So I got a Tohatsu MFS15C and after studying the parts list, the only difference I can find between the 15 and 20 hp is swapping the following parts in the carb:
"main jet" to 3BJ-04421-0
"plug" to 3V2-03169-0
"slow jet" to 3BJ-04552-0
"main nozzle" to 3BJ-03141-0
However, there was an old thread that I found where Tohatsu Guru would check if the carb housing was identical as well but there was no answer to that question unfortunately.. From the parts list I can not see that there is any other difference than above?
Can someone help me out here, it seems to be a fairly simple way of getting the 20hp for just a few bucks I think. The other, more expensive, way of doing it is to swap the entire carb.
