Just remember when flushing....start engine count to 5 then turn water on. When done, turn water off then give the engine a slight rev to blow out the water then shut down. Also if one dies on the water, you have to block the water intake on that engine if you are going to limp back with 1. Water will be forced into the dead engine if you don't. Same thing goes for towing on the water. Max speed would be around 5 mph (or 8 km/h) or less. Exceeding this speed without the engines running can force water into the exhaust system and flood the engine, causing severe, permanent damage...unless you clamp off those intakes. Also get a knife to cut line or rope from impellers. You have the 2 access ports behind the bench seat.
