My buddy,the 'expert boater' went along with me the first time out when I bought with a bigger boat,bigger motor. That 65 hp Mercury ended up hanging from the steering cable.What a chore that was,to get it back up on the transom. Luckily got a tow from the first boat that went by.
My 'expert boater' was also the guy that told me "a boat that heavy doesn't need transom straps"..
