Need advice from the boat owners

[ocean]

My neighbor wants to trade his 150 hp johnson for my 115hp evinrude.His boat is a 20ft riveted aluminum and mine is a 16ft fiberglass.Would 150hp be to much power for the size of my boat? Is johnson a dependable brand? I know my engine is dependable so i know i can trust it starting right up .The johnson fired right up so it starts.The guy wants a smaller engine that wont tear up his boat.If i decide not to trade would anyone be willing to trade a smaller engine for a 150hp?
