Oh my gracious, jb....I can just visualize your nasal venting! It has been hard for me to hold back on the comments, so I will continue my restraint. On a serious note....Sam-couldn't agree more. We had some squirrely times when we first put the 48 spl on the last restore(the son's). He was in quite a quandary as the engine just needed to go down a smidgen as the boat was loose & porpoising. Felt like we were hydroplaning & going to jackknife at any moment. As he had already finished his transom, he chose against notching it out & instead going the jackplate route. (My advice was to notch, but I should have told him to jackplate seein' as he always does the exact opposite!). It amazes me what difference an inch or two can do for not only the boat handling, mph, etc. etc....Whew....there.....I did it.....kept this post professional & informative...(note to self...you will encounter performance problems whether the shaft is too deep relative to the planning surface of the hull or if it is too shallow...positioning is critical!....got it!!)
