Need motor Help

well thought i had my motor fixed but no good still .it runs all day but runs rough and kinda missing
ive changed all the fuel lines they were bad i didnt change the ball yet and it dont pump up hard
iam lost i called a marine guy and he wanted 150 just to come to my house dont have a lot of money but if i have to i guess i will save up to get it fixed ..
i thought having a boat was gonna be fun lol ive been stressed about it for a month now ..
any ideas ?
or anyone near Titusville that knows how to work on these things ?

All I can suggest is run some seafoam thru it and maybe that will help some. Hope you get it right!

First replace your bulb. Then find someone with a portable gas can and put 2 gallons gas, correct amount of oil and 2 cans of sea foam. Start your motor and run for 15 -20 minutes and shut off and let sit overnight. Next day repeat but let set about 3 hours and repeat until your can is empty. Then repeat with same fuel mix with seafoam and take to river or lake and run full throttle for 15 minutes and half throttle 15 minutes and let sit overnight again. Then run again until fuel is gone. Add 1 can of seafoam in 6-10 gallons of fuel from that point on and should be good unless you have grit in jets. then time for a carb rebuild. I would suggest investing in a fuel/ water seperator/ filter for future. And dont worry about mix ratio on seafoam can, you can not over concentrate it just treat it like fuel and add oil mix appropriately. Hope this helps ya. Fixed my old motor right up and starts on first pull and never misses a lick.

X2 what Huntinslabs said!!

Just be prepared for A LOT of smoke if it's an older engine and hasn't be de-carbed before. I wouldn't run a boat without a water separator with the ethenol fuel we have now either. Good Luck, and hang in there. These fuel issues can drive ya crazy, but work through the steps and you'll get it sorted out.

1 more question for guys thats had boats a long time ,Have you ever had the primer ball make your boat miss and just not run right ?
i mean it runs even WOT it dont bogg down like its out of gas is why i am so puzzled lol ..

Sounds like crud in carb. Try the seafoam.

Yeah, ya got to have a "breather hole", generally in the cap of the gas tank (portable) so, as the gas is sucked out it doesn't creat a vacume in the tank and
stop free flowing out, etc, etc ...
Most built-in tanks have a seperate breather tube somewhere in the top of the tank ..............
(I used to fabricate gas tanks for pleasure boats (hidden tank), etc, etc .......

Hey Sim,
Discount Auto has Seafoam for $3.00 off right now which is a pretty good price, buy a new primer bulb as they are cheap and try to find a small external gas tank and run your boat with this setup. This will help to start eliminating certain issues in your fuel system. Also try listing what motor you have and maybe someone might have a factory manual that could give you the resistance specs one some of your electrical components. Hopefully you can get lucky and find the problem. Good luck!

I am gonna get some Seafoam tomorrow and a tank and bulb with line ..
Motor is a 85 evinrude 235 hP ...i do need to buy a book if anyone has 1 they no longer need ..
phantom you didn't work for Searay did you ?

1 guy in another section told me to pump the ball up with it pointing up right and i did it worked that way so i was just wondering if the check valve was bad would it do what mine is doing ..
i have had carbs off and looked in them clean but i didnt take the jets out ..

Had a speck of something in bottom of carb awhile ago. Did not missfire but would only idle. Seafoam is good stuff for desolving deposits but does not remove trash. Dissasemble carbs and blow out holes and ports.

Nope, never worked for Sea Ray .......
No sense taking carbs off without cleaning jets ..........

You might want to check this site out. It only cost $7.95 to download the manual you will need.

I don't know if this applies or not but I had a problem with my 1985 70HP Johnson. I changed all the main fuel lines with ethanol resistant lines and still had a problem. It turned out the small hoses at the fuel pump had come apart internally as a result of the ethanol fuel. I replaced them and rebuilt the carbs and haven't had a problem since. Like Phantom says find some non ethanol fuel to use!

Had a problem with small hoses inside motor crumbling etc. Was told to replace with same size from motorcycle
repair shop and they would not break down as soon. No problem since.

Update i replaced the Primer bulb and tightened all clamps on the main line took it to the lake and it ran really good but still has the same problem but not all the time as it did .
i thought i heard air when i squeezed the primer so i wonder if i got a bad 1 .. also boat never idled this good so i guess i am headed in the right direction ..
going to run Seaform threw it and see if that fixes the rest of the problem ..

That's good to hear, sounds like you may be on the right track. I still think it would be good to try to run off an external tank to eliminate anything that might be causing an issue from your boats system, plus it would be a good way to put some Seafoam thru it. I'll check at work to see if anyone has a tank you could use, I'll let you know.

Ace Hardware has a 6 gallon tank on sale for so I will prolly get that because I need to run my tank out of gas anyway to remove it to fix some live well hose.

Well gonna put the Running problem on hold found water in the foot oil So ...Hope i get it fixed soon those fish are waitin on me lol ...

UpDate .. Got the water in foot fixed and replaced the water pump bad gasket also the housing didnt look to well lol .. Found a new problem my Regulator /rectifier is bad charges the battery to 16 volts at idle.
1 thing i dunno is if to high of volts could make it run bad . and the trigger base is sticking a bit so after i get the money to buy a reg well see how she runs ..
Thanks for all the help ...

If your trigger shoe is sticking TADA thats more than likely the culprit. Might as well change the stator while your under the flywheel.

My Mariner has 2 power packs(switchboxes) and had set for several years before I got it. When displayed on a spark card there was spark on all 6, but it was white, not blue. Long story short; trigger was faulty, Carbs had to be redone from residue the first thief left behind(disassembled and blew out with carb cleaner and charged $60 per carb)and one power pack was too weak to keep up with the other, and they need to be replaced in pairs. Fuel line broke down and fuel pump and filters had to be replaced.(and the line did it again a year later). It starts quickly now when cold and like an old chevy when warm. Sometime in the future, sooner better than later, have a GOOD tech run an electronics diagnostic on all your parts cuz it will never perform right til they are up to par. All the fuel system advice so far is spot on. My fuel lines let chunks of rubber into the system that blocked the JETS with no evidence in the bowls.
