An engine is always 100% reliable until it fails.
There's some argument of longevity with twins as well. Neither motor is working as hard as a single would through most of it's life.

And while I'm at it there is no such thing a revolutions per minutes.
after much wrenching thought...I decided to go with twin yanmars for my mainship.
I just can't see my self going to the Dry Tourtugas or the bahamas with a single engine. Especially since I already had a failure ( 2 times the engine would not start ) with my current 30 ft. mainship
I had the following problems while away
1) I had a bad pilot starter relay ( burned out )on the yanmar. I now know how to jump start if it should happen again.
2) bad Control Relay ( mainship cheap mexican relay ) that sends power to the computer not alowing the engin to start. I love the mainship ship but they bought a lot of cheap support stuff.
anyway...I've had it with single engins!!
