89 Force 125 problems after running and trying to recrank

[JT3]

OK so I have a 89 outboard force 125

it runs fine at first, takes a little while to warm up as normal...but after i've been going for awhile and I decide to cut it to fish (fish and ski) well after I cut off the keys for awhile and use the trolling motor say maybe 30 min. I try and crank the boat and it just turns over with no spark or hint of starting to the point that one time I actually ran the battery down

so it runs fine for awhile and then it just wont start back after a bit of inactivity


any ideas?


and where or how can i go about getting ears for the engine, will a hose hooked up to it reallllly close to the vents work fine?

Re: 89 Force 125 problems after running and trying to recrank

An engine only needs a couple of things to run

Fuel, spark, compression

The fact that it runs at all means that you have all the above so the problem is determining which one is so weak that it fails to start once warmed.

The very first place to start is to remove the spark plugs and take a hard look at them, what do they look like, black sooted, crusty with a gap worn out to about 3/16 inch? It could be that it is simply time to screw in a new set of plugs.

Search this site for a homemade spark tester, make one and test the spark to rule out any ignition problems.

Next, move on to testing compression, once you've then proved the engine mechanically sound it is time to move onto the fuel system and clean your carbs.

Do these things in order, it will save you a LOT of money and frustration from buying expensive parts that you may not need.

You said "it just turns over with no spark ".

Did you actually check for spark?

I would be the engine is flooding while you are fishing.

so whats a way to keep it from flooding

I cleaned the spotless Carbs, they get cleaned every few months, just changed plugs and keep the thing pretty clean in general

just wondering what would cause it to flood and if there was any way to stop it? sounds like that may be what the problem is, makes sense because a few hours after its been acting up it will crank back fine.

but ideas of how to stop it?

When was the last time the carbs were rebuilt?

I purchased it about a year ago and according to the seller they had been rebuilt not long before the sell, I took a look at them and they were really clean, seemed to be in great condition.


link me to a place or words about how to check and see and rebuild them if you can

When you say it takes a while to warm up, do you mean to say that it takes a couple of minutes before it will run without stalling when you put it into gear? You could take the air horn off while you are out on the lake and use a spray bottle with some 2 cycle gas ( never starting fluid ) and spray it into the carbs to see if you are not just having a fuel delivery problem ( running lean ).

no, it runs fine off the trailer...thats not the problem...it runs great and has great pick up from the get go, i dont think you understand the problem^


its when it SITS in the water after its been running for awhile that it tends to not want to restart

it gets gas to the engine i can see that in the line no problem...and the starter wants to turn it, but it seems like its just not going too

the flooding problem seems right

WHAT would cause it to flood tho?

Check your coils, Many times they work fine until they heat up , most times its a very small crack in them thats very hard to see.

You mentioned that you was wanting to know where to buy ears for the engine. I have an 87' 125 and I found mine at the walmart. Made by seasense, they're only about 5 bucks (if i remember correctly). So as far running the water hose really close to the water intake. Chances are, you will just be blowing the water out the other side and it wont make it up to the water pump impeller. which is very very bad. Your next post may be about changing the water pump or worse. Spend the money, it will save your engine.

The #1 cause of flooding like you described, is the fuel pump.

It leaks from the inside, into the block, where the fuel usually settles and floods out the bottom, or bottom 2 cylinders.

You can get a fuel pump rebuild kit for under $20, and it will take about 30 minutes to put it in.

sorry it took so long to get back to you, I've been sick.
