Re: Changing jets to make more HP
Cylinder and crankcase assembly is usually number 1 in the list of parts accompanying the cylinder and crankcase diagram. It does not include cylinder heads under that part number; those are listed separately.
In the instance of the 115, the 90HP crankcase is listed first with its part number, then the 115HP with the different part number:

OK I just talked to the tech at SHOP.EVINRUDE.COM
and he told me that the crankcase is the exact same, no porting difference...whew!!!
and as for the cylinderand crankcase assy, listed as #1... they both include heads, which is why they part number are different..
kinda makes sense, almost everything on the page is probably included in the ASSY
just like a lower unit ASSY...you can buy it all together, or just specific parts.
well i chased it down..
i feel better now about not having that"not really knowing " feeling
he told me the same holds true for the V6 egale 60 degree motors
only difference on the V4 was carbs, throttle body, and heads
sorry for the wide side track...guys
learning more everyday
so my $200 for 4 carbs and throttle bodies, seems to be back into the "good idea" catergory
now onto picking pistons, wiseco or BRP...
take care
