The 2006 Merc 5hp 4 stroke
that came with my hard dinghy
has a rusted out/gummed up carb. My inflatable
that I use alternately can take a 6 hp motor
. Can I replace the existing carb on my 5hp engine
with a 6 hp carb and get a little more power?
The owner's manual is shared for 4-5-6 models and shows they share a block and pretty much the engines are the same. So I assume the holes, etc are same.
I called Mercury
and they said the carb was "different" for each 4-5-6 hp model (of course!) and they don't endorse interchanging though acknowledge the different carb may fit. No surprise they don't comment on this probably as CYA, protect differential pricing, etc. I found online some posts from folks that you could swap the carbs as I intend on Tohatsu OBs.
Thanks for any input.
