Chrysler 90 HP Choking Problem\Pictures

[kohath]

Hello;<br /><br />I have a 1983 Chrysler 90 HP Outboard motor. I was having trouble getting it started, and did post a message yesterday about the problem. I went out a few minutes ago to work on the motor, and, lo and behold, I noticed the choke was not engaging when trying to start the engine. You would think I would have noticed that before, especially since the carb throughts are pointing straight at me when I turn the key to start the motor, but since I know very little about outboard motors.....Duh, I think the choke works the same on just about any engine, so that is not an excuse!!!<br /><br />

<br /><br />Anyway, I put a bungee on the choke lever for the two carbs to hold the choke butterflys closed, turned the key, and boom, immediatly the motor fired up. So, I assume there is something amiss with the choking module. The owner's guide states that when the key is in the "on" position or the "start" position, the choke should be "on". But, when I turn the key to the on position, the choke module, and therefore the choke butterflys in the carburator throughts, do absolutly nothing.<br /><br />

<br /><br />The choke module is the brass colored module mounted on the engine between the two carburators. When the Choke module engages, it pulls on a lever that closes the choke butterflys. I assume that is what is supposed to happen. And then, when the engine warms up, the choke module should open those two choking butterflys. This is what I assume is supposed to happen. If I am incorrect, please someone inform me in this post. <br /><br />

<br /><br />Anyway, I am thinking the problem is either in the module, or in the key switch, or the wire that goes from the key switch to the module. Could I test that module by directly touching the hot side of the battery to where the green wire going to the module hooks up on the module. I don't want to damage the motor if at all possible. I would disconnect that green wire first. <br /><br />Any help on this from the Boat Motor experts on this board would be appreciated. <br /><br />Matt<br /><br />

When you go to start , do you push in on the key at the same time. I know that's how my Chrysler is choked.

Re: Chrysler 90 HP Choking Problem\Pictures

Thanks scotiany;<br /><br />That did the trick. Next Question, why is it that so much bad talk is made about the Chrysler Engines. I've only owned two boats, so I am far from an expert at boat engines, but the only qualm I have about this motor is it drinks tons of gas. It's like, I could pour the gas overboard and get about the same gas mileage! Is that normal for all outboards, or what. No leaks, etc, the motor just drinks it like there was a direct line from the gas tank to the exaust of the engine.<br /><br />Matt

Re: Chrysler 90 HP Choking Problem\Pictures

Matt...congrats...the bad talk about Chrysler outboards comes from folks that don't know much about outboard motors mostly. Most of these motors are 20-30 years old and have similar problems to other brand motors, actually less problems. They were state of the art when they were manufactured...Chrysler motors got bailed out of financial trouble in 83-84 and they had to sell off all their subsidiaries...byby Chrysler. They are old motors and some parts are tough to aquire.<br />Personally, I don't normally say anything when someone calls them junk, usually means I can spend less money next time I go looking for one...just my humble opinion

Re: Chrysler 90 HP Choking Problem\Pictures

I agree Thought101. Since it's been 4+ years since I had the boat out, I probably forgot about the choke\Key switch routine. If these motors are so bad, why, (after the operator finally understood how to start the motor), did the motor fire up, immediatly. I have tried starting the motor a couple times now and it fires up immediatly, when I have the choke engaged. This boat and motor sat underneath the back porch of our house for the last 4+ years. I did not do anything to the motor for before "storing it", etc, and you should have seen the boat. Filthy dirty. Spent 10 hours cleaning it, the skies, etc, etc. No joke, either. Along with the cat hair in the boat. As bad as cat hair is, it sure beats having mice in the boat. So, I let the cat use the boat as her own personal "cat house" whenever she wants. She keeps those pesky mice out of the boat, and anyone who has had mice in the boat knows they can sure stink it up, literally. So, I would not put down the Chrysler engines, unless, of course like I said, I can find other engines that don't drink as much gas.<br /><br />(I did put plastic bags in the engine ports. If I don't, the Mud Dobbers, notorious here in Missoury, will use the boat cover as their own personal breeding house. I learned that lesson years ago!)<br /><br />Matt

I don't know where you are in Missouri but, they're having the Chrysler Nationals at a place called Stockton Lake. Those guys are true Chrysler OB fanatics and experts. Check out their Thursday nite chat 9-11. It's called the Chrysler Crew.

Re: Chrysler 90 HP Choking Problem\Pictures

Thanks for letting me know that, scotiany. I am about 20 miles from Stockton Lake, and that is where we go boating. They had quite a tornado there a couple months ago, missed us by about 10 miles. I am going to take my wife and 3 little girls, 2, 4, 6, and take the boat out there for the first time in 4+ years. If I can just remember the drain plug. I left it out one time many years ago!<br /><br />Matt

Re: Chrysler 90 HP Choking Problem\Pictures

Just adding my 3 cents worth on chrysler. I purchased a 120 Hp Chryler from a guy who told me it had sat for many years unused. Just last saturday i finished my 9 month long project boat and took it out to the lake for the maiden voyage. Dropped the boat in the water, primed the fuel bulb, choked it up, and let her go. Fired right up. Needless to say,,,, I am completely pleased with my $150.00 investment.

Re: Chrysler 90 HP Choking Problem\Pictures

I also forgot to mention,,,, that is the cleanest motor i have seen in a long time.

Re: Chrysler 90 HP Choking Problem\Pictures

If you are talking about the motor in the pictures, you are right, it almost looks brand new. It only has around 80 hours on it. Kinda amazing for a motor that is 20 years old, 1983 model. I suppose there are other motors out there with few hours on them like this one. Someone buys the boat, uses it a few times, then it sits in the barn or somewhere for years, etc. I did not use it for the last four years because my wife kept having kids. It's all her fault. Anyway, I bought the boat from an older woman in 1990, her husband had passed away, and she wanted to get rid of it. Obviously they used it very little. And I have probably put around 40 hours on the engine, so that is why it is just about like new. I will find out how well it runs tommarow.

Nice '83

Re: Chrysler 90 HP Choking Problem\Pictures

I was wrong, it's the Chrysler Marine Home Page. BTW, Walmart has drain plugs for about $3.

Re: Chrysler 90 HP Choking Problem\Pictures

Yep, that motor is a beauty! If you keep it in good tune, decarb occasionally, and 'winterize' it when stored it should last for many more years.

Re: Chrysler 90 HP Choking Problem\Pictures

BTW, Kohath....you did replace the impeller, didn't you?

 

[kohath]

Re: Chrysler 90 HP Choking Problem\Pictures

Fouled Plug, Where can I find an impeller for this motor. I checked with iboats and Sierra with no luck. Any suggestions?

Re: Chrysler 90 HP Choking Problem\Pictures

Kohath:<br /><br />What a clean motor you have! Can you provide with further pictures as the cowl and lower unit? Can you provide pictures of your boat? What HP rating do you have? Perhaps your boat is boat of the month at the ChryslerMarine website!<br /><br />Have you dealt with the gasoline consumption of the motor...is the propeller correctly pitched for your boat weight?<br /><br />Look forward for wour pictures!<br /><br />rbruce63

They are pretty crummy motors. I have a Yamaha kicker which is much older and beat to crap, and it runs much better than my force. I would never consider buying another one. It starts up right away, but it's poorly made from cheap parts. Leaking lower unit, replacing parts constantly, no tell tale, poor availablility of parts, built to be the cheapest possible motor to manufacture for the equally crummy bayliner boats, to get something on the water for the least dollars possible in design, manufacturing, etc. They were cobbled together from a bunch of leftover and obsolete parts, 20+ old tillotson carbs, whatever was cheap and available.
