I just recently got my first I/O, a 2.3 powered sportsman 1900 by Blue Fin/Spectrum. Is a 19ft aluminum. Replaced points with pertronix and getting it ready for the water, system by system. I replaced the impeller, previous one was torched, and attached the muffs at full blast. First start gave a good puff of dirty smoke/steam? and then is running clear. Water looks to be circulating appropriately and exiting exhaust around the Outdrive. Oil shows just a hint of water evidence. All cylinders check out at 150psi on compression test. Could a leaky riser gasket or small leak in the head gasket cause a very small amount of water in the oil? Next step is pressure testing the block for leaks, gotta build the contraption though.
