Default Outboard gurus

I dont really know chit about them other than theyre too quiet.

Im looking for a used/ fairly fresh rebuilt 2.4 Merc or similar.

What do I need to look for when buying used, ive noticed a lot of guys seem to post induvidual cylinder compression in their classified ads......what is good compression for theese motors? Can I use a gaffrig style throttle / shifter setup or does it have to be one of those goofy huge control boxes like you find with most outboards? Anything to worry about in the lowers, or are they considered "not a weak link"??? whats the typical lifespan of a powerhead? Anything else I should look for or ask about?

They have not made 2.4's for at least 10 years. The compression will depend on the powerhead. Go to www.Screamandfly.com and ask this same question.

If you are repowering, you may want to look into 2.5's. The 2.4's were basically grenades.

Are you looking for 2.4 BPs. If so they are good engines. If possible try to stick with 2.5 260 or 280's. BTW what kind of boat is it going on?

go 2.5, the 2.4 are too old and the parts are probably getting hard to find try jaco marine .

Question Re: Outboard gurus

What kind of boat are you planning on putting it on, the 2.4's + 2.5's are better for a lighter boat and the 3.0's are better for a heavier boat. Scream&Fly is the outboard resource but there are some of us with mixmasters here also.

The compression will vary depending on the type of motor you are looking at, the higher the compression the better your fuel needs to be. The important thing is that there is minimum differences between cylinders

Can I use a gaffrig style throttle / shifter setup or does it have to be one of those goofy huge control boxes like you find with most outboards?
Yes you can use Gaffrig style throttles and shifters.

Anything to worry about in the lowers, or are they considered "not a weak link"???
This depends on what you are using the motor for and what gearcase it has, if you are looking for a high performance motor you would want a sportmaster or torquemaster gearcase depending on how fast the boat you are installing the motor on will go.
whats the typical lifespan of a powerhead?
I think that a powerhead that is well maintained and run with clean oil and fuel should get 1200 hours unless run at very high RPM's all the time.
Anything else I should look for or ask about?
If you can tell us what kind of boat it's going on and what you plan on doing with it we could probably make better suggestions.
