Just bought a 78 Chrysler 105. What are the issues with these motors?

[my05hammer]

My brother has stated that the Chryslers are a dirty word in the boating world. How much truth is there to this, I mean really, I have not had much luck at all with the Johnson V4 I have and If the Johnson doesn't run this weekend I am pulling it and running this Chrysler I got.

The Chrysler looks like its only got a couple of seasons on it and the seller said it ran like a top and came from a wrecked boat. I have cables ordered and a control stand off ebay.

What are the biggest problems with these Chrysler motors. How come my brother is hating on them so much? One of his friends said that every time I take it on the water I'll need to be towed home. Really? It can't be that bad or any worse than any other outboard can it? The only thing I am finding to be scarey is the limited parts availability. But this motor was rebuilt and only has a few seasons on it and it is super clean, and 100% there with no rigged parts.

They're hard to find parts for! That's really it.

My '71 Runs like a dream

Take care of it and it will last you.

I have a buddy that SWEARS by Chrysler and has been running their engines since before I was born!

You know that's what I thought about it too. If its in good shape and runs well, it should last. But all the boaters that I have run into have no clue how to take care of their cars let alone a boat motor. I love working on engines and getting them tuned properly then caring for them afterward. I feel like I got a great deal for $350. It was rebuilt and has a couple seasons on it but looks like new. Either way I guess I will be on the water soon either with the Johnson or the Chrysler.

That's a 105 in the avatar. Sweet running engine with a marvelous exhaust note. HOWEVER: it is not really a 105. A couple of years later, Chrysler downrated it to a 90 at the prop. Original engine was rated at the powerhead.

Nonetheless, It was still the workhorse of the Chrysler fleet and as the lowest horsepower 4 cylinder Chrysler, probably one of the better running ones. Keep oil in the gas, do proper maintenance, and don't abuse it, and it will probably outlive you.

Thanks for all the help guys.

What ratio of fuel to gas? The Johnson calls for 50 to 1. Is 50 to 1 the standard for all boat motors?
