| Maybe try a 19 Rev 4? That would bring the RPM's up a couple hundred. The Rev 4 is a bigger wheel than the Tempest, so it should be harder to turn. You might see some higher RPM's.I know some guys that liked the Tempest Plus on their 690's.
When we set my boats up, we ran a light load to get the rpm's at max. Then tested at full load to make sure it was within the tolerance. I ran a 21 Rev 4 on my 1890 Tuffy with a Merc 200, and my RPM's were about 5300 full load.
