I am going to install a 40hp OB on the back of my RIB.<br />This is much bigger than any outboard I have had before (25hp is the biggest I had) so I thought I had better find out the best way to install it. <br />The engine has the standard screw bolts on the inside of the mounting bracket. Can I reply on these alone, or do I need to use some form of other fixing too. If so, what sort should I go for - s/s bolts all the way through the transform? Also, what do I need to put on the inside of the transform where the screws on the outboard bracket touch the transform? My transform is very thick, and although I have marine ply on the outside, I have had troubnle putting it on the inside too (with my old 25hp). Do the brackets on larger outboards allow for a thicker transform?<br />Thanks for your help.
