Hi Tom, I had a similar problem in one of my engines, in my case it was the rotary valve seal that was defective. the oil was passing from the valve shaft area into the intake valve area. so when you started it cold the accumulated oil in the intake manifold will cause the engine to smoke more than normal. also check as Jeff said the crankshaft seals as it will cause the same condition of excessive smoke

Check the oil injector cable coming off the PTO (aft) carb and make sure it has not come loose/broken. If it has,this will make your oil pump run wide open causing you engine to smoke. (Sea Doo failsafe.)
If the cable is still connected, get a mirror and look at the oil inlection pump on the front of the engine. You should see two lines. One on the pump body and one on the linkage. Those lines should be aligned together while the throttle is at idle. If not then adjust the linkage until they are aligned.
If all of the above is correct and your engine still smokes, Get a pop off pressure gauge and pressure check the crankcase to see if it bleeds down.
A crankcase not holding pressure is usually one of two things:
1. RV seal leaking. Can be replaced without removing the crankshaft or splitting the case.
2. Center crank seals. - Full teardown and rebuild
