On a tangent...I read that motorsailing can have stresses on the engine/trans/shaft mounting that aren't expected in the same way as just motoring.

When the boat is at rest, run lines across the interior of the cabin at a few spots in the general area of the engine. Then go sailing. When heeled over, are the lines still fairly tight? If not, the hull is flexing. What is happening to the motor mount, transmission & prop shaft during this hull flexing??? The more the flex the more you should be concerned with getting out of alignment during motorsailing, if heeling.

"How about Bull Dozer's"
Bulldozers are actually damned expensive equipment, with way more routine maintenance than you might think. You don't just use them and change the oil every six months.(G)
I'd bet the folks at Caterpillar would tell you they don't just drop in truck engines, either.

15 degrees

per Larry Berlin @ Mack Boring. Mine is a 3GMF. The oil sump on a bulldozer is probably like that of our Kenworth truck which holds several gallons, not a few quarts like a little marine diesel.

Something other than damage to the engine to consider if you are motorsailing while heeling over is getting air in the fuel system. If you have port and stb. fuel tanks and a crossover line between them (with the valve open) the fuel will flow to the downside and if your engine pick up is in the high side tank you can suck air in (voice of experience talking).
