I have an '07 248LS with Volvo-Penta 5.7GXi DP with the factory installed Bennett trim tabs. I don't recall the size but you might want to call Monterey in Williston Florida and inquire directly what they installed from the factory. Another option would be to call Bennett in Deerfield Beach, Florida or try their web site. I had a clilp that was broken and since I live near Deerfield Beach I just dropped in at the Bennett headquarters to see if I could purchase a new wire and clip. They were very polite and helpful and since I did not know what model Bennett system I had, they took out serveral manuals to identify the part I needed. Finally they gave me the part "no charge" and told me to come back if I ran into any other problems.
