I recently purchased a boat that has a Volvo Penta DP-SM Duo-Prop outdrive on it. When the outdrive is trimmed up or down, it moves extremely slow in both directions. I'd say it takes about a minute or longer to go all the way up, or down. I'm used to drives taking about 10-15 seconds maximum. The seller said the trim pump was changed earlier this year by a marina, and they confirmed they changed it.
The fluid level looks normal, could there be air in the system I need to bleed or something like that? And what fluid is used in these pumps in case I want to try to empty and refill the system?
Is there a procedure to bleed the system, or another troubleshooting method I can use? I'm planning on trimming it fully up and down a few times and watch what the fluid level does as my first test, but I looked quick and though the fluid level was normal.
