[QUOTE="Captain Ahab, post: 4759, member: 10"] Most common cause of blown motors is improper cooling! Flush teh motor with clean water after each use, do not run the engine without a strong water flow, ever! Change the impeller each year, change or clean the screens as well. Do not redline the engine! A big motor on a small boat can, and will cavitate and that can allow air into the water intakes, as well as cause the motor to spin without proper pressure from the lower unit. This is especially true doing a turn. I have only had one power head go on me in almost 30 years of running outboard boats and that was a manufactures defect covered under warranty. I do constant maintenance on the motors, follow the factory guides and change the lower unit oil at least once a year (I run 2 strokes so no other oil to change). Take care of the motor and do not push it and they will last. [/QUOTE]
