so that 150 gives you plenty of power?....the guide is recommending a 200

i never have more than 3 or 4 people on the boat



I replaced the original Yamaha 150 2 stroke with this mercury. Do some research but the Merc 150 4 stroke is a big bore engine that is very powerful. I bought the Mercmonitor Eco gauge which among other things tells you where to trim etc for each power setting for best economy etc. I very often have 6 adults on board running up the coast to dinner etc and we cruise along at 28-30knots without even straining the motor. I couldn't be happier.

My suggestion is to really consider the weight of the replacements motor. I usually have at least 50 gallons in the tank and I would not want any additional engine weight hanging off the back. My battery is now in the console too btw.
