Transom Bracket - twin outboards

[lobo1]

Must be a few of you guys running twins off of a bracket??

My boat, new to me this spring, is a 78 23' CC totally rebuilt with an Armstrong bracket and twin 2008 Yamaha F-150s.

Sounds nice - looks nice .....runs like crap(in rough water).

The props get air, they slip, the rpms spike etc - whenever in a heavy chop.
I put hydrofoils on both motors and they are nice but I still have most of the problem in rough water - we have heavy chop mixed with our swells here in Michigan.

Today I had the motors lowered to the last hole (down) and will run it tomorrow to see if it is any help.

Anybody else have any issues like this? Anybody run a jack plate to lower the motors DEEP after getting out of the hole (in the chop) -

anybody have any suggestions at all? I have inquired several prop experts and they feel that all props will slip to a certain extent with this bracket/twin setup until I fix the underlying problem...

Thanks in advance -

Steve
