Hi Brandon! Welcome to iboats!

What do you know about the engine as far as an maint that has been done in the last year or so? Did the previous owner say any thing about how it ran or did you hear it run? Maybe might even do a compression test on the cylinders before trying to start it. The compression on each cylinder should be within 10 > 15% of each other.

I think I would at least start it up, or try to, and see what she sounds like. See what kind of temp the block runs at. You can do this in the drive way using flushing muffs. Remember, do not start it up unless you muffs or the engine is in the water, wether it be in a garbage can or in the water on the boat. Most times engines start very easy on muff cause there is no back pressure on the cylinders. If you have a large garbage can you put under it and fill it with water, that would be better. Remember to get the water well above the mating line of the lower unit and midsection so the pump is covered and will pump water.

If the temp seems ok, take it for a spin and see what it does through the throttle zone, from idle up to WOT. Should be a smooth transition from idle up to WOT.

Once you know what it does on the water or out, you can go from there to determine what needs done.

Re: New but used

Thanks for the welcome and advice... I say it was a 78 but thats the year of the boat I am going to have to find out about the motor... Its an electric start so should I just put the trash can with the motor down still attatched to the boat?/?? I am thinking about just pulling all the wiring out of the boat and starting from scratch... I dont know where anything goes its all jimmy rigged together... Anyone have a diagram for that... I ordered a manual online and am waiting for it to show... Any other tips would be great.. Thanks for the help

What is WOT? Like when you say it should be smooth from idle to WOT?

Re: New but used

WOT means Wide Open Throttle. Sorry Neal. Sometimes we take for granted everyone knows those little acronyms we use a lot.

Once in gear, you should be able to advance the throttle from idle to full speed and get a smooth acceleration to wide open throttle or full speed.
