I guess that the 18x10 prop must be a bigger load than something like an apc, 18.1x10. I ran an 18x12 wood carbon hybrid and to my ear it sounded like more than 7900. But I need to verify with a meter to make sure

Clearing the garage for a pair of fine benches my brother got from one of the schools he works for. 3 1/2" thick maple laminated tops, dead flat but need refinishing.

I am finally getting around to the new project I've been looking at for over a year. But first I am finishing the Mintor 38 installation in Aesthesis.

Ed I'll re-install the OS33 in Temptress. Should have that ready by Tuesday or Wed...I'll call you. Need to get real numbers as we did the SAP, 2 years ago. Engine shaft fits the standard apc prop hole so no reaming necessary on your 19x11
