    Re: 16ft Avenger project

    Dan, I have a '74 16' Avenger. I run a Merc 135HPV6 on it, but up until last year I ran a merc 150HP inline six. The Inline was about 100# lighter, which was probably better, it tends to take waves/wakes into the splashwell now, at low speed. I have an 18 gal built in tank under the bow. It is a standard flat tank from Moeller, and fits well. It sits on a plywood platform someone (before me) built. I recommend at least a 12 gal tank for you.

    The back of the boat is a bit low, so you may not want to put a bench seat in the rear. Two folks sitting and someone else walks back there you might start taking on water. I have two back-to back seats.

    BTW - with that 90HP force, expect to see no more than 45-50MPH, but only if you have power trim. It takes a lot of power to go faster than 40MPH, even in an Avenger. My 135V6 will allow me to cruise at speeds in the low 50s. Max speed is probably about 60MPH, although I haven't tried that too ofter. I run a 21" pitch Rapture prop, but might be able to spin a 23" pitch prop.

    Also BTW - At full speed (55+MPH), I need to hold the boat very steady or it will chinewalk. However, at 50 MPH it rides rock steady. With the inline six motor the boat was slow to plane, and then would really accelerate. If you did not reduce throttle when the tach hit 3000RPM, the skiier would be launched out of his skiis. This is also the time when the boat would "get away" from a new driver. They were unable to cut throttle while steering, and the boat would hit 50MPH petty quick and scare the heck out of them. The V6 motor has consistant power all the way up the power band. it is not nearly so scary.

    You might do a search on the web for the original brochure for your boat. I found the one for my boat, by matching up it's apperance. The newer Avengers had the "Bubble Decks".

      Dan, One more thought. I have never had trouble keeping the bow down. I would think a bow lifting prop would be the way to go, if you can get one for that motor. You might lift the engine on the transom also. I have mine on a jackplate and most of the way up. The antiventilation plate rides 3/4" above the water.
