Gulfstream Repower

[SouthPass]

I currently have a 93 Gulfstream hull with bracket mounted twin 2000 model 150hp Evinrude FICHTS with 1500 hrs .
Looking to repower with twin 150hp Yamaha 4 strokes. Any issues with the added weight on this year boat with bracket? I have seen some concern issues with other older model bracket Gradys

I have an '88 Gulfstream with twin Yamaha 2S on a bracket and have been looking into this as well (re-power with Yamaha 4S's). My GW/Yamaha dealer is saying no real issues, either with the weight or the clearance between the engines (on the bracket). The 2 Gulfstreams I have seen re-powered with Yamaha 4S there have been a slight change to the scuppers sitting a tad deeper in the water level:
- Yamahas 2 stroke 25 inch shaft 150's are 426lbs
- Yamaha 4 stroke 25 inch shaft 150's are 475-480lbs

Did you guys consider E-TECs at all? They are lighter, and as shown here, faster, and quieter at cruising speeds (where it counts the most.)

Either way you may want to check your transoms out beforehand. The 2006 repower of my 93 Sailfish came with a $5K transom rebuild cost.

Thanks for the response. I like my Evinrudes and would consider Another pair, however
May have found a pair of 4 stroke Yamaha's at the right price very low hrs plus warranty.
All it takes is mo money!!!
