Bravo drive will trim up all the way to trailer position just fine. Will not trim down properly. It starts off fine then after an inch or two quickly slows down to a snails pace. The trim pump "whine" has a weaker sound to it with maybe a slight chatter.
Fluid level is OK and everything has worked flawlessly until now.
I'm guessing either a bad ram or some chit caught in the pump valves.
I know there's a screen on the pickup tube, but it seem like if that were clogged, the drive would go down and not up (up takes from the reservoir and down puts fluid back).
ANything I can check/try before having the boat hauled out for diagnosis and service?
