thanks for the explanation

Yep, you swapped from a 175 to a 175, so performance will be about the same. But like you found out, the 2.4L MERCURY is ALOT better on fuel than the old OMC crossflow was. Reprop to a stainless prop, and let it turn up to at least 5300 and it should do a bit better performance wise. And take care of that 2.4L MERC as it is a good engine.
