hieghts?

[johnsonm50]

Im working on set up for my hydro to run at Millville, I know Ive got alot of reading up to do but need to know propshaft heights for 20SSH, CSH both Y102 & 350mod, OMC-Merc long skeg. Thanks, Mike

The maximum heigths are as follows: CSH 3/4", 20ssh 1/2", no restriction on 500ccMH (CMH)or 350ccMH. Bear in mind that the heigth is measured at the aft end of the prop shaft and is to the centerline of the shaft. Don't know what you mean by the log skeg OMC. What class?

Thanks Jack, the long skeg is a Merc AB, The OMCs on a Beyer with the Merc adapter- 350 MH. 1, [really many ] more Q, is the height measured with the propshaft parallel to the tru bottom or at the tilt angle you would run?

[Jack Stotts]

You determine the tilt angle based on your testing. Then you measure the heigth at the tail end of the shaft center point. The shaft may or may not be parellel to the bottom depending where you decide your tilt is where you want it Also,there are few heigth restrictions within the Mod category. Only 200ccMh at 1 3/8", 200ccMR at 1 3/8, and 350ccMR at 1" with 25XS engine. Have fun. Wish I could run Millville. Jack
