1967 evinrude 3hp compression

[Salt Water Junkie]

I have a '67 3hp I did a compression test on both cylinders and got 50 psi, is that enough?

Have you heard this motor run ? -----Have you tested / calibrated the test guage ?------Many guages / techniques show different results.-----How long have you owned this motor ?

I would say close to normal. Being even is is good. It warrants getting good spark and trying it with some 2 stroke starting fluid or a squirt of
outboard mix.

The motor runs great, starts first pull, idles good, I was just curious because most of my other outboards are in the 70 - 90 psi range. When I tested the 3hp and only got 50 psi, it made me wonder if that was too low.

If it runs good don't worry about it. You may want to do a decarb on it though.

How do I do a decarb ?

With a 3 HP you will need to make a smaller batch of gas mix of course. It would take days to burn a six gallon mix.LOL. My 3hp (1955) compression is 70 lbs. on both cylinders. Best of luck. Rick.
