1. Get the engine running right. I suspect you need, at minimum, carb rebuilds.

2. Once running right, you may be overpropped (common on bass blasters). The engine needs to turn at least 5500 at wide open to perform correctly.

Of course, all of that is moot if you have a weak cylinder. Do a compression check before you stick $1.00 into that engine.

Maybe try a different compression gauge? Then a GOOD decarb.

Re: Evinrude 150 luggs

The normal compression on a 150 will depend on the year of the engine and what type the engine is and what heads are on the block. OMC made both 90 degree crossflow and 60 degree looper engines in the 150 size. Please let us know what model type and year engine you are dealing with.

Re: Evinrude 150 luggs

As long as all readings are within 10lbs or 10% you can assume compression is good, would still recommend a good decarb but the chances of all cylinders being low in equal amounts is almost nil.
