Proper Starting Procedure

[cigar_stub]

I have a 2002 Yamaha 115 HP outboard. While I have ordered a manual for the engine, I've not yet received it and the boat had no operators manual. My question involves proper starting technique or procedure. When I start the motor cold (85 degree ambient) it seems to take a long time to catch. Once started and warmed up, it restarts flawlessly with just a flick of the key. I'm convinced when starting cold, I'm just not doing it properly. Once in the water and the motor lowered, my process is as follows:

• Pump the gas line bulb until is feels resonably solid
• Turn the key and press it once momentarily (which I believe is the "choke")
• Turn the key to ingage the starter
• raise the throttle and hope it kicks in

It takes a long time and as I said, once started it runs perfectly. Am I not doing it correctly? Any advice would be great.

Re: Proper Starting Procedure

Are you sure you don't have to press in the key to keep the choke engaged? It is that way on my 125hp Force motor. When cold, keep the choke engaged till it kicks, then release it, and it should start right up. Another thing, some motors will start at idle, and some need a bit of throttle in neutral, if this is the case with yours, throttle up a little first before you hit the choke or key.

Re: Proper Starting Procedure

if it is indeed a 2002 motor then you have no choke-that's a fuel injected motor...you should just do the bulb and hit the key

Re: Proper Starting Procedure

I believe the motor has a 10/01 date code on it and if I understand Yamaha nomenclature correclty, it's considered a 2002. When the key is turned on and I press it in, I do hear something click under the cowling. Being as "uninformed" as I am, I don't know is clicking, only that I hear it.

I would think the manual I ordered (from Selco?) would detail this procedure. Does anyone who owns a Selco 2-250 HP Yamaha manual know if this topic is covered?

Re: Proper Starting Procedure

that would be your electric fuel pump cycling...once it gets to the required pressure it shuts off unless you start the motor...an '02 motor would have an"A" as the last letter in the model number

Yamaha 6E5 115XTRA

I believe this is the full model number. So if I understand you correctly, I just turn the key and perhaps give it some throttle while in neutral, correct?

Re: Proper Starting Procedure

you should not advance(or have to advance)a fuel injected motor...they have electric fuel pumps...try a fresh set of spark plugs for your hard start condition(cheapest way to start diagnosing)...also check condition of any fuel filters

Re: Proper Starting Procedure

Thanks for the help. Even though it runs nicely once started, I'd been considering putting in new spark plugs for no other reason than I'd know they are new and properly set. I'm not sure when they last replaced.

Re: Proper Starting Procedure

The cd shows that to be a carb motor with chokes. You should press the key in to engage the choke until the engine fires when cold starting. Also advance the fast idle until it starts and warms up.

Even though Yamaha started building EFI and HPDI motors several years ago, they also continued to build and sell the carb versions also. Its only been about a year since they were discontinued.

Re: Proper Starting Procedure

I know the problem, you need to have a beer first. I think the motor knows this and is trying to give you a hint by not starting right away. That always works for me, sit down have a beer, stare at it then for some reason the problem goes away.
