These motors are internal exposed to a lot of moisture. So, if the ski has not been fogged regularly or has had a rough life, or for that matter just used at all, it needs a thorough rebuild. The 951's are engines that should never just get a top end IMO. The cranks need to be thoroughly inspected & most of the time they will need to be replaced with a rebuilt unit. I have rebuilt several of them using all BRP parts & with machining I have spent nearly $1000 on each. IF you don't have a lot of experience with these engines, I would consider buying a complete rebuilt engine. No, they won't have BRP parts, but they will have a warranty. Its not a whole lot more money & it can take some of the frustration away. DI's are awesome machines in my opinion & I love haw quick & smooth they are. But, there's a lot going on inside them & if one thing is not right, it can spell disaster.
Before you start pouring money into it, makes sure the fuel & air systems are working correctly. Other than crank shaft bearings, the DI's don't normally have engine failure unless something in those two departments are out of whack. Hate to see a person put a new engine in, only to have more troubles.....
Do a search on the forum about fuel pressures & air pressures. There's many threads about what they should be & how they work.
While you can't test the air pump in the ski, you can test the fuel pump by supplying 80 PSI of compressed air to the rail & see if the pump will jump to the 107 it should be on a gage. Engine doesn't have to turn over to do that test, but it will need to still be altogether.

my motor is out on a bench so i wont be able to do the test. engine is very corroded!! the part where the exhaust goes to the big black pipe when i removed the four bolts and removed it i saw the inside diameter some places broke off could this have fallen in the motor? when i tipped the motor to the side a black tar looking liquid poured out from the cylinders!! starter broke off!! what should be next a complete tear down of motor to find out what gave out? previous owner claimed he ran out of oil or something and the ski just died and never started again so he just left it there sitting!! but the oil tank is filled to the top!! i dont want to throw money where its not needed!! or throw money away for that matter!!
A bit more history of the ski would be helpful, how many hrs on the engine, was the ski 'seized' when you acquired it, You say the starter broke off? ,.... Id start by pulling the mag cover to see what damage the starter did to the flywheel gears....then pull the head and inspect cyl's. these are easy covers to remove,
got the ski with some kinda liquid in the cylinders. dont know how many hrs on it. he claimed it was working fine and supposedly ran low on oil to ski shut down and didnt want to start again so he parked it and left it like that. engine didnt want to turn over from starter neither by hand so they told me to remove the pto. still nothing. decided to remove starter as they told me to see if it was stuck to the flywheel it broke the piece whrer the o ring go inside the flywheel area. still wouldnt budge by hand.
