Hi,

Gran Prix, 3.1 eng., 200,000 miles. When starting from a stop, the engine will not accelerate above 10-15 mph. It will do this until you depress the accelerator about half way to the floor, then it takes off like a rocket and runs fine until you slow down or come to a stop and attempt to accelerate again. At times, as I'm traveling at highway speeds, it will start to miss/jerk. This problem is very intermittent. I can put over 200 miles on with no problem then the next day it will happen right away. Drove to the cities last summer (150 miles)and it seemed the further I went the worse the spitting/jerking got. Like I said this is a very intermittent issue. Anyone have issues like this or have any idea whats going on? Thanks.

First thing that came to mind for me was the MAF sensor as well. About 7 years ago we ran into a tun of them that would drive fine but would fall on there face when you hit the on ramps. W

When it does it, unplug the MAF sensor and see if it improves. If it does your on the right track.

      If you really want to treat your wife (and yourself) with a remote operated trolling motor, the Minn Kota Ulterra is about easy as it gets.  Auto stow and deploy is pretty awesome.  You just have to turn the motor on when you go out and that the last time you have to touch it.   24V 80lb.  60 inch shaft is probably the right length for your boat.  They ain’t cheap - about $3k - but neither one of you would have to leave your seat to use it all day.

      Wanderer, thanks for your reply. I do intend for it to be 24 volt, with a thrust of 70-80. Spot lock is a must (my wife is looking forward to not being the anchor person any more).  With my old boat we did quite a lot of pulling shad raps and hot n tots, using the trolling motor. Unlikely that we will fish in whitecaps, did plenty of that when I was younger. I also need a wireless remote, not going back to a foot pedal. We do a fair amount of bobber fishing. I don't think I will bother with a depth finder on the trolling motor. I am leaning toward moving my Garmin depth finder from my old boat to the new one, just because I am so used to it and it works well for me. I am 70 years old and kinda set in my ways...

      Dang, new content and now answers.   First, congrats on the new boat!   My recommendation is to get the most thrust you can in 24V, assuming a boat that size isn’t running 36V.  80 might be tops?  I’m partial to MinnKota.     How do you plan to use the trolling motor is an important question too.     All weather or just nice weather?   Casting a lot or bait dragging?   Bobber or panfish fishing?   Spot lock?  Networked with depth finders?  What brand of depth finders?

      By Crow Hunter · Posted

      We have bought a new boat, which we will be picking up this spring. It is an Alumacraft Competitor 165 sport with a 90 horse Yamaha motor. I will be buying and installing a trolling motor,  wondering if I can get some recommendations on what pound thrust I will want for this boat?  Also, I will be selling my old boat, is there a good way to determine the value on an older boat ( mid-80's with a 75 horse 2-stroke  Mariner motor)  I will appreciate any help with these questions.
