That is what is called the super 6 by SUZUKI. The 150 dual plug was a choked down 225 basically and was frownedd upon by many of the BASS fishing organizations that had a 150HP rule. That thing was nowhere near a 150 at the prop, but much closer to 200. Not to mention the torque it had for a 150. I would think it would be capable of tearing your 18 footer up if your transom isn't as good or better than new. it is a heavy 150, but makes up for it in torque and the ability to turn a big prop.

As for the price of the OP's, I would say $3500 is more than fair if it checks out. You need to have him at least open up the crate and let you inspect it for any signs of corrosion.

Things I usually do when I check out a motor of any kind are:

1. Check compression. What type of compression should this motor have?
2. Corrosion as you mentioned
3. Signs of leaks and wear/tear

Do you recommend just filling up the fluids and starting it right up? If an injector is clogged what signs would there be? Also, if clogged would you remove all the injectors and have them cleaned?

Thanks,

For an engine that's been in storage that long, I would fill it with any oil it needs. For a 2 stroke like the 150, I would run it on 50:1 for at least an hour until you get the oil injection purged completely and verify it is working. Also before you start it or turn it over, i would put a tablespoon of MARVEL mystery oil in each cylinder and rotate it around by hand a few turns and let it sit for a few hours before you hook power up to it and turn it over with the starter. This will lubricate the cylinders and make sure teh rings aren't dry when you spin it around. Also it wouldn't hurt to spray it with WD-40 into the intake when you turn it over to put some lube down in teh rod and main bearings. I'm not sure what teh compression should be on that engine, but I would guess it should be around 100-125 if I had to guess. Just make sure they are all even with each other. And as far as the injectors go, I personally would have them ultrasonic cleaned before running it under load. I would do this for insurance more than anything as plugged injectors have taken alot of 2 stroke outboards to an early death.
