From the catalog it appears to be the same basic engine as the 120-140 LOOPERS. The 90 degree loopers have been around since 85, the biggest change they went through was a displacement increase in 88 to a larger bore. They are known by the commercial guys as the die-hards. They are tough! And will rarely leave you stranded if taken care of. I RUN THE SH!T out of my 140 on my bowrider, and it just keeps running better and better. There are a few members here with the same basic engine on there V's, and they seem happy from what I remember from older posts. I know my bowrider runs just as fast with my 85 140 as an identical boat with a 95 150 SUZUKI SUPER SIX BASS edition does(53MPH). It will be a BIG change versus a 115HP cross-flow, as well as better on fuel.
