I have the dreaded 3.7 470 Mercrusier I/O and am wondering if ...
A) A swap from my 3" heat exchanger to a 4" is feasible
B) How hard is it and what would I need hardware wise
C) Any pitfalls to watch out for
Thank to all for your help.
I have a Grady White 197 Tournament I/O that has a Mercrusier 470 and am considering going with a bracket mount outboard. Can some of you with this conversion give me pros and cons? Thanks...
