Anyone here familiar with marine outboard engines. I am getting ready to buy a boat, and I am one step away from doing so. It is used, and i compression tested it. 130 psi in all cylinders, +/- 1-2 psi. Being that it is a 2 stroke, I do not know if this is where it should be. anyone?

The compression it should have is dependent on the specs of the engine. If you can post up some more info on the engine we can get a better idea. Generally though, it's good when compression is even across the board and 130psi is a reasonable number for some 2-strokes.
Funny, I am getting a boat giving to me . I have no idea how it works was going to start researching it today .Guess I will wait and see

Wow that's an old model. At least from the 70s or early 80s. The compression sounds good because it is even. Make sure you check the gear lube oil on the lower unit. If its white or foamy than you have water leaking into the lower unit gear box. If the outboard has only been used in freshwater you could probably repair it yourself if you are a motorhead. If the motor has been used in saltwater watch out. Taking apart a lower unit that has been fused together with corrosion and over 20yrs old is near impossible.

Thats one of the reasons I'm buying it, my best friends dad bought a boat with a 3 cylinder johnson and he swears by them. Even if the engine was bad, which it isnt, I heard it run.... 2 stroke outboards are easy to work on.
