J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Swapping the QM for a GM

Jason - my 2GM (13 HP) uses the Kanzakai K2MA transmission and has a gear ratio of 2.62:1

The Yanmar service manual has a chart of transmissions on page 214 at this link (60mb file) http://www.motoren.ath.cx/download.php?filename=yanmar/YanmarGM_HMWorkshopManual.pdf

Look at this page and you can search for similar stuff on the 2QM15 and try to cross reference. http://www.motoren.ath.cx/menus/yanmar.html

I have a 1" diameter shaft and Martec Eliptical Prop Model RH14DX14P
