Hi all, first time boat owner, first time here. I recently picked up cheap an old '68 "sport" boston whaler, which I'll be restoring the hull (in good shape) and console (all new wood needed, fortunately I do have the old wood to make a pattern). I also was able to find an old '61 Johnson Sea Horse 40hp to go with it (almost like new!). My concern is that the whalers stern is 15" and the shaft of the Johnson is 20". Would it be safe to use a Jack Plate? If so what brand, size, etc. I'm trying to keep the cost reasonable, I know that trying to get a different lower unit is probably more expense than it's worth. Also, is this too much HP for the boat and would using a jack plate make it too unstable or dangerous? Any ideas or thoughts would be helpful. Thanks!
