I replaced the powerpack about a month ago. I have used the boat a few times since then and she starts and runs great.

went out yesterday and after motoring at wot to a good sitting spot I turned off the key. Boat keeps Running. Pull the Lanyard and motor keeps running. I turned the key on and choked it and it died. Started it up again and same thing. I finished off the day fine and just had to choke her off.

Got home and pulled everything and started testing. Ignition switch and killcircuit are fine...narrowed it down to the power pack has an open in the shut off circuit.

I don't have another $100 to throw at another powerpack, this was replaced already for a WOT intermittent issue so this is a new problem. There are no refunds or exchanges on electrical parts from the internet :mad:

The Black wire with a yellow stripe should kill the motor when grounded to a known good ground...it does not. The kill circuit from the box tests good. my grounds are good...

I am convinced it is the powerpack stop circuit....

However I was reading a post here where another poster had solved this issue by removing the powerpack ground wire and the motor would die.

So I brought out some test leads and rewired the ground wire to the pack with my test clips and started the motor....removed the clip (circuit) and the motor died. Replaced and it started right up again....

I was wondering if this would damage more or faster the powerpack to wire it in this fashion...I was actually thinking about running a relay to that ground so that when power was cut with the key then the motor would lose ground and die. Then I won't have to hack anything up, and can replace the power pack later after the season.

Thoughts? or danger will robinson?

I'm just trying to get through the rest of this season...and should I be worried the pack will next fail and give me a no start? or just luck of the draw with a bad connection on the yellow/black wire within the pack that I cannot see/fix

I have read your post several times and quite figure out your problem, I looked at a parts breakdown of an 1989 48hp and don't see a power pack, could you post your model number?

Those motors have the powerpack/pickup assembly that is under the flywheel. I know the wires coming from these packs see a fair amount of strain from the rotation of the ignition plate. I'm wondering if the yellow/black wire hasn't possibly broken internally from the motion ofthe plate. You may want to check the yellow/black wire with an Ohmeter and see if it has possibly gone open.

I won't be able to pull the flywheel (again) until later on....meanwhile we took it out again today for about 2 hours and it ran fine....i never shut it off cause we were just cruising a combo of WOT and then some slow 1500-1900 rpm cruising while we chatted and had a cold one.

Got back to the ramp and choked it off and went home. so it was a god day

meanwhile, I am eventually going to pull the flywheel when i get time.

but my question for the gurus is will pulling ground from the powerpack via a relay damage the powerpack further and faster....again I saw a post where someone wired a motor this way with a switch and it worked, but he never updated to whether it fried anything later :)

glad this time it's "broke running" then "BrokeDown" :facepalm:

OR.

Would I be best to leave it alone this season and just choke to kill it? With time constraints etc I'll be lucky if I get 4-5 more uses this season anyway....

if it is a CDI power pack, they give a 1 year warranty

If you really go back in time there were some mtrs that you had to choke to stop. Just beware your kill circuit won't function.

True...And since we don't use the boat for much more than motoring to a quiet spot and sitting I am not as concerned about the kill switch as if say I had a boat full of folks and kids skiing tubing etc....then I would not be as cavalier about it.

I need to look in the shop and see if I can find the paperwork for the darn Powerpack..as well as the email I recieved about it. I don't order much from online, actually had a friend do it for me. so I will check what their rules are....I hate pulling the flywheel yet again....PITA

so it seems the consensus is to not fool with the CDI ground/relay rig? And to just choke to stop as a temporary means until I figure out replacing the powerpack hopefully under warranty

this sucks cause it runs better than ever, just cant turn it off :eek:

As said previously, it could just be a broken wire under the flywheel where the wires flex. If it was my boat I'd just run it till end of season and then fix it. BUT, Be Careful. Those ignition systems did Suck tho'.

In the long run you will be better off changing out your system to a normal external power pack. Get a replacement armature plate from a junk yard to keep the prices down.

This would be great. Is there a write up somewhere on doing this? Or keywords to try and search? For the moment I will choke it.....again since I don't ski or tube or party barge a bunch of people I should be fine....


Thanks

Just contact a salvage yard or junk dealer, get a pre or after UFI armature plate and coils, you are ready to go!
( They did not revert to the 'old' system without reason!)
