First question is….. 4 stroke or 2 stroke? Water in a 4 stroke is in the crankcase and so is the reservoir for the oil. The water and oil get mixed and put a white foam all over the inside of the engine. Much bigger problem.
First question is….. 4 stroke or 2 stroke? Water in a 2 stroke is in the crankcase so you need to get it out.
On 2 strokes, especially older skis, flipping and sinking is something that might happen, and if you ride aggressively probably will happen. It is possible to fill a 2 stroke engine with water and clear it and have no long term bad effects.
IMPORTANT NOTE: CLEARING WATER OUT OF AN ENGINE AFTER
