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. -

I went ahead and watched some of the MLF coverage. Wheeler didn’t make the cut but the bigger story was the Poche/Avera fallout. Kinda funny listening to both sides of the story and putting together the scenario, reading between the lines. -

Question
Scoot
My motor tops out at about 5800 rpms. It's a 4-stroke 115 Yammy. I've always followed the conventional wisdom of not approaching the top rpm's when I'm running from spot to spot. Typically, I'll run at about 4600 to 4800- it's plenty fast and I assumed used less fuel.
However, I've heard recently that this isn't necessarily true. Is it true that 4-strokes will get better fuel efficiency and be easier on the motor when they're run at higher rpms (like 5300 to 5500)? For the life and health of my motor, what's the ideal rpms to run it at? For fuel efficiency, what's the ideal rpms to run it at? If these aren't the same, what's the ideal compromise to run it at?
