[Tabman II]

Good morning ksr5,

I'm Thomas and I work for Bennett Marine in the Client Service Department.

Installation of trim tabs on your vessel is a very good choice to further inprove your vessel's operating range and confort! A set of 18 x 9's would be a very good choice for your installation, since we are dealing with a 21' vessel and 150 hp outboard. The part number for this kit would 189E, which any of your local marine dealers, catalog &/or Internet retailers can supply to you using this part number. Please use the part number to place your order and shop around for your best deal too! As for the hydraulic line issue; we offer External Line Conversion kits that we can mail to you at No Charge, which allow you to convert our standard through hull actuators to external line type. It is a very easy conversion, since all you have to do is follow the supplied installation instructions and replace the Upper Hinges of the actuators (triangle bases that attach to your transom) with the new ones that have a brass 90 degree elbow installed on the front face of the Upper Hinge. This allows you to route the hydraulic lines down to the actuators from above the water line to complete the installation. If you are interested in the External Line Conversion kit, please email me (trimtabs@earthlink.net) with your mailing address and I will see they leave here by tomorrow at the latest!

If you have anymore questions, please feel free to contact us.

Sincerely,
MJ Thomas
