I am looking at an 85hp 1978 johnson. Compression is 120 on all cylinders. Is this good for this engine. Also what is the weight of the engine?...it doesn't have tilt & trim. Thanks...p.s. I am trying to decide whether to get this 85hp or a 1979 115 johnson w/ tilt & trim. Which is the preferred motor by all of the pros here? Is there a big weight difference? This will be going on a 17ft deep vee galaxy bowrider. I don't want to overdue the weight but the boat is rated up to 125hp. thanks all
