Advise please!!!!!!!!!!

Problem: When driving the boat at above idle speeds the entire motor or drive system "kicks" almost as if hitting a log under the water. It will do it probably 3 times a minute. It is progressively getting worse.

Took it to a local guy who told me that he hasn't check into it yet but it has the original shift cable and the original dogs. States that there was a recall in 86 that was never done and that its probably the issue. He stated that the cable was 200 and the dogs were 450 and the cost to put it in would be upwards of 1200.

I dont know what DOGS are im assuming they are some type of gears. I asked if i could just do the shift cable he said yes but he isnt sure if that would fix the problem or not.

The boat: 1986 sport craft 4cylinder 140hp chevy motor Cobra OMC drive. boat is in good shape other than that.

My question: is this something i can fix myself or are there special tools/knowledge involved in replacing these gears/dogs if i decide to.
Is there a location where i can purchase replacement gears/dogs at a lower cost.
If i just run it what will eventually happen
Could just replacing the shift cable fix my issues
is there a way i can tell if the dogs/gears are bad without getting into a major project?
THanks

Re: Advise please!!!!!!!!!!

You can't replace gears and shift dogs without the special tools. Just no way to set gear heights and patterns without them.

It's possible, but highly unlikely if this problem has been going on for a while. Give it a try

is there a way i can tell if the dogs/gears are bad without getting into a major project?

Nope, only by looking at the gears and seeing how rounded over the dogs are can you tell the amount of damage.

Howdy,


Welcome aboard!

You have a fairly common problem with your Cobra.

First of all, you need to do a little reading to educate yourself on the Cobra and it's history. It will help you understand what your mechanic is saying and why he thinks you need the service he's talking about.

Read the following info. http://www.hastings.org/~stuart/cobra/

If i just run it what will eventually happen

You WILL destroy the drive. (and it may be damaged enough already to require a rebuild)

Could just replacing the shift cable fix my issues

That MAY fix it (but only if there's no damage to the "dogs")

is there a way i can tell if the dogs/gears are bad without getting into a major project?

You cannot see them from the outside......


Everybody else here types MUCH faster than me!!! (Especially Don! )


Cheers,


Rick

I replaced my shift cable this spring after experiencing the same symptoms as yours, & I haven't had a problem since. So u may luck out & cure it with just the cable replacement. It depends on how long u ran it with the bad cable.
