After winter storage i was getting ready for the boat ready for summer. while doing all my checks i found that my trim on my motor. the motor will raise the engine up with no problem but will not let it down. The hydrolic pump will turn on and pump in both directions. but as it tries to lower the motor it boggs down like there is a blockage. is there some sort of check valve that could be preventing flow?<br /><br />Thank you matt
