Impressive project- I have a question maybe you or someone else can answer- about the swim platform, transom bracket, I see many of the i/o to twin outboard conversion use a swim platform, giving a long setback…why are these swim platforms used instead of two traditional hydraulic jack plates?

Simply put, the sealed swim platform adds some flotation to assist supporting the added weight hanging off the stern. Also less turbulence at the lower units aide in getting on plane.

Wouldn't individual jackplates do the same thing except for adding buoyancy? Although seems like the i/o conversions Ive seen have an extreme setback of roughly 2 feet and your typical jackplate is a foot, does the i/o conversions need that extreem of a setback to get the lower units in good water? Would it also have anything to do with making sure the engines are at the same exact height as I havent seen swim platforms with hydrualic jackplates on them

I can’t definitively answer your question, my experience is from long ago when I put that platform on my triple engine Sonic and it replaced the old style “pipe” Gil brackets.

The added flotation of a full bracket/platform is a big part (huge impact at rest/anchor) but I really like the side to side rigidity added also.
Ive restored two Sonic OBs w/twin Gil tube brackets and both transoms were seriously bowed out/aft due to those.
Honestly, most cones from poor/no engineering of changing an IO hull to OB.
The difference in internal loading (lack of design change) is huge!
This is particularly true on the 24’ Sonic OBs.I'd rather be competitive w/junk I built in my garage than win w/stuff I bought.
I refuse to allow common sense to interfere w/my boat buying decisions.

besides the added flotation, one of the main reasons for so much more setback is to be able to trim the motors fully up without the cowling hitting the transom, most outboards need 23 inches of setback to clear the transom. as far as the swim platform goes, you have to look at location, we live in florida, we can swim/dive almost year round, the swim platform is a necessity for us.
the boat is currently back on the market, my friend Kris who owns the boat now has already purchased another boat and must sell

if anyone is interested here is a link to the boat that replaced this one. i partnered with one of my clients on a new Fountain 38TE with triple 400's, its quite the thread with many upgrades posted. a year after we picked the boat up i fully de-rigged the triple 400's and re-rigged with quad 400's. https://www.thehulltruth.com/boating...ure-heavy.htmlLast edited by aswaff400; 11-27-2022 at 06:25 PM.
