I am a big fan of the full transom/engine bracket setup, assuming it was done properly. This looks like a factory option on the 92 hull. I know there can be issues with adding a bracket on a hull and changing the center of gravity of the boat.
RickK, it looks to me like your 92 Explorer is the same hull as the Osprey model. Is that correct? Looks like both boats have a 19 degree deadrise. How does your boat ride in a 2-3 foot chop? I need something with a little deeper V than the 12 degrees on my 19-6.
I found this brochure in the photo gallery section. Shows a 230 Explorer with a full transom and an engine bracket. I also found one on the Aquasport/Genmar site for a 1993 model (site appears to be down right now; can't get the link to open).http://www.classicaquasport.com/gallery/showphoto.php?photo=2777&title=aqua-pig-230-explore&cat=561Looks like the bracket was a factory option for the 92/93 model years.
The boat I am looking at has the original Yamaha 130s, so I am hoping the bracket was a factory installation and not an aftermarket modification. The engines are V-4s, which I believe weigh about 360 lbs each, so hopefully the boat sits high enough in the stern and will still self-bail.
RickK, are you happy with the ride of your hull? I figured the 19 degree deadrise would give it a pretty smooth ride in a chop. Have tried to get offshore several times recently in 2-3 footers, and had to turn back because we were getting pounded in my old 19-6.Jim
