I put a double Armstong bracket on the back of a Robalo...he was running V6s and I put the brackets as high as I could in the slash well...(without rebuilding the transom) and put them in the top bolts and he said when he came out of it, water would come up onto the cowling... Id bet if its an outboard boat...you will need to eliminate the splash well ..he eventually rebuild the transom and raised them up, I understand its not exactly the same but maybe that will give you some idea.

At 475 . . . I am going to assume you have 150 optimax motors . . .

You might contact these guys. I think they had twin 150 Optis on their 23 seacraft before repowering with 150 4 strokes.

I thought the 150 Optis were only about 15 lbs heavier than the E-TEC's, 443 lbs when I was looking at them in 2006. Carb'd 150's should be even lighter!

Thanks Denny . . . I was trying to figure that out with the weights too.



1970's 150 inline 6 = 290lbs
Mid 80's v6 Carb 2.0L 150 = 375lbs
Mid 80's v6 Carb 2.4L 150 = 378lbs
Mid 90's v6 Carb 2.0L 150 = 404lbs
Mid 90's v6 Carb 2.5L 150 = 398lbs
2000 2.5L v6 Carb/EFI 150 = 414/424lbs
Optimax v6 150 = 443/455lbs
Verado 4 cyl 150 = 510lbs
2014 150 4 stroke = 455lbs
