OK down to the brass tax on this one.. wasn't easy as I live a million miles from supplies. That and I work 24 7... the wife nick named it the wreck cause it occupied the garage in various states for 4 yrs. Here is my questions.. do I need that large 18 gallon in floor tank with a Honda 40 or has everyone stuck with a portable. And if not what is the tank standard Moeller tank? 2. What is a decent size axle to put under her... got plans for a trailer but it really kinda pops it into a void when it comes to axles. Are you having trouble launching off a flat trailer with a wooden cradle or should I place the boat on a drop down?
