1967 Chrysler 9.2 questions before spending $$$

[HDPipes05]

No manual yet as I don't want to spend money on it if its junk. Brief history, got it used for $30 from a friend who was gonna scrap it. Appears to be in real good shape, said to run and has been used in the last year but has a cracked transom mount bracket. I can acquire one for $55 including shipping. P/O didn't want to tinker, just wanted it out of his garage.

Compression in both cylinders is about 85. Seems low to me, any one know what it should be roughly??

Also, I pulled the oil drain and got about 3-4 ounces of water and only 1 ounce of sludge. APPEARS to go in and out of gear ok.

I'd really like to give it a good paint job and use as a emergency kicker motor for my cruiser. before I go spend good money on a manual, paint, impeller and bracket for a limited production motor I just want some info.

Thanks all!!!

Sounds like mine with the water in the gear oil. I was winterizing mine last month and drained the gear oil, only to have a flood of water pour out. My buddy said the prop seal can go bad and I'm sure for a 36 year old motor that seal is done. So I put new oil in, but come spring, I'll tear it apart and put all new seals in. I can inspect the water pump while I'm at it and get it in top form.

The compression should be higher. My compression (I was told by PO) was 130 in each cylinder. Sounds like 85 is ready for a rebuild. If it runs, you could get some use out of it. Don't know what an overhaul costs for an outboard, so I won't guess.

Are seals and rings even available for these motors anymore???? They were only made from 66-67 I believe. Can't imagine finding parts is gonna be easy, especially the rings and/or pistons.

Re: 1967 Chrysler 9.2 questions before spending $$$

Don't panic on the compression.100 psi is considered ideal minimum.It will run on 85 no problem.Sometimes a de carb treatment using something like Sea Foam will help compression.On the gearcase there is a prop shaft,drive shaft,
and shift rod seal.I think I would leave the seals till you are sure it will run.
Put the lube in and try her out and make a decision on the seals.

Re: 1967 Chrysler 9.2 questions before spending $$$

factory specs acording to Clymers is 105-115 PSI. Like Steelspike said: It will run fine at 85.

Anyway, low compression could be due to the gauge itself or the person taking it. It could also be due to the engine not having been run in a while. Start it in a barrel and run about a half gallon of 25 to 1 oil mix through it then check the compression.

Normal fuel mix is 50 to 1.

And don't spend 55 bucks for a transom clamp. Go over to The Chrysler Crew and see if anyone in the classifieds has one.

ALL Chrysler engines used standard seals. If you carefully remove them so as to not destroy the numbers, a bearing retailer will get them for you. These guys usually know their business and can often tell seals and bearings without numbers too. BUT specify stainless garter springs--twice the price but required for marine use.

As for other parts, contact franzmarine.com. He tends to be a bit expensive but was a Chrysler dealer for years and WILL have what you need.

Back to that clamp---If you absolutely can't find one then PM me. I have a couple of 9.9 and I suspect the clamps are the same---55 bucks, Hmmmmph!

Re: 1967 Chrysler 9.2 questions before spending $$$

Thanks for all the great info guys....

Here is the update: I put the motor on an actual engine stand. pulled the carb apart and gave all the passages a good blast with carb cleaner and soaked them for a while. Next, I put carb back on, re-adjusted the spring return for pull start, gave her a slight once over with a rag, greased all zirks etc. I then re-checked the compression. GOOD NEWS, got it up to 110ish on one cylinder and 120ish on the other. I was able to pull it over harder on the stand. About 6 times each to achieve the new numbers. I also replaced the plugs, and filled the lower unit. I don't have a vacuum pressure gauge so maybe being full of fluid Ill get a hint of where it's leaking from.

Tomorrow she gets the old bucket test. I couldn't tonight cause the little lady is getting irritated Ive been in the garage all afternoon.

I'll keep posting my results on the re freshening of this old Chrysler. Its actually older then I am!!!!!!

Thanks again all,

Normal fuel mix is 50 to 1.

I am new-ish here and don't mean to insult any one by questioning you, but are you sure about this 2 stroke mixture???? I read some place that it is actually a 24:1 mixture. Before I fire her up can your or some one confirm this for me??? Manual is getting ordered today so I won't have to bug you guys with this silly stuff.

Thanks as always.

Re: 1967 Chrysler 9.2 questions before spending $$$

Frank surely knows what he is talking about.
Heres what I found my aftermarket 72 service manual indicates the center and lower mains are friction bearings.To me that means 24:1 as indicated by my manual.I would suggest you use 24:1 until we here from Frank.

 

[HDPipes05]

Re: 1967 Chrysler 9.2 questions before spending $$$

Yeah I need to confirm before I run it off the stand. I have a half gallon of 24:1 mixed up now to test her out.

Thanks!!!

Re: 1967 Chrysler 9.2 questions before spending $$$

NEVER feel bad or think a question is insulting!

A lot of times I am on late and sometimes my brain is a bit addled.

BUT in this case I can't use that excuse: My Clymers only shows a 9.6 in the illustrations while it lists the 9.2 in specification tables, and the 9.6 has roller bearings. So: I assumed (*** U me) that the 9.2 would be the same. My fault. BUT if the 9.2 has plain center and lower bearings, that would indicate 24 to 1 mix. Seems odd that an engine as late as 1967 would still use 24 to 1 but the 3.6 was a plain bearing engine and used that ratio.

The critical bearing is the rod big end. That takes a hell of a lot of abuse. If it is plain, 24-1 is required since 50-1 will not physically have enough oil to work into the bearing space. Since the oil will tend to settle out of the air/fuel mix, it will gather around the crankshaft main bearings and lubricate them no matter what they are.

So, could not hurt to run on the safe side at 24 to 1. Worst that happen could happen is you need to clean plugs more often.

For a definite answer, come to the chat room at The Chrysler Crew tonight at 9 PM eastern time. Franz will know for sure. There's a guy who has forgotten more than I'll ever know.

Frank, thanks for the insight. Ill just go with 24:1 as you said until proven other wise. I have been wanting to get on the Chrysler forum for a couple of weeks now but unfortunately I have to get up at 3am so I am usually sawing logs by that time. In fact I'll be retiring here soon. Thanks again guys!!!!!

Not bad for $30 now that I know internally she is OK

Re: 1967 Chrysler 9.2 questions before spending $$$

those are good motors. I have the sister 6 hp of that year and the sister 20 hp of that year also.

 

[steelespike]

Re: 1967 Chrysler 9.2 questions before spending $$$

My 72 manual does say the crank pin is a roller bearing.Also piston end of rod is roller bearing.As Frank says these are critical.

Re: 1967 Chrysler 9.2 questions before spending $$$

Franz said that ALL WATER COOLED Chrysler engines are 50 to 1 ratio. Only air cooled models are 24-1 ratio.

Re: 1967 Chrysler 9.2 questions before spending $$$

what wt grease or oil do you use for the gearcase ???

I dont know how to look that type of thing up
