Convert 90HP to 115HP

[jrgiust]

My brother has a 2006 90 4stro

My brother has a 2006 90 4stroke and he was wondering how to convert it to a 115. Does anyone know if it is just a chip or a hole lot more? Can it be done and is it even worth it? Thanks.

"They are not the same block.

"They are not the same block.

The 75/90 horse share a 97.4 cu in block the 115 uses a 106.2 cu in.

So "no can do" - and besides, in "on boat" performance moving up from a 90 to a 115 will only gain you about 3 mph at the top end under perfect conditions.

If he want's MORE power you would need to move up from an inline 4 motor to a V6 to see any difference you would notice...."
