2007 290 SeaRay DA - Trim Tabs malfunctioning

Hi all,

I am the 2nd owner of this boat and I do not believe any preventative maintenance has been do to the trim tabs. It appears that the level in the reservoir is low. Can someone tell me how to go about adding fluid to the proper level, for I do not see a cap on top of the unit to remove. Also, can you use the same fluid that is specified for the outdrives? If not, can you give me the recommended fluid to use for the trim tabs?


Thank you in advance,

CSMady

Use any type of Automatic Transmission Fluid (ATF). Don’t worry about the exact brand or type – it will all work, and can even be mixed. To add fluid, remove the Lexan cover on the HPU, locate the “filler stack” in the left front corner of the reservoir. There is a round plug sealing the filler stack. Remove the plug and add fluid to the full line on the reservoir. Note: Add fluid only with the trim tabs fully retracted (up). If your reservoir does not have a full line, add fluid so the fluid level is about 1 inch below the top of the reservoir with the trim tabs fully retracted (up). Your Bennett Trim Tab system should not need refilling for several seasons.

Tom,

Thank you for the detailed instructions on the preventative maintenance on trim tabs. I believe that I just may have some automatic transmission fluid on hand. This will be my first project to knock out this weekend.

Thanks again,

CSMady

Groucho,

Thanks for the back-up!
