A couple of weekends ago my buddy took his 85 v20 with a 170 hp mercruiser out while I had my 77 V20 out. We ran them together all day and I noticed these differences. When starting off my V jumped way out in front of his but after a half a mile he began to over take me. We ran them wide open for a few miles and he gradually pulled away. My V ran 42 mph and his ran 44. He was taching 4400 rpm, mine tached 3500. The V's have identical engines , hulls, and both are cuddys. The only differences I know of are I have an Elite SS prop with unknown pitch( no numbers or markings) and his is a Quicksilver SS19 pitch and he is running his timing a lot higher than I do. Do you think its the prop or the timing or both making this difference. Also noticed I burnt more fuel per hour than he did. What do yall think?
