88' 4 Winn's engine troubles

This is a 4 Winn's 160 4 cylinder OMC inboard that was stumbling under load last year. Lower speeds it ran fine,but at higher speeds it stumbled. Boating mechanic said it needed a new carb. I started to remove the carb, and when i got to the fuel filter i noticed it was gunked up. My question is,could that have been the problem?

Second question:
Tried to start the engine and all i got was a click,click.
I have a fully charged battery that reads well with a load.
I cleaned all the terminals and such,and am getting juice to the starter solenoid. I tried the old trick of rapping on the starter,but no luck. Am i needing to replace this two year old starter?

Thanks for any help.

For your first question, yes the dirty filter would cause a restriction and be noticable at high speed more than low. I would replace the filter and retest if the carb is still on the motor. If you have removed the carb I would buy a rebuild kit and make sure all the passages are clean. I would also look aty the cap and rotor, this would also cause a high speed miss.

As for the starter it sounds like it should be replaced. Check connections to make sure they are clean and tight.

I would say 90% of marine starters go bad due to water weather it be a drain plug left in the boat and it fills with water where the starteris actually under water. Also with covered boats there can be some water in the hull and the heat under the cover causing very high humidity. The best thing for a starter and other electric components is to pull the drain plug and leave it out. If possible open engine compartment as well as ski lockers and other compartments to let them completly dry.

Before you replace the starter ...

Does it look something like this with the solenoid on top of the motor?

You shouldn't have to remove the starter assembly. Pull the nuts that hold the wires to the solenoid, then pull the second set of nuts. Pull the bolt that connects to the rod that disappears into the top of the motor through the rubber grommet. Pull the cap that holds the electrical connections off the solenoid. You'll be able to move the cap enough to get at a large washer inside the cap.

The washer makes contact with the high-current battery wire. The washer may have a buildup of carbon from the constant electrical arc that happens every time you turn the key. You can clean it with sandpaper, or turn it around so the clean side will make contact.

It's worth a shot -- and a whole lot cheaper than spending the big bux for a new starter. I did this several times over fifteen years on the '86 Four Winns I used to own.

Thanks samuari and Rick,

I replaced the gas filter,and working on the starter issue.
I guess i'm not surprised now that starters only last a couple years.
The transom plug is always pulled at the end of the day after trailering.
Great help guys and thanks.

Follow up:

I have got to the point of removing the starter either to replace,rebuild.

Rick,the starter looks similar to the one you posted.
A marine supply has two starters that may fit,BUT i don't know which one it is as the bolt holes are different. However, if i could find a source that had a picture i might be able to say that is the one.

All the info i could get off the starter is as follows
Wright electric motors with these following #'s
sae 1711 j 10266c

Any suggestions?

I tried to look it up but i'm not sure if it is a 3.0 liter or a 2.3.
The 2.3 is a ford and the 3.0 is a gm they were both used that year. If I can I'll post pictures of each.[IMG]<a href="http://s400.photobucket.com/albums/pp89/chetolson/?action=view&current=ACF26521.gif" target="_blank"><img src="http://i400.photobucket.com/albums/pp89/chetolson/ACF26521.gif" border="0" alt="Photobucket"></a>[/IMG]This is a 2.3 ford starter.

samuari,

The engine is a 4 cylinder 3.0 liter G.M.

Boy!! Is this becoming a "bear". I checked with a marine dealer and there is 2 types of starters for this engine.
So i proceeded to try and remove the starter and can't get to one(?) bolt.

You wouldn't happen to have a picture of how the starter is R/R ?

many thanks

I can't find any pictures of the starter removal but I can tell you how I do it.
First disconect the ground from the batt.
Remove the 2 starter retaining bolts usually 9/16 head The one away from the motor is sometimes visible the inboard one is a little bit forward "twords the bow.
Then I move the starter and remove the wires from the back.
I know the four winns are tight so I look and try to remove the board on that side of the engine compartment.

When you put the new one in, do not overtighten the bolts! They look beefy, but they snap easily. (That's experience talking!)

Well some progress today in getting one bolt out,however the 2nd bolt is tight to a shield,probably for flywheel,enough that i can"t get a wrench or socket on it.
The shield looks worse than the starter to remove.

I guess I'll pack it in and take the boat to a marine repair shop.

Thanks for all your help

Well it sounds like you gave it a good shot, Four winns is one of the hardest boat brands to work on that i've come across. They are great for the consumer with all the storage in the back but it makes it a pain to work on.

Will have it checked out,and buy another one if its bad.

Will keep posted.

Bought a re-built starter and installed it.

Now that problem is solved,i have another one ,but its easy for you guys.
I want to replace the fuel filter,but have forgotten which way the filter is installed... Its one of those
paper accordion ones that has a hole in one end ,and is about a inch long . Should the hole end be on the fuel side,or the carb side??
Thanks much

Sounds like your almost on the water!

I think the hole goes twords the fuel pump but I'm not positive.

Ya! I hope so.
The reason i asked was i forgot how the filter orientation was when i took it out.

Hopefully, i'll check it out this coming week end if the weather holds.

Follow up:

Hopefully the issues have been solved by new starter,and new fuel filter.

My son and i took the boat out this afternoon and put the boat through its paces. I'm happy to report that it started and ran like a top.

Many thanks to samuari and Rick for your help and support.

Glad you got it solved, but ... Two starters in two years? Take a close look at the one you just pulled out to see if there's a pattern of corrosion. Did you buy an automotive starter? Or a reconditioned marine starter instead of a new one?

I'm asking to satisfy my own curiosity. Why did the two-year-old starter fail?

I'm not sure why the first one failed,but i think it was because of moisture and corrosion. This second one is a rebuilt marine starter which had seams,electrical connectors,and anything else where water/moisture could get in sealed off with caulk..



The rebuild shop said they do a lot of these starters
