Older but clean 2-stroke, 3-cylinder Mercury with working power trim. I tested compression cold before doing any work on this and all three holes pumped right up to an even 135 psi so this will run strong. It has a brand new water pump impeller in it so it pumps water like gangbusters as shown. It has the power trim you want for any rig and definitely need for a pontoon. Do a Cash'n'Carry on it or I can rig on your boat at a negotiated price - I might be persuaded to throw in the installation work. If you have a boat that'll perform well with this much horsepower give me a call.
