The merc sea pro and Tohatsu and nissan are exactly the same engine made by Tohatsu and as you said way bigger CCs. I believe they are 440 CCs compared to the mercs 400CCs. I'm telling you my 93 merc is just insane with power and with just me in the back and my 75lb daughter today so near 800 lbs give or take a bit we hit 30mph with the 20hp carb never the less. I can't even imagine how much more torque and top end the 25hp carb will give us. Imo the torque alone is worth the switch. Also I have owned the 25hp efi Suzuki but never ran it on the water because I sold it due to wanting the 20hp instead and it ran beautiful in my test tank,smooth as silk and it was just an amazing looking outboard, the technology was insane on it. Light to for a 3 cylinder outboard,136lbs.</blockquote>
