Yamaha 115 2-stroke Drama

[gford001]

Hi,
I have a 93 model 115 Yammy 2 stroke. Took the boat out today and had no dramas. Stopped and started half a dozen times with no problems. Had it about 6 months, never had a problem with it (the motor anyway, fiddly bits with the boat all the time), and been recently serviced. Loaded it onto the trailer and took it home. Went to wash the motor out and there's no electricity to it.
Won't start, can't tilt, nothing. Tried other electronics and they're all running fine so the batteries are ok (tried 1, 2 and both).
Is there something simple to check, like a fuse somewhere?
Don't want to go pulling everything apart or taking it to the mechanic if there is likely an easy fix to be had.

Cheers
Glen

Did you check the dead man switch ?

[Tickleish]

Yeah check dead man switch and just because their is enough power to run electronics does not necessarily mean they have the guts to crank the outboard so I would be testing the batteries properly.

[gford001]

Yeah checked dead man switch (not activated) and had my neighbor come and double check batteries....
Maybe dead man switch is faulty. Will have a look at that tomorrow.
If that's off can tilt/trim work or nothing at all?

Is it just in gear a tiny bit? Seen that before...

[Muddy Toes]

Battery leads making a good connection?

Yeah mine can be fiddly, had a couple of scares out on the water with the boat not starting. Usually a bit of a jiggle sorts it out, but not this time.
Doesn't explain no tilt/trim though..... It seems to be getting no power to the motor at all.
Seems weird that it has been fine up until now, but nothing at all when I get home.....

Just redone the battery connections, they were dodgy as hell, but all new terminals throughout. Will take them off tomorrow and make sure the connection is good anyway, just to eliminate.

Dead man switch won't stop it cranking.
Check the connection s on the 12Both switch too.

Will check that too. Cheers.

Mate it will be something simple. Where are you based and where did you get the engine from?

Mango Hill. The motor came on my Caribbean Half Cabin that I bought at the start of the year. Nice old boat, needed a tidy up and Ironing out some of these little problems.....

I wondered if it was mine. I had a 92/93 model until I traded to a 99/2000 model a while back. The 92 are an excellent motor mate. It was pre-saltwater series, but that didnt seem to stop it from long service life. When you sort out the electricity issue, give some consideration to getting in and greasing the timing advance unit under the flywheel...mine got gummed up. They are pretty bulletproof though.

Main Fuse?

Where's that? Havent had time to have a poke at it today, all lights/electronics are working, but nothing on the motor (tilt/trim, starter).

[honda900]

there will be one on it, this is a later model than yours but it may help.

Cheers mate, ill check it out tomorrow. Hopefully have time, damn cars on its last legs too, have to go trade it in while its still worth something. :-)

Well, got it sorted, was a 10amp fuse inside the motor. Only drama is i started it up, flushed it then turned it off. No power again. Assuming its done the fuse again.....
Might replace with a 15amp and see how i go.
At least if it happens now on the water i can get it sorted quick enough.

[Crunchy]

If the 15amp blows maybe replace with a bolt cut to the right length

if it.s starting to blow fuses all of a sudden, there has to be a reason.
maybe first thing to check is when you turn it off, check the fuse before you try and restart it again. if it's ok, then that would rule out a problem in the starting circuit?

The fuse is there for a reason! I wouldn't go replacing the fuse with a bolt cause you could end up creating more problems later on?

[Spaniard_King]

The main fuse on the engine is normally a 20 amp fuse.. if it's blowing you have a fault in the ignition power circuit.... normally this fault occurs when someone wires an accessory of some sort in the ignition power circuit under the dash . It could also be the starter solenoid but this is a rarety

Good idea, I will have a look at this tomorrow.
Pretty sure it had a 10 amp in it, maybe it is meant to be 20, will check the manual and try a 20 as well.
Thanks for the help guys :)

I think he was joking Skipper.

Yeh sometimes I can't help myself, but to be a little more helpful I looked in the attached manual and the fuse should be 20A as Garry said so perhaps someone has put a 10A in there to get by or in error. Hopefully that's all it is.

Sorted. The old fuse had obviously been in there a long time and was stuck pretty bad ( I had to dig it out in pieces). There was more crap and corrosion in there so the new fuse connection was pretty sketchy. Have cleaned more out and will replace the fuse holder when I get a chance. Working now, but if I don't replace it I think it may cause more dramas later.
