When I had my new Yanmar GM20 installed in my 1973 E-29 the mechanic installed the rear motor mounts at a 45 degree angle. My surveyor says that the motor mounts won't work this way, according to Yanmar, but if I install them inline then the motor will stick out into the salon. The engine runs well and when I watch the mounts they seem to be doing their job. Any thoughts about this, am I going to have some kind of terrible problems in the future?
