Optimax - Low Compression 2004 115 HP

[Bennington Mark]

Just had 115 Optimax in Shop. Built in 2003, 3 cylinder 1.5. Compression is 115, 110 and 90. Can I still run this engine or should I replace powerhead. Are there other options rather than expensive power head replacement.

Before you do anything drastic, look in the archives here for the DECARB process and do it. Then run the engine for a few hours with 2 oz Sea Foam per gallon of gas and then recheck your compression. Let us know what it is.
