lower unit driveshaft 200 hp 1987 OB230110

Someone may have installed a shaft extension kit but I don't think Mercury offered an extension kit for anything over a 150hp. Could be an aftermarket kit.

water pump impeller no good, dropped lower unti to change it, never seen this in 40 years
drive shaft has a coupler on it about 8 splines only about 15 inches long, some one has welded the coupler to the drive shaft so i need to find part numbers for this
did mercury make a 2 piece drive shaft on these models if so I cant find info
