1995 Force Flooding issues?

I was gifted a 1995 Starcraft aluminum boat with a 1995 40 hp Force last summer from my dad. He purchased the boat brand new in 1995. I was used maybe a couple dozens times and was stored in the garage for a few years. No issues at the time, he just lost interest in fishing. A few years later he tried get it up and running again and ended up putting it in the shop and had the power pac replaced and the water pump also I believe. He took it out a few mores times and it ran fine but ended up sitting up in the garage a few more years until I received it last year.

I had it running last fall but had issues with it flooding after stopping and fishing for a few hours. I would have to pull the plugs and crank to clear the chambers of gas. After a few minutes I could get it running again. The motor ran great when it ran. During winter I replaced the fuel needle after doing some reading on the internet. I couldn't get it running after that so I took it to the shop my father used to use. I was told when I put it all back together that I had installed the float upside down. I felt pretty dumb after. I'm pretty new to all this. Everything checked out good and the motor ran great all summer, maybe over a dozen fishing trips. It was about as reliable as you could expect from a motor that old.

so about a month ago I took my stepson out fishing. I stopped and started the motor about 3 times with no issues until when headed in it failed to start. I assumed flooding so plugged the plugs as I had to do in the past. Nothing. Every 30 minutes I would try to start it up until eventually after an hour and a half I had it running. Ran for about 10 minutes wide open and then it sputtered a bit and ran wide open 10 more seconds and then cut out completely. Had to be towed in and havent been able to start it since.

I've been trying to start it the last two days and haven't had any success using the same old techniques. I installed new plugs to see if possibly the plugs were bad, they're easily 6 or 7 years old but were hardly used. I ordered a fuel pump diaphragm kit this morning so I'll give that a shot when it arrives. I was gonna get a spark checker to make sure I'm getting a spark but it's been raining all day so I'll have to wait till tomorrow.

I know it's a long story but I'm running out of ideas at the moment and just looking to see if anyone can relate. if all else fails I can put it back in the shop but I feel like it's gotta be something little that I'm missing.

Also, I'm looking at repair manuals on Amazon and was wondering which one was better. The Seloc one or the Clymer? Based on the reviews I've read I'm leaning towards the Clymer.

Re: 1995 Force Flooding issues?

Check on Ebay and see if you can find the Factory Service Manual for your motor. They are 100% better than the aftermarkets. You should definitely get the spark tester and test for spark. You can also pick up an inexpensive compression tester for about $10 at most big box stores. You only need "compression, spark & fuel" for it to run so you might as well inspect each system. Sometimes, sitting can be worse that something that's over-used. Outboards don't like to be ignored.

When was the last time the carbs were cleaned or rebuilt? With the service manual, you'll find that these thngs are pretty simple to do, just takes a little time. If it were mine, I'd do the compression test, spark test, clean the carbs, and then check the entire fuel system, replacing the fuel hoses that are cracked or worn. Most older boats/motors were not built with Ethanol in mind and those fuel lines can get flaky on the inside, causing that gunk to get into your carb. Post up your results after you do these tests if you're still having issues and one of these guys will walk you through fixing it.

Re: 1995 Force Flooding issues?

Thanks guys, I just purchased the service manual off amazon. I'll be headed to town later and pickup a spark checker and compression tester and go from there.

The only work the carb has done to it was me replacing the needle and the gaskets that that required. I cleaned everything with carb cleaner before i put it all back together. When I took it to the mechanic he said all of that looked really good and clean. He said he also adjusted the idle. The motor ran great all summer after getting it back from the shop until the last trip.

Thanks again and I'll keep posting here with my results.

Well I got my spark checker today and I'm not getting any spark so I guess I'll start looking at the ignition components. Got my service manual in the mail today so I'll start working on it this weekend. I remember my dad telling me he had the coils replaced years ago.

Re: 1995 Force Flooding issues?

did you check for the kill switch being loose ? If that is good try looking at the stator resistance on yellow and blue wires

Confirm that it's in neutral while you're at it, just to be on the safe side. Also, check your main cables as they can corrode and even "look" fine, but have issues.

Re: 1995 Force Flooding issues?

I've learned my lesson on making sure it's in neutral the embarrassing/expensive way lol so we're good there. Also checked and double checked the kill switch but I just got my manual today so I'll check to see if something is loose.. I took a wire brush to the cables going to the coils last weekend. this weekend I plan on cleaning or making sure all connections are good. After doing some reading I'm kinda wondering if it may be the stator. Is the stator something that can normally be serviced or does the whole thing need to be replaced? I ask because I was checking on the availability of one online where I normally order my parts and the stator as a whole is listed as obsolete.

Thanks for the replies.

Re: 1995 Force Flooding issues?

Quick question, is the kill switch connected to the motor in any way or is it just connected to the throttle control box?

Re: 1995 Force Flooding issues?

Not a "normal" part to go bad, but I guess anything is possible. There are magnets under the flywheel that there have been a few recent posts about one or two being out of place. That would cause a no-spark issue I think.

There's several threads on test ohms on the stater if you do in fact think that's the source.

Kill switch should be wired into your ignition.

Re: 1995 Force Flooding issues?

It sounds like you need to find out if you have spark in all of your plugs. If you don't then it could either be the coils(unlikely) or the cd modules ( @$450/ea). the best way to check without spending the money for a spark checker is to have someone turn the motor over while you hold each individual plug ( after having donned electric proof rubber gloves) and the coil wire to a ground and have your assistant turn over the engine. If the spark is intermittent or absent check the next one. If the spark is absent in both, it is likely the CD module. if it is only intermittent or none existent in one, which is unlikely, since it didn't start at all, it could be the coil,(less expensive) otherwise the cd module is suspect. The CD module is the box that is bigger than the coils but is mounted on the same ignition plate. Without a digital multimeter, you cannot be for certain that either is inoperative. However, this method is a physical way to determine whether or not the logical sequence is occurring as designed. From your description, you either ran out of gas or the CD module went out. (don't attempt if you have a pace maker. I am not a heart expert and don't imply your safety in this matter, only what I have attempted with no personal harm.)

Re: 1995 Force Flooding issues?

Well my wife's ex husband came over to pick up the step daughter while I was taking a look at the motor last night. He had just bought a running 40hp Force for the lower unit. Said I could come over and pick up the motor and take it for free. Went to go pick it up this morning and it's a 99' and has a different ignition system than mine. But I took it home anyways for a case of beer. I don't think I'm up to the task but he seemed to this I could maybe retrofit my motor with his motor's electrical/ignition components. I'm leaning toward not going that route and just go ahead and buy the correct power pack for my motor and part this other one out to cover the cost of the new power pack.

Just wondering if has anyone undertaken a project like this before and if it is even possible?
