaul. but first let them make sure your not going tohave any suprises. tellthem how long its been sitting and the problems you had before storing it.<br /> or buy the service manual and attempt it yourself. may as well correct all the problems made by extended storage before tearing something up.
