Hi Tim,

I collected as many numbers as I could on this and the range from users was 6800-7200 on a Zinger Pro 22X8. It was not obvious from all postings, but I would assume they were all fairly new motors. Keith from BME's numbers on a broken in motor were Mejzlik 22x10 at 7180 and a Mejzlik 20x10 at 8300.

Numbers from my Taurus 2.6 was 7150 on a Zinger pro 22X8.
At least two other people with the same engine were getting within 50 RPM on their new Taurus 2.6's on the same prop. On a broken in 2.6 with a Mejzlik 20X10 a guy was getting 8200RPM. Remember Zinger Pro's, Menz S's, and Mejzlik's in the same size produce very different RPM results, with Mejzlik the highest, Zinger in the middle and Menz the lowest with the highest load/widest blade.

I have only one source of numbers on the Taurus 3.2, but his numbers are from two examples.

Mejzlik 22/10 - 7200
Menz S 22/10 - 7000
Mejzlik 22/8 - 7900

I hope this helps.
