Is it a cheaper quality (not Well known Chinese built) compression gauge? A quality gauge is worth it If you use one regularly. If just using it for looking at a boat, i can understand NOT spending a lot on one. You can possibly find a mechanic that would have a good one to just compare it to just to see how accurate it is. Ive seen cheap ones actually be off by 20#'s & that might cause you to pass on a good motor. Yours probably isnt that far off , but...if it is ???
