I have a cast aluminum oil pan that I would like to use, but it doesn't clear the part of the jet that sticks up through the bottom of my hull - the sump is too deep. I'm using what I thought was a jetboat specific oil pan with a 7.75" deep sump. If I shim the motor mounts up a little, it will help, but it will change the angles of the driveshaft. What is the maximum difference in angle allowed between the crankshaft and the input shaft on the jet?
