93 Intruder Compression Question. Help

[21cborden]

Just ran a compression check and all cylinders are at 60. Should I be concerned?

60 PSI is defenately low.

the positive thing is that there all even at 60.

so what i would do is get a other gauge and test it again.

if its still 60 with a new gauge i would decarb the hell out of it
hophely it will come back up
has it been sitting for a long period?

I agree with reeldutch. The gauges are notoriously inaccurate as far as the specific number reading goes but they are good for telling if the cylinders are even or not. You MAY be ok.

Thanks for the quick response! We were actually just talking about wondering if it might be the gauge because the boat just came back from the shop. Dont have another gauge to check it with guess I will have to borrow one. What is the best way to decarb. it? This motor is on a boat we were actually looking to buy and that is what got us so concerned about it being in the 60 range. Boat ran about 55 and didnt miss a lick. Thanks again

It is not unusual for one of those big low compression V6s in good health to compress 60psi.

Quit worrying about it and go fix something that is broke.
