Terry M-(Moderator) 2,203 #7 Posted December 4, 2016 Are you sure??? Looks like a 10 or 12 hp.... 1 Share this post Link to post Share on other sites
Racinbob 11,718 #8 Posted December 4, 2016 That's definitely not an 8 horse. Look at the difference in the size. 10- 16 hp's are basically the same size externally and much bigger than an 8 hp. The 8's also mounted on a riser plate. 3 Share this post Link to post Share on other sites
953 nut 57,841 #9 Posted December 4, 2016 Count your head bolts; an 8 will have seven and a 10, 12 or 14 will have nine. 2 Share this post Link to post Share on other sites
william kirk 11 #10 Posted December 4, 2016 8 bolts that i can see dang things huge! plate calls it an 8 , the guy i bought it from says 8, but i think its to big to be an 8....lmao Share this post Link to post Share on other sites
william kirk 11 #11 Posted December 4, 2016 racin you are right i believe, if yours is an 8 mine is deff not that. yours has about a 2 in raised ring around the screening, mine has about 1/2 in raised area around the screen cover.its got to be a 10 or 12. 2 Share this post Link to post Share on other sites

That's not mine but I just wanted to show you the obvious difference between a big block and the small block 8. The other guys are letting you know the more subtle differences between the 10, 12, 14 & 16 horse motors. All good stuff. 1 Share this post Link to post Share on other sites
