Sonic 27' Outboards
 

Looking to find outif anyone has some information on Sonic's out board configuration, It has twin 225 Johnsons, trying to get any info on it.

The 27’ outboard is a rare find and may have the engines mounted directly to the transom or on a GIL tubular brackets. If it is an early 90’s boat it may have a Stainless Marine bracket. Post up some pics. With 225’s it will be a low 60mph boat at best. Cool find.

Wow, never seen an OB Sonic W/the splash well.

I had two 24’ twin OBs but boat w/flat transoms.

Great all around boats but as the first Sonic salesman I talked to told me, “beware, they are drivers boats”.

But that was only true on top due to their round keels snd not having a real pad.

Cool boat.

The motors are direct injected Fichts.
Have them gone through.

Lots of hate out there for them but if solid, w/good gas n oil, they are great motors.

looking forward to more pics.

Second guessing myself now…..

Thinking I saw 28’s w/splashwells.

Almost bought one with V-8 Rudes on it and thinking it may have had one.

Was also educated by the Sonic historians that a lot of the 28’s - 32’s were the same boats just had different marketing??

If you decide not to purchase the boat, please post a link to the for sale ad. Thanks.

I'm 90% sure I'm going to buy it. But I will let everyone know. Please keep any information coming that can help. I can't seem to find much info on this particular set-up. What was the max outboard power these would handle?

The 24’s had a design flaw in how they used the rear seat bases to reinforce the transom.

Yours has a different lay out so probably not an issue.

Worst case would be adding reinforcing knees.

That being done, it’s screaming for a pair of 450R’s.

Those motors are 550 lbs per, meaning you can get to 300 HP w/new motors at similar weight.

Thats a net gain of 150 HP w/no weight penalty.

One negative to those motors though, they’re basically worthless for retail.

If both are solid, w/motor specific rigging, you might get $2500 - $4k for everything.

i was a sonic dealer for jay back in the day, we had a 24 with 200 mercury's , ran good in rough water and a handful in came water , as that was a copy of a 24 donzi , had a rounded bottom . that 27 was a different boat then the 24 .

Here’s one of my 24’s.
